MOSCOW, Idaho – Two weeks have passed since four University of Idaho students were stabbed to death in an off-campus rental house, and police have no suspects.
Kaylee Goncalves, 21; Madison Mogen, 21; Xana Kernodle, 20; and Ethan Chapin, 20, were found dead in a house a few meters from campus, hours after police said someone attacked them in their sleep on November 13. The three women lived there and Chapin was visiting his girlfriend, Kernodle.
Investigators have conducted more than 150 interviews and received more than a thousand tips in the case so far, said Aaron Snell, director of communications for idaho state police. But they’re asking anyone who knows anything to come forward, even in minute details.
“At this point, we haven’t ruled anything out,” he told Fox News Digital. “We look from all angles”
Chapin was a member of the Sigma Chi fraternity, specializing in recreation, sports and tourism management, the University of Idaho said. His fraternity is across a field about 200 yards from the crime scene.
Both Kernodle and Mogen were part of the Pi Beta Phi sorority and were marketing majors. Goncalves, major of general studies, belonged to Alpha Phi.
Two of the victims slept on the second floor and two on the third, but police have not confirmed who was found where – or whether the bedroom doors were locked after the killings.

The Latah County coroner later said all four were victims of stabbing homicide – and their injuries were likely inflicted while they slept. “Some” of them showed signs that they fought back, but police declined to give further details.
Two roommates, who slept on the ground floor, were not attacked. There was also no pet dog at home.
The police say it was an “isolated and targeted” attack, but they have kept most details under wraps as they continue to search for their suspect.
So far, investigators have obtained more than 260 videos of community members taken the night of the murders. They surveyed the area and conducted a grid search on the wooded hill behind the house. They collected DNA, fingerprints and additional evidence from the crime scene. And they pulled data from cell towers, in addition to other metrics.
“We use all the techniques that are available to us,” Snell said. “And we will continue to investigate all potential leads.”
John Kelly, a criminal profiler and psychotherapist with experience interviewing serial killers, said due to the lack of publicly available details, he is “up in the air” on whether the attacker was a random stalker or someone who knows the inside of the house.
But one thing is clear, he says. “He’s really, really a savage, with no care or empathy or anything like that,” he told Fox News Digital.
Police, deputies, the county attorney and the FBI worked until Thanksgiving trying to find answers in the murder mystery. They are asking anyone with information about the case to get in touch.
“We’re looking at all angles,” Snell said. “Our concept is that if we start to lock ourselves into a specific idea, we may miss other guidance in other elements of this investigation.”
