Coroner offers new details about fatal slaying of 4 U of Idaho students after preliminary autopsies

The local coroner is offering more details about the brutal slaying of four college students in Moscow, Idaho, early Nov. 13.

The autopsies for Madison Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20, and Ethan Chapin, 20, were completed Nov. 16, Latah County Coroner Cathy Mabbutt said.

In an interview with NBC News Nov. 17, Mabbutt said the autopsy gave a clearer picture of what time the four were killed, their “extensive” wounds, and what the murder weapon was.

"It would have been early in the morning, sometime after 2 a.m., but still during the night," Mabbutt said, adding that there wasn't a medical way to determine who was attacked first, but investigators are "trying to put timelines together with other text messages and other technology."

She said that the murder weapon "would have been a bigger knife" to be consistent with their "pretty extensive" wounds.

Mabbutt said that the victims showed "little bit of bruising" but "nothing significant." She added that some bruising "wouldn't be uncommon during a stabbing."

Mabbutt couldn't say how many times each victim was stabbed but said it was safe to say each of them had multiple wounds. She declined to say where on the body they were stabbed and later clarified that the victims were stabbed in different places and a different amount of times.

Mabbutt said it was likely the four had bled out in the home.

She said DNA samples have been taken from the scene and are being processed. When pressed, she said it was "possible" that some of the DNA being tested may not be of the four victims.

"There were nail clippings that were taken, and other ones that are being sent off, and so that will be processed," she said.

They are awaiting final autopsy results, which will not be available for another four to six weeks, pending toxicology. Mabbutt said in this case, the toxicology reports likely wouldn't be important to the investigation.

She added that the autopsies were completed by Spokane Medical Examiners Office — located in Spokane, Washington, about 90 minutes northwest of Moscow — but she responded to the scene a few hours after police were called.

"It’s pretty traumatic when there’s four dead college students ... who’ve been stabbed to death in one location," she said, adding that there was “quite a bit” of blood at the scene.

"I’ve been coroner for 16 years... we have had multiple (victim) murders in the past, but nothing, nothing like this," she said.

Police said that they did not have any suspects and were still looking for whoever was responsible for the deaths of the four friends.

“We cannot say that there is no threat to the community,” Moscow Police Chief James Fry said at a press conference on Nov. 16. “There is a threat out there, possibly.”

“We do not have a suspect at this time, and that individual is still out there,” he added. “We cannot say there is no threat to the community.”

Fry said that two additional roommates had been home at the time of the killings but they were not considered witnesses and are actively cooperating with the investigation. He said the 911 call came in at noon on Sunday morning — hours after authorities believe the four were killed.

The morning of Nov. 17, Latah County Prosecuting Attorney Bill Thompson told TODAY that it "certainly is possible" there could be more than one suspect in the case.

“The fact of the matter is whoever’s responsible for these murders is still at large,” he said. “The investigators do not know who that person is.”

Never-before-seen photos and details about the man accused of murdering four Idaho college students

By Peter Van Sant

January 7, 2023 / 11:02 PM EST / CBS News

Under a dark Idaho sky, investigators flew Bryan Kohberger to the college town of Moscow. Police delivered him to the Latah County Jail. On Jan. 5, in an orange jumpsuit, his face vacant, the 28-year-old made what will likely be his first of many appearances in this court.  

He stands charged with the murder of four students from the University of Idaho: Kaylee Goncalves, Madison "Maddie" Mogen, Ethan Chapin and Xana Kernodle. Investigators say he stabbed them to death in the home the women shared. 

JUDGE: The maximum penalty for this offense, if you plead guilty or be found guilty is up to  death and imprisonment for life. Do you understand?  

BRYAN KOHBERGER: Yes.  

Kohberger has not yet entered a plea.

In an affidavit , investigators laid out their understanding of the grim details about the night of the killings:  They say the killer left his DNA on a "leather knife sheath" found on a bed next to Maddie Mogen. And, most hauntingly, they say a surviving roommate thought she heard crying and "saw a figure clad in black clothing and a mask."    

The man walked past, as she stood in "frozen shock."  She locked herself in her room.  

The investigation is fast-moving. Authorities have not disclosed a motive or if he had a connection to the students, but we are learning more about just who Bryan Kohberger is.   

WHO IS ACCUSED KILLER BRYAN KOHBERGER?

Just 15 days before his arrest, Bryan Kohberger and his father were driving home from Washington State University for winter break to the family's home in Pennsylvania.

OFFICER (body cam video): Hello MICHAEL KOHBERGER: How you doing? OFFICER: How ya'll doin today?

The journey interrupted by two traffic stops, almost 10 minutes apart, in Indiana for tailgating.

MICHAEL KOHBERGER (to officer): We're gonna be going to Pennsylvania, a couple more miles. OFFICER: Oh, OK. MICHAEL KOHBERGER: …to the Pocono Mountains. We're a little, we're slightly punchy. We've been driving for hours. 

Police body cam video shows Kohberger and his father talking calmly with an officer about the trip.

OFFICER: Hours? And days? BRYAN KOHBERGER: Hours. MICHAEL KOHBERGER: Hours. Well, we've been driving for almost a day. OFFICER: Do me a favor and don't follow too close, OK?  

Then they are released with a warning.

Kohberger had been at the university since August, studying to get his Ph.D. in criminology. He was also a teaching assistant in the Department of Criminal Justice. He lived in an apartment complex on campus and had an office there.

According to the newly released affidavit, Kohberger had applied for an internship with the Pullman Police Department in the fall. He wrote in his application essay that "he had interest in assisting rural law enforcement agencies with how to better collect and analyze technological data."

Benjamin Roberts took four classes with Kohberger.

Benjamin Roberts : He seemed very comfortable around other people. He was very quick to offer his opinion and thoughts. And he was always participating fairly eagerly in classroom discussions.

