New court filings in the Idaho student murders case could severely handicap suspect Bryan Kohberger’s defense, according to legal experts – he allegedly purchased a Ka-Bar knife on Amazon months before the murders and then shopped for a replacement days after they took place.
Bryan Kohberger, a 30-year-old former criminology Ph.D. student, is accused of using a large, bladed weapon to kill four University of Idaho undergrads – Madison Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20 and Ethan Chapin, 20.

According to Latah County Coroner Cathy Mabbutt, all four victims died with multiple stab wounds. At least two of them were so intoxicated at the time of the attack that they were unable to resist at all, prosecutors wrote in court filings.
Under Mogen’s body, police found a Ka-Bar knife sheath, stamped with a United States Marine Corps logo and allegedly containing Kohberger’s DNA on the snap.

Prosecutors revealed in court filings this week that he allegedly bought a Ka-Bar, a sheath and a sharpener on Amazon in March 2022, months before the murders. Then, in the weeks after the murders, his Amazon app “click activity” allegedly shows he was browsing for a replacement.

Experts say the shopping list will be difficult for the defense to explain away, especially based on the timing and the specific details about what Kohberger was allegedly looking at.
That is a catastrophic fact for his defense.
— Edwina Elcox, Boise defense lawyer
“There’s always kind of this lore around that using a knife in a murder is particularly personal,” said Edwina Elcox, a Boise defense attorney who has been following the case. “And then the time frame of the search that links him, if this is correct, to this murder weapon shows a significant level, or at least I’m sure the prosecution would argue, shows a significant level of premeditation.”
She said that the slate of newly revealed evidence against Kohberger indicates prosecutors may have a stronger case than previously known.

IDAHO COURT RELEASES SURVIVING ROOMMATES’ TEXT MESSAGES FROM NIGHT OF STUDENT MURDERS
Kohberger’s defense team has asked the court to keep his Amazon records out of the trial.
“The information that is publicly available is that …the murder weapon, other than the sheath, has never been recovered,” Elcox told Fox News Digital. “And then he is searching for this very, very specific item. This is beyond a catastrophic fact to the defense…I do not know how you explain that away.”

For Joseph Giacalone, a retired NYPD sergeant and cold case investigator, the Amazon business records are yet another tool in the digital era that he believes will increasingly help law enforcement solve crimes going forward.

“Electronic evidence is gonna bring this case to a head for sure – it’s amazing,” he told Fox News Digital. “I said cellphone records, internet records and video surveillance are things that are gonna solve most cases going forward, but having this type of information is extremely damaging.”

Prosecutors made the revelation in response to Kohberger’s defense team trying to have evidence of his Amazon activity kept out of the trial, arguing in part that the retail giant’s algorithm “shapes user behavior” by serving up items it predicts shoppers want.

“Applying the test for relevancy, first, Kohberger’s click activity which shows a purchase of a Ka-Bar knife and sheath before the homicides, makes it more probable (than it would be without the evidence) that the Ka-Bar sheath found at the crime scene was Bryan Kohberger’s,” Latah County Deputy Prosecutor Ashley Jennings wrote in a court filing made public Wednesday evening.
“Second, Kohberger’s click activity after the homicides makes it more probable (than it would be without the evidence) that Kohberger had a reason to search for a Ka-Bar knife and sheath after the homicides.”

“This is the smoking gun evidence in the case,” said Neama Rahmani, a former federal prosecutor in Los Angeles who has been following the case.

The DNA connects Kohberger to the crime scene, and his Amazon history undermines a defense theory that it could have been planted, he said.
“This was a big mistake by Kohberger, who was otherwise very careful about covering his tracks,” he added.

Kohberger was pursuing a Ph.D. in criminology at Washington State University, just 10 miles down the road from the University of Idaho crime scene.
“I think he fancies himself…as remarkably intelligent, but as somebody who has studied this field, you know that law enforcement and their searches cast a wide, wide net,” Elcox told Fox News Digital. “Having this in a searchable history format is…OK, you just have to wonder, I don’t think you’re maybe as smart as you thought you were.”

