Two of the four University of Idaho students killed Sunday were last seen alive ordering from a late-night food truck in Moscow, Idaho, around 1:41 a.m., live on the truck Twitch live broadcast.
In the video, Madison Mogen and Kaylee Goncalves order $10 carbonara from Grub Truckers, then wait about 10 minutes for their food. If they wait, they can be seen chatting with each other, as well as other people standing next to the truck.
Joseph Woodall, 26, who manages the food truck, told CNN the two students did not appear to be in any difficulty or danger.
Moscow Police Chief James Fry said Wednesday that the food truck video provided a useful timeline of their final hours and that the quadruple murder remains unsolved with no suspects and no murder weapon, according to reports Investigators remained at the bloody scene Thursday.
The students – Mogen, Goncalves, Ethan Chapin and Xana Kernodle – were all found stabbed to death outside their shared school returned home Sunday afternoon, authorities said.
An employee at the Spokane County Medical Examiner’s Office told CNN that an autopsy has been completed and the results will be released when available. On Thursday, police released a statement from Latta County Coroner Cathy Mabbutt, listing the cause of death as homicide and the manner of death as stabbing. Autopsy details were not included.
The killings and lack of information from authorities have angered residents of Moscow, a city of 25,000 that has not seen a murder since 2015, according to state police data. Local police are working with the FBI and state police to hunt down a suspect.
Although no arrests or suspects have been made, Moscow police Initially described the killing as a “targeted attack” and said there was no threat to the public. In his first news conference on the case on Wednesday, Frye backed off some points.
“We can’t say there’s no threat to the community,” Frye said. “As we say, please remain vigilant, report any suspicious activity and be aware of your surroundings at all times.”
Some students left for the fall recess day, which began Monday.
“Everyone went home because they were afraid (there were no suspects) of getting caught,” student Nathan Tinno, who planned to leave after some classes on Friday, told CNN. “It must be uneasy.”
Investigators are still working to identify the suspect, Latta County Prosecutor Bill Thompson told NBC’s “Today Show” Thursday.
“We have had no one in custody and the police have not been able to determine who is responsible for these homicides,” he said.

Ethan Chapin’s father, Jim Chapin, issued a statement Wednesday calling on police to release more information about the killing.
“The lack of information from the University of Idaho and local police has only fueled false rumors and innuendo in the media and social media,” he said. “Silence further exacerbates our family’s pain following the murder of our son. To Ethan and his three dear friends killed in Moscow, Idaho, and all of our families, I urge officials to tell the truth, Share what they know, find the attackers, and protect the greater community.”
University President Scott Green said they had been working with police to release information to the public.
“We helped when asked and kept pushing for as much information as we could because we knew we couldn’t interfere with the important work of a good investigation,” he said in a statement Wednesday.

Police have begun to draw up a timeline of what happened in the hours leading up to the killing, although there are still many unknowns.
Chapin and Kernodle were partying on campus Saturday night, while Mogen and Goncalves were at a downtown bar before they all headed home early after 1:45 a.m. Sunday, Fry said.
All four victims were stabbed to death sometime early Sunday morning, but the 911 call wasn’t received until noon, Frye said. The person in charge did not say who called 911. The coroner’s release said the four were pronounced dead at noon.
Green said two other roommates were at home when they were killed, and neither was injured or held hostage. Idaho State Police spokesman Aaron Snell told CNN on Wednesday that the two roommates have been cooperating fully with law enforcement.
“There were other people in the home at the time, but we weren’t just concerned about them, we were concerned about everyone who might have come in and out of that residence,” Frye said.
After a 911 call came in about an unconscious person, officers found the house with its doors open and a grisly crime scene.
Fry said there was no evidence of forced entry. “We’re not 100 percent sure that the door wasn’t locked, there wasn’t any damage, and it was still open when we got there,” Fry said.
“There was a lot of blood in the apartment,” Mabut told CNN affiliate KXLY on Tuesday.
“The discovery of four dead university students in a residence is a very distressing scene,” she said.
