Idaho murders: Police bringing cleaning crew to crime scene

Police in Moscow, Idaho, say they're sending in a cleaning crew to the house where four University of Idaho students were mysteriously murdered.

"Starting Friday morning we're going to be bringing in a professional cleaning crew to go to the residence," Moscow Police Chief James Fry said in a video statement Thursday. "Part of the reason we're doing that is because of the biohazards, as well as chemicals that were used during the investigation."

Moscow police said there's "no timeline for completion" of the cleaning "but the property will be returned to the property management company when finished."

Roommates Kaylee Goncalves, Madison Mogen and Xana Kernodle, as well as Kernodle's boyfriend, Ethan Chapin, were all stabbed to death in the girls' off-campus house in the early hours of Nov. 13.

No suspects have been identified.

Two other roommates -- who police said are not suspects -- survived and likely slept through the murders, according to officials. The survivors were on the ground floor while the four victims were on the second and third floors.