He says Kohberger appeared highly intelligent.

Peter Van Sant : Does anything else come to mind that Bryan said to you in the past that today you think might be of interest?

Benjamin Roberts : There was a comment that he made, and it was kind of a flippant guy talk thing. At one point, he just idly mentioned, you know, "I can go down to a bar or a club and pretty much have any lady I want."

Kohberger arrived at the university after earning his bachelor's in psychology and master's degree in criminal justice at DeSales University in Center Valley, Pennsylvania.  

While at DeSales, authorities say Bryan Kohberger posted this survey, approved by the university, on the website Reddit asking ex-cons about the crimes they committed. One question he asked: "Before making your move, how did you approach the victim or target?

James Gagliano : This could be a piece of circumstantial evidence.

James Gagliano is a retired FBI Supervisory Special Agent and CBS News consultant.

James Gagliano: The fact that the suspect was interested in pursuing a Ph.D. in criminal justice and was especially interested in … the mental state that people who had committed murders in the past … yes, it could be interesting to note. But I know a lot of researchers that study those things, too, that would never commit a quadruple homicide.

And if Kohberger was involved in these murders, genetic genealogist CeCe Moore questions why he would be so careless as to allegedly leave his DNA at the crime scene. 

CeCe Moore : People are talking about how smart he supposedly is. And I just can't see how that could be true, because any student of forensic science or criminology would have to know that it's virtually impossible not to leave your DNA behind at a very violent, intimate crime scene like this.

CeCe Moore : You know, Ted Bundy thought he was smart. But he wasn't that smart, as it turns out.

After the murders, Roberts says Kohberger appeared disheveled, tired and chattier than usual.

But nothing could prepare Roberts for what he learned o f Kohberger's arrest.

Benjamin Roberts : Looking back over the last four months, I feel like there should have been signs that I should have seen. And I didn't ... I was blindsided.

Jason LaBar : This is out of character for Bryan, these allegations.

Monroe County public defender Jason LaBar represented Kohberger before he was extradited to Idaho.

Jason LaBar : The family would want the general public to know that Bryan is a caring son and brother —that's he's responsible, that he is devoted to them.

In a statement the family said, "we care deeply for the for the four families who have lost their precious children" ... and that they "seek the truth and promote his presumption of innocence rather than judge unknown facts and make erroneous assumptions."

Jason LaBar : He is innocent until proven otherwise.

LaBar says Kohberger came from a close-knit family. He grew up in eastern Pennsylvania in the Pocono Mountains. His father was as a maintenance worker and his mom worked in the school system. Bryan has two older sisters – one who works as a family therapist, and another sister who appeared in a 2011 low budget slasher film, "Two Days Back," about a group of young students viciously murdered by a serial killer. She now works as a school counselor. 

Bree : My heart goes out to Bryan's family.

Kohberger's friend, Bree, says she met Bryan at a party when they attended Pleasant Valley High School. She asked "48 Hours" not to use her last name.

Bree : Bryan was really funny. He wasn't outgoing at all. But he also wasn't shy.

She says they bonded over their love of the outdoors.

Bree : I don't necessarily remember the conversations, but you definitely remember how someone makes you feel. … I just remember feeling OK — I was just with a friend. … Just felt natural.

Bree recalls Kohberger was an average student with only a few close friends. In a yearbook photo, Kohberger's caption said he aspired to be an Army Ranger.

Casey Artnz also knew Kohberger from high school . She posted this Tik Tok following Bryan's arrest.

CASEY ARNTZ TIK TOK: "I used to be friends with Bryan Kohberger" ... "I'm in actual shock right now."

Casey Arntz : He was an overweight kid. … So, he did get bullied a lot.

But Arntz says people saw a change in Kohberger the beginning of senior year.

Casey Arntz : He lost like 100 pounds . … He was a rail. … It was after that weight loss that a lot of people noticed a huge switch in him.

Casey Arntz : My brother has since come out to say that even though they were friends, Bryan bullied him.

Casey Arntz : He had said that he would put him in like a chokeholds and stuff like that.

Bree says Kohberger started using heroin, which ended their friendship.

Bree : You just saw him becoming more self-destructive. … He really stayed secluded.

It's unclear when exactly Kohberger went into recovery, but both Bree and Casey say years after he graduated high school it appeared as if he was getting his life together. He was going to Northampton Community College and working security for Pleasant Valley School District.

Bree : He was telling me that he wanted to get sober, that he was getting sober. … And he wanted to let me know like, "I'm gonna do better. I'm gonna be better."

Bree : I'm sorry ... (emotional)

 Casey Arntz : The last time I saw Bryan was in 2017 at one of my friend's wedding. … And I gave him a hug and I said, "You look so good. Like I'm so proud of you."

And both Bree and Casey say it appeared that Kohberger had a new focus — his studies in criminology.

Bree : He wanted to do something that impacted people in a good way.

Bree: People were not his strong suit. And think through his criminology studies, he was really trying to understand humans and to try and understand himself.

Now Bree, like many who knew him, struggles to connect the person they once knew to this unspeakable crime.

Bree : I think a lot of people who were close to him are feeling this massive amount of guilt … "Why didn't I see it? Did I miss something? … Where did it go wrong?

THE YOUNG LIVES LOST

Before it was a crime scene, it was a home to five close friends. Maybe none closer than Maddie Mogen and Kaylee Goncalves.

On TikTok, the 21-year-old seniors looked like they were enjoying their final school year.

In the early morning of November 13, the two friends headed to a food truck. But their seemingly carefree existence would come to an abrupt end just hours later. Kaylee and Maddie were stabbed to death in the upstairs part of the house. A hundred miles away in northern Idaho, Kaylee's father Steve got the news.

Peter Van Sant : Steve, give us a sense of the shock of that moment.

