Two roommates were at the Moscow, Idaho home while four University of Idaho students were killed on early Sunday morning, but didn't call 911 to report the incident until around noon, according to Moscow Police Department Chief James Fry.

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

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

In a press release on Tuesday, police said that the suspect used an "edged weapon such as a knife" in the attack, adding that investigators believe the incident was "an isolated, targeted attack" with "no imminent threat to the community at large."

Fry said in a press conference on Wednesday evening that two roommates were inside the home during the attack.

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

Idaho State Police spokesperson Aaron Snell told Fox News Digital after the press conference that Fry didn't misspeak.

"Chief Fry’s comment was not misspoken," Snell said. "As there is a suspect outstanding, there remains a threat. However, it is believed this was a targeted incident."
