“We are reviewing the video we obtained, but we ask citizens to contact us with any information that could be useful in this investigation,” he added.
The University of Idaho canceled classes on Monday but have since resumed, according to Scott Green, the university’s president.
“A number of our students want to go to class,” Green said Wednesday. “They feel comfortable with the other students. They feel comfortable interacting and keeping busy with their faculty and attending lectures, workshops; some are working on their semester projects, from what we’ve learned.

Police: Two housemates were in the house during the killings
As the investigation proceeds, police have begun to trace a timeline of what happened in the hours leading up to the murders.
Chapin and Kernodle were at a party on campus Saturday night, while Mogen and Goncalves were at a downtown bar before everyone went home early Sunday morning, shortly after 1:45 a.m., Fry said.

All four of the victims died early Sunday morning, Fry said, but there were no 911 calls until noon. All four victims were stabbed with a knife, he added.
The police chief did not reveal who called 911, but said two other housemates were in the house at the time of the deaths, neither of whom were injured or taken hostage.
“We’re not just targeting them, we’re targeting anyone who may have been in and out of that residence,” he said.
The two housemates cooperated fully with law enforcement, Idaho State Police spokesman Aaron Snell told CNN Wednesday.
After calling 911 for an unconscious person, officers found the door to the house open and a gruesome crime scene inside.
There was no evidence of forced entry, Fry said. “We’re not 100% sure the door was open, but there was no damage and the door was still open when we arrived at the scene,” Fry said.

“It was quite traumatic to find four college students dead in a residence hall,” he said.
Mabbutt added that autopsies could provide more information about what happened.
“There might be some, you know, some evidence about suspicion that we get in autopsies that is helpful,” Mabbutt said.
