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.

"Chief Fry’s comment was not misspoken," Idaho State Police spokesperson Aaron Snell told Fox News Digital in a statement. "As there is a suspect outstanding, there remains a threat. However, it is believed this was a targeted incident."
