Idaho police now say after killing of college students, no arrest: 'Cannot say there's no threat'

Police in Moscow, Idaho, after saying the killing of four college students over the weekend was an isolated incident, are now saying they "cannot say there's no threat."

Moscow Police Chief James Fry said Wednesday at a press conference that law enforcement still believes that the killings Sunday at an off-campus residence was isolated but "we cannot say that there's no threat to the community." 

"We do not have a suspect at this time, and that individual is still out there," Fry said.

He also said two roommates were inside the residence at the time of the attack and that at least one called police.

Law enforcement said Tuesday that there was "no imminent threat to the community at large."

They also said the student were killed with a sharp object like a knife.

Data shows that the town of 25,000 had not recorded a homicide since 2015, and Fry said his department has over 25 investigators on the case and the FBI and Idaho State Police are assisting.