Steve Goncalves : You just feel like you're getting crushed by a thousand pounds of weight.

Peter Van Sant : What do you want the world to know about your daughter, Kaylee?

Steve Goncalves : I want the world to know, they — they got robbed. Somebody stole from you.

Steve Goncalves says his daughter Kaylee would have made the world a better place. A general studies major, she was the middle child of five siblings. Goncalves says Kaylee was always up for a challenge.

Steve Goncalves : She grew up around two boys that were, you know, older than her. And uh, she didn't see any reason why she couldn't be as quick and fast and as good as those two boys were.

Peter Van Sant : What did she want to do with her life?

Steve Goncalves : Like most young people, it changed. She was gonna be a teacher. … But once she found out how long it was gonna take to pay back her student loans, she — she said, "Dad, you know, this thing that you do with computers seems to work pretty well."

She reportedly had a job lined up in Austin but made it clear that one day she hoped to settle down somewhere near her dearest friend Maddie Mogen.  Maddie was a marketing major, and she and Kaylee had been inseparable since the sixth grade.

Steve Goncalves : I just felt like it was more of a sistership than it was a friendship ... And she was just one of our kids.

So, it perhaps did not come as a surprise when Steve revealed at a November memorial that Kaylee and Maddie died side-by-side.

STEVE GONCALVES (memorial service): They went to high school together. … They came here together. … And in the end, they died together. In the same room, in the same bed. It comforts us. It lets us know that they were with their best friends in the whole world.

It was a belief Maddie's stepfather, Scott Laramie, repeated to another packed memorial just days later.

SCOTT LARAMIE (memorial service): The two of 'em were a force to be reckoned with. They stuck together through everything.

Maddie had a boyfriend, Jake Schriger.

JAKE SCHRIGER (memorial service): She was the first person I talked to every morning and the last person I talked to before bed.

They had been together for more than a year. Schriger says Maddie had a talent for making people laugh.

JAKE SCHRIGER (memorial service): She was really funny. Her jokes really would come outta nowhere … And just be like, "Is that the — the cute little blonde girl that just said that?"

But Maddie and Kaylee weren't the only victims.  While two other roommates were in their rooms and unharmed during the attacks, on the second floor, the killer made his way to the room of Xana Kernodle.

JAZZMIN KERNODLE (memorial service): She was my baby sister, but she was so much wiser.

Xana's sister, Jazzmin.

JAZZMIN KERNODLE (memorial service): She would always tell me she wouldn't know what to do without me. And now I have to live this life without her.

A 20-year-old junior majoring in marketing, Xana was known for being focused on her studies. So focused, she didn't make much time for dating.

JAZZMIN KERNODLE (memorial service): Xana never had a boyfriend before, and my dad and I wondered if she was ever gonna get one (laughs).

That was until she met Ethan Chapin.

JAZZMIN KERNODLE (memorial service): The way she would talk and smile about him was something I've never seen her do before.

Ethan was a 20-year-old majoring in recreation and tourism management. Jazzmin says Xana and Ethan began dating in the spring of 2022.

JAZZMIN KERNODLE (memorial service): They had something so special and everyone around them knew.

Especially anyone who followed the pair on Instagram. For Ethan's birthday, Xana posted photos of them with the caption: "Life is so much better with you in it, love you!" It would be her last Instagram post. Just two weeks later, the young couple was found stabbed to death in Xana's bedroom.

At the University of Idaho, the pain of this tragedy is felt at the root and extends hundreds of miles away to a tulip farm in Skagit Valley, Washington. It's where Ethan worked before heading to college. His boss, Andrew Miller.

Andrew Miller : So, Ethan started – it was in the spring of — of '21. … It was the best Tulip Festival.

Miller says the annual tulip festival attracts close to half-a-million visitors, and Ethan stood out in the crowd.

Andrew Miller : Well, he's a big guy wearin' a big smile, right? I think that's the part that I – that kinda struck me right away.

Ethan – a triplet – worked there with his siblings, Maizie and Hunter, and lived in a rented house on the farm with their parents. The Chapin triplets were incredibly close says Reese Gardner.

Reese Gardner :  They were best friends. … If one did something, they all did something. … It was pretty cool to see.

Including attending the University of Idaho together.

Andrew Miller : And that was the funniest thing, it was like, of course it was a package deal. Like, all three of 'em were gonna go there.

Ariah Macagba : He was excited, I think, 'cause his siblings were going with him.

Ariah Macagba says Ethan's parents had decided to live in Idaho, too. Macagba says when she heard Ethan had been murdered, she couldn't believe it.  

Ariah Macagba : I think the first thing I did was message Ethan. I was like, "Hey, you're OK, right? Like, this isn't real." (crying) And — obviously, he didn't respond.

Reese Gardner scoured the internet for information.

Reese Gardner : And I just couldn't stop reading articles and … I just wanted to know what happened, and I wanted to know why.

But in lieu of answers, Gardner turned to tulips. He had an idea: name one after Ethan.

Reese Gardner : I thought, "There's — there's no better way … to remember someone who had such a big part, a big role in those farms."

Andrew Miller : Cause Reese called me … And it was, "Hey, can this be done, and are you interested in doing it?" And I was, "Yes, and hell yes."

But creating a new tulip is a long process, so instead, Miller suggested a mix of tulips that would be a perfect tribute to Ethan: yellow and white.

Andrew Miller : Yellow, of course, because Go Vandals. University of Idaho, right? That's significant. And then white is — is an eternal color, right? And tulips come up in the spring. It is a symbol of — of hope.

With his parents' blessing, they named the mix of tulips, "Ethan's Smile."

Andrew Miller : So, this will be a nice yellow or white tulip here in about four months.

The trio planted thousands of bulbs in the state of Washington and sent a couple thousand more to the University of Idaho.