Prosecutors have also alleged they traced his car, a white Hyundai Elantra, to and from the crime scene, that an eyewitness saw a masked man inside the home just after the murders, and that phone records also corroborate their alleged timeline of events. But Kohberger was not identified as a suspect until more than a month after the slaying with the help of investigative genetic genealogy.
While legal experts say the Amazon history is damming evidence, it also raises new questions for people who study the criminal mind, a topic Kohberger himself had studied at the graduate level. Was a suspect looking to replace a missing sheath, after leaving one behind at the crime scene, or a budding serial killer taking steps toward another kill?

“I don’t think this killing was a one off – I think…whoever did this, they were likely to kill again,” Dr. Kris Mohandie, a criminal psychologist, told Fox News Digital. “If it was him, why would he kill like that unless he enjoyed it? Further, he was interested in serial killers.”
And although whoever committed the crime is believed to have taken steps to conceal their tracks, he added killers always make a mistake that catches up to them.

“I’ll guarantee you that scene didn’t have one fingerprint of his on it, nor did it have anyone else’s,” said John Kelly, a criminal profiler who has been following the case. “Because whoever did it wiped it down so well.”

BRYAN KOHBERGER DOESN’T WANT AMAZON SHOPPING LIST REVEALED AT TRIAL
While search warrants show police recovered knives after Kohberger’s arrest, none have been publicly identified as a potential murder weapon.
Kohberger’s trial is scheduled to begin Aug. 11 in Boise.

He could face the death penalty if convicted. A judge entered not-guilty pleas on his behalf at his arraignment in May 2023.
In San Francisco’s Sunset District, controversy continues over what to do with the Great Highway.
Friday, the newly-appointed supervisor for that district, Alan Wong, confirmed he is running to keep his job. He also shared that he would support a ballot measure that would bring cars back to the now-closed stretch of road. Some residents in the district already said they would be prepared to fight back against that ballot measure if it came to fruition.
This has been a politically tumultuous year for the Sunset District. In November of 2024, San Francisco voters narrowly approved Proposition K, which moved to close the highway along Ocean Beach to cars and to transform it into a park. In March of 2025, the stretch of road was permanently closed to cars, and in April, the area was officially reopened as Sunset Dunes Park. In September, voters recalled then-Supervisor Joel Engardio, with many in the campaign against Engardio expressing frustration with his support for turning the Great Highway into a park. In November, Mayor Daniel Lurie appointed Isabella “Beya” Alcaraz as the new supervisor for District 4, only to have her resign a week later amid growing questions about her actions as a small business owner.
At the start of December, Mayor Lurie swore in Alan Wong as his new appointee to serve as supervisor in District 4. Wong grew up in the Sunset, attended Lincoln High School, and has served as both an elected member of the San Francisco City College Board of Trustees and as a legislative aid to former supervisor Gordon Mar.

In an interview with NBC Bay Area on Friday, Wong shared that he has not hidden the fact that he voted no on Prop. K in the 2024 election. However, in his first three weeks in office, Wong said he set out to “have conversations with different constituent groups and listen to them” about the issues.
“After three weeks of listening and having these conversations, I believe that my values and how I voted before align with the majority of the district,” Wong said.
San Francisco Supervisor Alan Wong supports a ballot measure that calls for cars to return to the Great Highway.
“And as the district supervisor, I need to take a leadership role in representing the district that I am here to serve,” he continued.
Wong said he is now prepared to be one of the four supervisors supporting a ballot initiative to reopen the Great Highway to cars on weekdays.

Molly Rose, with Sunset Parent Advocates, worries that when Wong was listening to community voices over the past three weeks, some voices may have been left out.
“If he talked to the Sunset residents, he didn’t talk to me, and he didn’t talk to us– the family groups I am a part of,” Rose said.
“We are all very pro-park, we use it very heavily as a park,” she continued.
Rose said there are several hundred parents involved with her group. As a parent, Rose said her children love going to the park there.
“Sunset Dunes is the place where I take my kids to have a safe place to play,” she said.

