Elite FBI unit joins probe into University of Idaho murders, students remembered

An elite Federal Bureau of Investigations unit has joined the search for the suspect who allegedly killed four University of Idaho students on early Sunday morning.

Four University of Idaho students, Ethan Chapin, 20; Xana Kernodle, 20; Madison Mogen, 21; and Kaylee Goncalves, 21, were killed inside a King Street home in Moscow, Idaho between the hours of 3 and 4:00 a.m. on Sunday, according to Moscow Mayor Art Bettge.

Police found the four deceased students while responding to an unconscious person call on Sunday at 11:58 a.m.

Officials said on Tuesday in a press release that the suspect used an “edged weapon such as a knife” in the attack against the students. Investigators believe that the incident was “an isolated, targeted attack” with “no imminent threat to the community at large.”

Coroner Cathy Mabbutt told Fox News that the same knife was likely used as the weapon in killing all four victims.

A spokesperson for the Federal Bureau of Investigations told Fox News Digital on Thursday that its Behavioral Analysis Unit is assisting local law enforcement officials in the case.

The unit performs “crime analysis, profiles of unknown offenders, investigative suggestions, threat assessments, interview strategies,” and “critical incident analysis.”

Jackie Fisher, owner of the Mad Greek Restaurant, where both Mogen and Kernodle worked, told Fox News Digital that she’s deeply saddened by the incident.

“All I can say right now is that we’re just all deeply saddened by the loss of both Maddie and Xana, they were wonderful workers. They’ve been here for a couple of years with me,” Fisher said. “All of the employees are just shook right now, I think as well as the rest of the Moscow community.

A memorial service for Chapin is scheduled for Nov. 21. An obituary is encouraging attendees to wear blue, which “was Ethan’s triplet color.”

During Wednesday’s press conference, Moscow Police Department Chief James Fry said that two roommates were inside the house when the four victims were killed on early Sunday morning.

The two roommates were “unhurt,” according to Fry, who didn’t add if the individuals were witnesses to the attack.

Police haven’t identified a person of interest or any suspects as of Wednesday night, and Fry did not rule out an ongoing threat to the community.

“We do not have a suspect at this time, and we cannot say there is no threat to the community,” Fry said. “There is a threat out there, possibly.”

“We need to be vigilant. We need to watch out for our neighbors,” Fry said.

Latah County Prosecutor Bill Thompson told NBC News on Thursday that it’s possible there’s more than one suspect.

“It certainly is possible. That’s the purpose of the investigation, that’s why we’re really hoping for any information from the public that can help the investigators recreate everyone’s activities from Saturday night into early Sunday morning and hopefully give them the leads, the information, to identify who did this,” Thompson said.

Mogen and Goncalves were both seen on a Twitch stream at a local food truck in Moscow, Idaho, shortly before they were killed at the King Road residence near the University of Idaho campus.

Anyone with information about the incident is being asked to call Moscow police at 208-883-7054.
