The deaths of four University of Idaho students found stabbed to death over the weekend have officially been ruled homicides, authorities said.
Latah County Coroner Cathy Mabbutt said the manner of death was a stabbing for all four people. The cause of death was murder, according to Mabbutt.
The victims are Ethan Chapin, 20; Madison Mogen, 21; Xana Kernodle, 20; and Kaylee Goncalves, 21, who police say were attacked with a “sharp weapon,” most likely a knife.

Mabbutt, who completed the autopsies on Wednesday, previously said the killings were not a murder-suicide. Toxicology reports are still pending. She said the same knife was likely used to kill all four victims.

Police have not recovered a weapon or publicly identified a suspect in the quadruple homicide, which has rocked the small town of 25,000.
Scott Jutte, manager of Moscow Building Supply, told the Idaho Statesman that police had come more than once asking if the store had sold Ka-Bar brand knives, which they don’t have. The combat knife looks similar to the one Rambo used, Jutte added.
Latah County Attorney Bill Thompson told NBC News that there may be more than one suspect.
“It’s certainly possible. That’s the purpose of the investigation, which is why we’re really looking forward to any input from the public that can help investigators recreate everyone’s activities from Saturday night through early Sunday morning and hopefully to give them the clues, the information, to identify who did this,” Thompson said.

At a press conference on Wednesday, Moscow Police Chief James Fry urged locals to “stay vigilant” as the “individual is still out there.”
Police encountered a gruesome scene at midday Sunday after responding to a 911 call from an “unconscious individual” at the King Road home where the victims and two roommates lived.

The roommates were home when the students were killed between 3 a.m. and 4 a.m., Fry said.
The FBI and the Idaho State Police are assisting in the investigation.