Andrew Miller : And it really is our hope that we'll be able to continue to plant and that anybody that wants to remember him will be able to have their own Ethan's — Ethan's Smile Garden. …  It's a living legacy.

Now it is up to prosecutors to get justice for these young victims .

IN SEARCH OF ANSWERS

Forty-seven days after the murders of Kaylee Goncalves, Ethan Chapin, Madison Mogen, and Xana Kernodle, authorities apprehended the man they believed was responsible.  We now know investigators had Bryan Kohberger in their sights early on but kept it close to the vest. So, in the early days, after the Nov. 13 murders, frustration swept over Moscow, Idaho.

James Gagliano : I think in this instance people were expecting a pretty quick arrest in this case, and it takes time.

Steve Goncalves, father of 21-year-old Kaylee, was trying as best he could to deal with news no one expects.

Steve Goncalves : Most things I'm prepared for. Most things as a dad, you can— you can handle. But somethin' like that, you just can't prepare for and you can't fix it.

Steve Goncalves : And, you know, just think if you do everything right, by the book, somethin' like this couldn't happen.

Peter Van Sant : Did you have any sense who might have done something like this?

Steve Goncalves : No … I didn't think anybody in her inner circles was — was capable of interacting and — and her doing something that could even deserve something like that.

As news spread of the murders, so did shock in the college community, which had not seen a homicide since 2015.

Matt Loveless : Parents drove hundreds of miles to pick up their kids to head home and stay home for the semester.

Matt Loveless is a journalism professor at nearby Washington State University.

Matt Loveless : At this point, we don't know if they're gonna come back for — the spring semester there on campus. And that same thing happened in both our communities.

James Gagliano: And, so, when parents send their kids off to school, for something to happen like this, I think it's a parent's worst nightmare

James Gagliano : And it's a place, Moscow, Idaho, where violent crime really is not an issue.

As police started their investigation, they traced the victims' final steps. The day before the murders seemed to start ordinarily. Kaylee Goncalves posted photos with her roommates and Ethan Chapin, to her Instagram account with the caption, "One lucky girl to be surrounded by these ppl everyday." That evening, Ethan and Xana attended a party at a fraternity house on campus.  Kaylee and Madison were at a bar between 10 p.m. and 1:30 a.m. They were then seen at a local food vendor, the "Grub Truck."  It is believed they all returned home by about 2 a.m. on Nov. 13.

James Gagliano : So, in examining the timeline , police know that the crime took place sometime in the early morning hours. There were also two other University of Idaho students who were inside the house when the murders took place.

It was later that morning that a call was made to 911 from one of the surviving roommate's phones to report an unconscious person.  Police arrived at the house at 11:58 a.m.

James Gagliano : Police find the victims on the second and third floor of the house in bedrooms — a horrific and a very large-scale crime scene 'cause you're gonna be dealing with a number of different floors that need to be processed, the bedrooms where the crimes actually occurred, and then ingress and egress points. How did the — how did the alleged killer get inside the house? Through a front door? Through a window? Those are all things police will be looking at.

CHIEF JAMES FRY (to reporters): No weapon has been located at this time. There was no sign of forced entry into the residence.

On Nov. 16, three days after the murders, the Moscow Police held their first press conference.

CHIEF JAMES FRY (to reporters): We believe this was an isolated, targeted attack on our victims. We do not have a suspect at this time and that individual is still out there.

Coroner Cathy Mabbutt issued her report on Nov. 17.

Coroner Cathy Mabbutt: They were all murdered through stabbing with some kind of a, probably a larger knife…

She told police some of the four victims had defensive wounds, but none had signs of sexual assault.  Police continued to work the case, aided by the Idaho State Police and the FBI.

James Gagliano : I just believe that the Moscow Police Department probably just didn't have a lot of experience in working a homicide, especially one as heinous as this one.  

After about three weeks with no arrests, and what, to the public, appeared to be no real suspects, Steve Goncalves grew more concerned that authorities weren't doing enough and that the murders would turn into a cold case. So, he says, he started working with his own team to investigate the murders.

Steve Goncalves : So, we just thought, "This is the time. Let's get it out there, and let's not let it get cold. Let's get as many resources as— as possible."

Peter Van Sant : And did you have any sense whatsoever as to what a motive … might have been for these murders?

Steve Goncalves : Pretty girls and a handsome guy. I thought, you know, that might be somethin' to do with their, you know, stalking them in the sense of that.

Meanwhile, names of possible people of interest were trickling out — including members of the community and acquaintances of the victims. But they all seemed to be part of an unfounded rumor mill, many from online sleuths.  Goncalves even had people come to him to prove they were not involved.

Steve Goncalves : We — had certain suspects take their shirts off in our kitchen to show if they had scratches. And we tried to do everything in — in our powers to make sure that if we thought somebody was ruled out, we truly — we truly felt like, you know, we — we looked at 'em.

Law enforcement would end up receiving thousands of tips, but the investigation, by outward appearances, seemed to be stalled.  Nearly a month after the murders, on Dec. 7, police were seen packing up the victims' belongings to return to the families, who had lost so much. It was the police chief behind the wheel of the U-Haul truck. That same day, a plea was made to the public.

Police were interested in speaking with the occupant(s) of a white 2011-2013 Hyundai Elantra with an unknown license plate, spotted near the crime scene, around the time of the killings.

AMANDA ROLEY | KREM REPORTER: Today's update is the first descriptive tip that we have received in several days. Detectives now want to speak with anyone who was inside a white Hyundai Elantra that was near this home on King Road around Nov. 13th.  

Police released photos of similar makes to the vehicle they were looking for.

CHIEF JAMES FRY (to reporters): We still believe there is more information to be gathered.