Rose said that she has been asking for Wong to meet with her group, but has been waiting to hear back from his scheduling team.
Wong’s office confirmed that Rose is in touch with their office and that Wong’s scheduler is “actively coordinating a time” for them to meet.
“While I do think there is a very loud, anti-park contingent of people in the Sunset, I don’t think they’re the majority,” Rose emphasized.
NEW YORK — The NHL hits a roster freeze at 11:59 p.m. on Friday, so with defenseman Egor Zamula clearing waivers and being assigned to the American Hockey League, it left a roster spot open.
Forward Denver Barkey has been called up.
Drafted by the Flyers in the third round of the 2023 NHL draft, Barkey turned pro this season and has been impressive while skating primarily on the wing for Lehigh Valley of the AHL. The 20-year-old has 16 points (seven goals, nine assists) in 26 games for the Phantoms, primarily playing on the wing with center Lane Pederson and winger Alex Bump.
“I think right from the start, he’s played very well,” Flyers assistant general manager Brent Flahr recently told The Inquirer. “On the production side, he makes plays, he works, and the details are great. Such a smart player. He’s got to get stronger and build up his body to handle the grind and but so far, so good.

“Down there, he’s been arguably our best forward a lot of nights, and coaches love them plays, plays a lot. He’s certainly going in the right direction.”

Well, the direction now is east to New York City ahead of the Flyers’ matchup with the New York Rangers on Saturday afternoon (12:30 p.m., NBCSP). The kid from Ontario is in line to make his debut at the World’s Most Famous Arena.
“I call him like a little mini [Travis Konecny],” Flyers director of player development Riley Armstrong said of Barkey over the summer. “He’s all over the puck. He’s grimy when he doesn’t have the puck. He’s always working to get the puck back.
“He’s really good with his stick picking pockets, transitioning, and his eyes are up; I don’t think a little guy like that skating around, his head down, is going to last very long in the game.

“But when you watch him go into corners, and he’s not afraid of that, he’s quick to get in, he’s quick to get out.”
Some have questioned Barkey’s size at 5-foot-10, 173 pounds, but no one questions his grit, moxie, will, and determination. Last season, he notched 25 goals and 82 points in 50 regular-season games before adding another nine goals and 20 points in 11 postseason games for London of the Ontario Hockey League.
On June 1, he captained the Knights to the Memorial Cup championship despite suffering a high-ankle sprain in the OHL Final. In the finale of the Memorial Cup, against the projected No. 1 for this June’s draft, Gavin McKenna, and Medicine Hat of the Western Hockey League, Barkey drove play and scored a pair of goals.
A month later, he was at the Flyers development camp but did not participate. He did, however, try.
“[Barkey] always comes to me every morning, ‘Hey, do you think you can get me out on the ice?’ No, no, you’re done,” Armstrong said with a chuckle in early July.

The rest helped. He was again impressive at the Flyers’ rookie camp and in a game against their Rangers counterparts in early September in Allentown.
Barkey opened eyes with his speed, hockey IQ, puck possession and patience, and high-end passing ability. Looking completely healed from his high-ankle sprain, the forward used his quickness, leverage, and ability to win pucks to beat the defense at every turn and notched a goal.
It appears that his summer of eating Italian giant subs — Mike’s way, minus the onions — at Jersey Mike’s with his buddy, and former London teammate, Oliver Bonk, to add weight paid off. Phantoms coach John Snowden called him “a heck of a hockey player” in September.
“Continue to get bigger, stronger,” Barkey said of his summer plans at development camp. “It’s a big jump next year. I’m going to be playing against older men and strong guys. So, continuing to get stronger, faster, and I think the biggest thing is just using my brain and then finding a way to adjust. It’s a different game in pro.”
And Barkey has adjusted well to the pro ranks, skating on the wing of the Phantoms’ top line, which drives play and is relied on for offensive swings. His fellow winger, Bump, was actually the one many thought would be called up.

The kid from Minnesota, who led Western Michigan to the NCAA championship in April, was pegged by everyone, including The Inquirer, to break camp with the Flyers; however, he was sent down after a poor main training camp. After a slow start in Lehigh Valley, he now has 20 points (seven goals, 13 assists) in 26 games in Allentown.
With neither team shooting well from the outside at Climate Pledge Arena, the Redhawks outperformed the favored Huskies driving the ball to the paint in the second half, making more plays down the stretch to beat their city rivals for a second straight year.
