Idaho police are now saying there is "possibly" still a threat to the Moscow community after four students were murdered in their home near the University of Idaho on the morning of Nov. 13.
Police are still looking for persons of interest or suspects in the murders, and no one is in custody as of Wednesday afternoon.
"We do not have a suspect at this time, and we cannot say there is no threat to the community," Moscow Police Department Chief James Fry said during a Wednesday afternoon press conference.
Police said earlier this week that there was no threat, citing evidence from their preliminary investigation indicating that the killings were "an isolated, targeted" incident.

Police on Sunday responded to initial reports of an unconscious person on King Road — adjacent to Greek Row — around noon and found the four deceased students upon arrival. Officers stationed outside the home this week described a bloody scene inside.
There were no signs of forced entry, and the door of the home was still open when police arrived on Sunday, Fry said Wednesday.