James Gagliano : Pushing that out to the media. Pushing that out to people on the internet. Pushing that out so that people can look for either a potential suspect, person of interest, or a potential vehicle. That goes a long way towards running down leads.

INSIDE THE INVESTIGATION

It turns out that about two weeks before the police asked the public to be on the lookout for a white Hyundai Elantra , they had already shared that information with surrounding law enforcement. And on Nov. 29, 2022, a white Elantra was located by Washington State University Police. The car was registered to Bryan Kohberger.

CBS News learned, that in mid-December, the Hyundai Elantra was tracked for several days by the FBI, using E-ZPass monitoring, fixed wing aircraft and ground support, as it was driven by Kohberger, along with his father, from Pullman, Washington, on that cross-country trip to the family's home in Pennsylvania.

On Dec. 15, the car was stopped twice in Indiana for those driving violations, by the Indiana State Police and the Hancock Sheriff's Office.

OFFICER: So, you're coming from Washington State University? MICHAEL KOHBERGER: Yeah. BRYAN KOHBERGER: Yup OFFICER: And you're going where? MICHAEL KOHBERGER: We're gonna be going to Pennsylvania.

Both agencies said at the time of the stops, "there was no information available on a suspect for the crime in Idaho, to include identifying information or any specific information related to the license plate state or number of the white Hyundai Elantra …" 

Police did not ticket Kohberger; they gave a verbal warning and the trip continued home. And then, Kohberger's holiday came to an abrupt halt . 

CBS NEWS REPORT:  A suspect is under arrest for the quadruple murder of four Idaho college students.

On Dec. 30, 2022, police made that announcement that Bryan Kohberger was under arrest for the murders. He was arrested at his family's home in Albrightsville, Pa., at 3 a.m., with approximately 50 law enforcement officers on the scene. 

MAJ. CHRISTOPHER PARIS | PENNSYLVANIA STATE POLICE: There were multiple windows that were broken I believe to gain access, as well as multiple doors.

Authorities believe Bryan Kohberger acted alone.

Jason LaBar : Bryan was very shocked by his arrest. … Bryan did not know why they were there, but he was aware of the case in Idaho.

Monroe County public defender Jason LaBar represented Kohberger in Pennsylvania as he was awaiting extradition to Idaho.

Jason LaBar : Bryan indicated to me that he was eager to be exonerated — that he was willing to go back to Idaho.

On Jan. 3, at a hearing in Pennsylvania, Kohberger signed his waiver of extradition. And on Jan. 4, was flown to Idaho, where he is in jail, charged with the four murders.

On Jan. 5, Kohberger appeared in court in Moscow with his new public defender to hear the charges read against him. He has yet to enter a plea.

JUDGE MEGAN MARSHALL:  The maximum penalty for this offense if you were to plead guilty or be found guilty is death or imprisonment for life. Do you understand?   

BRYAN KOHBERGER: Yes.

That same day, that affidavit was released that laid out startling new details about the murder investigation. According to the affidavit, one of the surviving roommates actually saw the murderer and stood in a "frozen shock phase."  She is referred to as DM in the affidavit, and told police that earlier, she heard a female voice say, 'something to the effect of  "there's someone here." And later, a male voice say, "something to the effect of "it's ok, I'm going to help you." Later she opened her door "… after she heard crying and saw a figure clad in black clothing and a mask..." She described the figure as "5'10'… with bushy eyebrows."

The affidavit states that, according to DM, the male walked toward the back sliding door and DM locked herself in her room. It was later in the morning when that call was made to 911 from one of the surviving roommate's phones, to report an unconscious person. It is unclear what occurred in the hours before police were called. It is believed the murders took place between 4 and 4:25 a.m. Police say they discovered, on the bed in Madison's room, a knife sheath with a Marine insignia.

James Gagliano : I would imagine that a — crime scene as — as grisly and ghastly as this one — that there would have been … DNA left by the perpetrator.

According to the affidavit, the knife sheath was processed and "the Idaho State Lab later located a single source of male DNA on the button snap."  They were able to link it to DNA recovered from the trash at the Pennsylvania Kohberger family home.

It is not clear, what, if any, connection Kohberger had with the victims. However, the affidavit states that by using cellular phone data, police were able to place Kohberger's cell phone near the crime scene "on at least twelve occasions before November 13, 2022. All of those occasions, except for one, occurred in the late evening and early morning hours …"

Even with these new details, many question remain. A newly issued gag order prohibits officials and others involved in the case from speaking about the murders. Also, authorities have sealed a search warrant that was carried out at Kohberger's home in Pullman, Washington.

Jim Gagliano : This is one where you don't want a mistake. You don't want something to happen during this process that's going to give the alleged suspect an opportunity to beat the case.

Now, the case will work its way through the court system as parents, who lost their children, will be looking for answers.

Steve Goncalves : We find the truth, you know. You get the truth, and then that — that'll — that'll be everything.

IN REMEMBRANCE

You can see it in the stunned, silent faces of the kids. Faces that ask "why?" without even speaking. 

Young eyes glisten, bathed in the glow of candlelight at a vigil held for the young lives lost.  A ritual all too familiar across America. The flowers, the prayers, the vows to carry on. In Idaho, they hold on tight to each other and to the memories of those loved and lost.

EMILY (memorial service): Life is so unfair and unpredictable (crying).

For Xana Kernodle's friend Emily, the wound remains raw.

EMILY (memorial service): And it tears me apart knowing I can't hug her. (Crying) So hold those you love closer. Hug them a little tighter and tell 'em you love them. We'll find justice for you, Ethan, Maddie, and Kaylee. We love you all so much.

And for Ashlin, Maddie Mogen's memory is still vibrant.

ASHLIN (memorial service): You truly will live on forever -- not only in my heart, but in the heart of so many people that were impacted by your beautiful smile, your grace, your patience, your open heart, and your craziness.

Hunter Johnson remembers a pal he could rely on — Ethan Chapin.

HUNTER JOHNSON (memorial service): Ethan was always someone you could count on to make you smile and — cheer up your mood. … And I — feel so lucky to have shared so many great memories with him (emotional).

But those who are older perhaps sense that pain that runs this deep, never goes away. Kaylee's father, Steve Goncalves.

Steve Goncalves : You don't heal from somethin' like this. … it's never gonna happen. You're never gonna be healed. You're never gonna get through this. And when they die, part of you dies.

Steve Goncalves : We're tired of all these types of crimes. We're tired of all this stuff. And — we can rally around these terrible tragedies, and … We're hopin' that as a society we come back stronger. And we — we decide to not let this be accepted anymore, you know. That's what I hope for.

Bryan Kohberger's next court appearance is scheduled for Jan. 12.

He will have a chance to enter a plea at a later date.

Arrest in Idaho Killings What We Learned From Authorities After Arrest in Idaho Killings

The charging of a suspect was the first major break in the case of four young people that were stabbed to death in Moscow, Idaho, in November. The suspect was charged with first-degree murder and felony burglary.

A criminology student was charged in four University of Idaho killings, though the police gave no motive.

MOSCOW, Idaho — The police arrested a 28-year-old criminology student on Friday and charged him with murder in the brutal killing of four University of Idaho college students who were found stabbed to death overnight in a home near their campus last month.

The man, Bryan C. Kohberger, was taken into custody at his parents’ home in Effort, Pa., where it appeared he had been staying recently, according to Michael Mancuso, an assistant district attorney in Monroe County, Pa.

Mr. Kohberger was pursuing a Ph.D. in criminal justice and criminology at Washington State University, which lies about 10 miles from Moscow, Idaho, where the murders took place. He recently entered the program after graduating in June from DeSales University in Center Valley, Pa., with a master’s degree in criminal justice.

Mr. Kohberger was charged in Idaho with four counts of first-degree murder and was being held without bail in Pennsylvania. An extradition hearing has been scheduled for Tuesday.

“These murders have shaken our community, and no arrest will ever bring back these young students,” the Moscow police chief, James Fry, said at a news conference. “However, we do believe justice will be found through the criminal process.”

The arrest of Mr. Kohberger came nearly seven weeks after the college students were stabbed to death on Nov. 13 in a crime that horrified the small Idaho college town and prompted many students to stay home and finish classes online after Thanksgiving break. Residents had grown increasingly frustrated in recent weeks as a killer remained on the loose, and one victim's father had begun to publicly criticize investigators.

The police declined to say anything about the suspect’s possible motive, and they said that a long knife they believe was used to carry out the attacks had not been found. But the arrest of a criminology student added another unsettling element to an already macabre case.

The students who were killed — Madison Mogen, 21; Kaylee Goncalves, 21; Xana Kernodle, 20; and Ethan Chapin, 20 — were attacked in at least two separate bedrooms, probably as they slept. The three women lived at the rental house where the attack occurred, while Mr. Chapin was visiting Ms. Kernodle, his girlfriend. Two more roommates apparently slept through the stabbings and did not wake up until several hours afterward.

The police had in recent weeks been searching for the driver of a white Hyundai sedan that they said had been spotted near the victims’ home on the night of the killings. Chief Fry said on Friday that the police had found a car matching that description.

In a post on Reddit from about seven months ago, a user who identified himself as Bryan Kohberger asked people who had spent time in prison to take a survey about crimes they had committed. The survey listed Mr. Kohberger as a student investigator working with two colleagues at DeSales, and it asked respondents to describe their “thoughts, emotions and actions from the beginning to end of the crime commission process.”

B.K. Norton, who was in the same graduate program as Mr. Kohberger, said that he continued attending classes after the killings had occurred and seemed more animated at that time than he had been earlier in the semester.

“He seemed more upbeat and willing to carry a conversation,” Ms. Norton said in an email. She said Mr. Kohberger was interested in forensic psychology.

Ms. Norton said Mr. Kohberger’s quiet, intense demeanor had made people uncomfortable, as had comments he made against L.G.B.T.Q. people.

“He sort of creeped people out because he stared and didn’t talk much, but when he did it was very intelligent and he needed everyone to know he was smart,” Ms. Norton said.

At Mr. Kohberger’s apartment complex in Pullman, Wash., on Friday, several neighbors said they were left unsettled after learning that the suspect had been living so close by and regretted regularly leaving their doors unlocked in the quiet housing development on campus. The complex includes about a dozen apartment buildings, and a children’s playset sat behind the unit where Mr. Kohberger had been living.

Andrew Chua, a graduate student who lived in the same building as Mr. Kohberger, said he briefly met him in August or September. The two spoke about their degrees and where they were from, and Mr. Kohberger had appeared to be excited to continue his studies.

“He was really passionate about what he was doing,” said Mr. Chua.

Another graduate student who knew Mr. Kohberger said he was keenly interested in studying policing. But the student, who spoke on condition of anonymity because of worries about upsetting others in the department, said Mr. Kohberger had few friends at the school. Mr. Kohberger had appeared to want to socialize, the student said, but had made offensive remarks in the past that had left him somewhat isolated.

Students at Washington State University frequently socialize with students from the University of Idaho, which is a 15-minute drive across the state line.

Before moving to Pullman, Mr. Kohberger had spent much, if not all, of his life in the Pocono Mountains region of Pennsylvania.

Casey Arntz, who was one year ahead of Mr. Kohberger at Pleasant Valley High School, said he was known to have a temper and that he did kickboxing, possibly as a way to get his anger out. She said his mother had sometimes worked as a substitute teacher at the high school.

Ms. Arntz, 29, said that she used to occasionally hang out with Mr. Kohberger as part of a group, once hiking a mountain near her parents’ house, but had not seen him since a friend’s wedding in 2017.

According to articles in local newspapers , Mr. Kohberger worked for several years as a security officer with the Pleasant Valley School District, drawing some attention in 2018 for helping another officer save the life of an employee who was having an asthma attack. He left the district in the summer of 2021.

On the night of the killings, the four Idaho students had all spent the night out with friends. Mr. Chapin and Ms. Kernodle attended a party at the Sigma Chi fraternity nearby, while Ms. Mogen and Ms. Goncalves went to a bar called the Corner Club. All four students returned to the home shortly before 2 a.m.

From 2:26 to 2:52 a.m., seven unanswered phone calls were made from Ms. Goncalves’s phone to a former boyfriend. Several calls were also placed to the same man from Ms. Mogen’s phone, the police said. The former boyfriend had not answered the phone because he was sleeping at the time, Ms. Goncalves’s older sister later said.

When the two surviving roommates woke up, they called friends to the house because they believed that one of the women who lived upstairs “had passed out.” When the friends got there, someone in the group called 911 just before noon, and the police arrived to find the victims and what the coroner later described as a bloody scene.

Mr. Chapin’s family welcomed the arrest in a statement on Friday and also acknowledged the long process of grieving that remains ahead for them and other victims’ families.

“We are relieved this chapter is over because it provides a form of closure,” the Chapin family said. “However, it doesn’t alter the outcome or alleviate the pain.”

Ms. Goncalves’s father, Steve Goncalves, who had at one point called the police “cowards” for not releasing more information, commended the police in an interview with Fox News on Friday and said it was the first good news he had heard in some time.

“You can’t even smile, when you have this over your head,” Mr. Goncalves said. “And it feels like a little bit of weight has been relieved.”

Erin Staheli, who has lived in Moscow for about three years and delivers food for DoorDash, said she started crying out of relief when she heard news of the suspect’s arrest. She said she and her boyfriend, who also delivers food for DoorDash, had noticed an increase in orders in the weeks since the crime, which she believed was because people were afraid to go outside.

“It’s been just really scary,” Ms. Staheli said. “Everybody is freaked out.”

At the news conference on Friday, Chief Fry was asked whether the community was safe after so many weeks of fear.

“We have an individual in custody who committed these horrible crimes, and I do believe our community is safe,” he said. “But we still do need to be vigilant, right?”

B.K. Norton, who was in the same graduate program as Bryan Kohberger, said she “could always sense that something was off” with him. “He sort of creeped people out because he stared and didn’t talk much, but when he did it was very intelligent and he needed everyone to know he was smart,” she said. After the murders, Kohberger was back on campus, she added, and seemed more upbeat.

The F.B.I. has assigned 60 personnel and two behavioral analysts to help the small Moscow Police Department with the investigation. Dennis Rice, an F.B.I. special agent in charge in Salt Lake City, said the bureau was committing its full support “in an effort to solve this horrific case and bring some resolution for the victims' families."

According to articles in local newspapers , a man named Bryan Kohberger worked for several years as a security officer with the Pleasant Valley School District in eastern Pennsylvania, drawing some attention in 2018 for helping another officer save the life of an employee who was having an asthma attack. He reportedly left the district in the summer of 2021.

Steve Goncalves, whose daughter Kaylee was among the victims, told Fox News that news of Bryan Kohberger's arrest felt “like a little bit of weight has been relieved,” and that “Of course he's innocent until proven guilty, but that's a lot better off than we were 48 hours ago.” He added that the arrest eased the family's worries that the perpetrator might show up at a celebration of life that was held today for Kaylee and another victim, Madison Mogen.

A fellow graduate student in criminology at Washington State University said that Bryan Kohberger was keenly interested in studying policing. The student, who spoke on condition of anonymity because of worries about upsetting others in the department, said Kohberger had few friends at the school. He appeared to want to socialize, the student said, but had made offensive remarks in the past that had left him somewhat isolated.

Washington State University, where Bryan Kohberger was a graduate student, said its Police Department assisted Idaho law enforcement in executing search warrants on Friday at Kohberger's apartment and office, which were both on its campus in Pullman, Wash. The campus is less than a 15-minute drive from the site of the killings in Moscow, Idaho. The university provost, Elizabeth Chilton, said in a statement that the university hoped “the announcement today will be a step toward healing.”

Bryan Kohberger, who was charged with murder in the Nov. 13 killings of four Idaho students, completed his first semester as a Ph.D. student in criminal justice this month, Washington State University said in a statement. According to the university's website, the last day of lectures was Dec. 9, and the last day of exams was Dec. 16.

Here’s what we learned from the authorities after a suspect was arrested in the Idaho killings.

The police in Moscow, Idaho, held a news conference on Friday after the authorities announced that a 28-year-old man had been arrested in the brutal killing of four University of Idaho students.

The arrest was the first major break in the case after weeks of growing frustration in the rattled community.

Here’s what the authorities did, and didn’t, reveal during the news conference:

The suspect, Bryan C. Kohberger, was charged with four counts of first-degree murder and one count of felony burglary, “which involves entering the residence with intent to commit the crime of murder,” said Bill Thompson, the top prosecutor in Latah County, Idaho.

Mr. Kohberger, a Washington State University graduate student, was arrested in Pennsylvania at his parents’ home and denied bail as he awaited an extradition hearing set for Tuesday afternoon. He had an apartment in Pullman, Wash., the Idaho prosecutor said.

The Moscow police chief, James Fry, declined to identify a possible motive for the killings and did not give details on how the authorities came to suspect Mr. Kohberger. A probable cause affidavit, which would generally contain the police’s justification for an arrest, is sealed under Idaho law until the suspect has returned to the state, the police and top prosecutor said.

Chief Fry said the police had not yet found a murder weapon, but confirmed that they found a white Hyundai sedan that they believe is connected to the case. He also said that while the home where the students were killed was scheduled to be cleaned on Friday after investigators finished collecting evidence, that process was halted midday because of “a legal request from the court.”

In response to a question about whether law enforcement was still searching for other suspects, Chief Fry said: “We have an individual in custody who committed these horrible crimes, and I do believe our community is safe,” adding, “but we still need to be vigilant.”

The police said they received more than 19,000 tips on the case, and they reiterated a request for the public to come forward with any information.

Gov. Brad Little said the arrest was welcome news and “an important step in bringing peace to a community, state, and nation gripped by this horrifying tragedy.”

Moscow had not recorded a murder in seven years.

Moscow is a community of about 25,000 people on the Washington State border, and the university has 11,000 students.

The city had not recorded a murder in more than seven years. Students said in interviews that they normally felt safe walking around town late at night or leaving bikes unlocked around campus. But after the killings, many students left campus early for Thanksgiving break, worried about an apparent killer on the loose.

Some students who remained have started taking more precautions and walking around in groups. A coffee shop told patrons it was closing early so that employees could get home before dark.

After the arrest of a suspect on Friday, Police Chief James Fry said he believed Bryan Kohberger, a 28-year-old Ph.D. student at Washington State University, committed the crimes and added, “I do believe our community is safe.”

The Idaho police declined to give any details about a possible motive for the killings at the news conference, and did not comment on how they came to suspect Kohberger. They’ve asked members of the public with any information about him to come forward.

Andrew Chua, a Washington State University graduate student, said the suspect, Bryan Kohberger, lived in the same graduate student apartment building as him in Pullman, Wash. The two spoke only briefly, discussing their degrees and where they were from. “He was really passionate about what he was doing,” Chua said.

The family of 20-year-old Ethan Chapin, one of the four victims, issued a statement saying they were “relieved this chapter is over.” The family said that they had learned that a suspect had been identified from the authorities last night and that they were grateful to the police for their work. “If we all lived and loved as Ethan did, the world would be a better place,” the relatives said.

Chief James Fry has concluded the news conference, in which the authorities announced the arrest of Bryan Kohberger, a 28-year-old Ph.D. student at Washington State University, who has been charged with four counts of murder. Chief Fry declined to release much information, but did say that the suspect, who was arrested in Pennsylvania, has an apartment in Pullman, Wash. He also said that the police had not yet recovered a murder weapon.

The police have not recovered a murder weapon, Chief Fry says. The authorities have said they believe the suspect used a long knife to carry out the four fatal stabbings.

The Moscow police chief, James Fry, declines to identify what motive the suspect may have had in carrying out the killings.

The home where the students were killed was scheduled to be cleaned today after investigators had finished collecting evidence. However, that process was halted midday, Chief James Fry said, because of “a legal request from the court.” He did not elaborate.

Asked if the community in Moscow, Idaho, is safe, Chief James Fry says he believes the man in custody committed the crimes and adds, “I do believe our community is safe.”

C. Scott Green, the president of the University of Idaho, says the arrest “is a relief to our university, our community and our extended Vandal family.” (The university's mascot is the “Vandal” and its students, alumni and sports teams are often referred to that way.)

“This is not the end of this investigation — in fact, this is a new beginning,” said Bill Thompson, the top prosecutor in Latah County, Idaho. He pleaded with the public to contact authorities if they know anything about the suspect, Bryan Kohberger.

Kohberger, the man charged with murdering four University of Idaho students, has an apartment in Pullman, Wash., the prosecutor says.

Bryan Kohberger, a 28-year-old Ph.D. student at Washington State University, has been charged with four counts of first-degree murder as well as felony burglary, “which involves entering the residence with intent to commit the crime of murder,” says Bill Thompson, the top prosecutor in Latah County, Idaho.

Frustration had grown in recent weeks — both in Moscow and among some victims’ families — as more than seven weeks passed with no suspect identified. Chief Fry says that he understands that frustration, and that the investigation was complex and required extensive work by detectives, crime lab employees and many others.

“These murders have shaken our community, and no arrest will ever bring back these young students,” says James Fry, the police chief in Moscow, Idaho. But, he vows, justice will be found in the criminal justice system.

Chief James Fry of the Moscow Police Department sounds as if he is choking back tears as he announces the arrest of Bryan Kohberger, a Washington State University graduate student, in connection with the killing of four University of Idaho students.

The authorities have divulged limited details of the killings.

Investigators have said that the four victims were killed early on Sunday, Nov. 13, but they have not specified a time.

All four were probably asleep at the time they were attacked and may have been in their beds, according to Cathy Mabbutt, the Latah County coroner. She said that all four appeared to have been stabbed multiple times with a large knife and that some of the victims probably tried to fight back.

“It’s such a horrific crime,” Ms. Mabbutt said. “It’s hard to think that somebody, whether they live here or they were here, commits something like that and is at large.”

None of the victims showed signs of sexual assault, Ms. Mabbutt said.

At a vigil at the University of Idaho after the killings, Ms. Goncalves’s father, Steve Goncalves, said that his daughter and Ms. Mogen, who had been close friends since sixth grade, were killed in the same bed, a detail the police would not confirm.

While the four friends were being killed, two other female housemates were in the house but were not attacked.

Investigators suggested that those two had slept through the killings. The house has six bedrooms, with two on each floor. The police said the victims were found on the second and third floors.

When the two surviving housemates woke up, they called some of their friends to the house because they believed that one of the women who lived upstairs “had passed out and was not waking up.” After the friends arrived, someone from the group called 911 just before noon, and the police arrived to find the victims. Investigators have declined to release a recording or transcript of the 911 call.

The police said the two surviving housemates had each been out of town, separately, on Saturday and had returned to the house by about 1 a.m.
