Authorities have publicly released the chilling 911 call made by the surviving roommates of four University of Idaho students who were brutally killed in an off-campus home in 2022.

A woman told the dispatcher that one of the roommates was "not waking up" and that a man had been seen at the house in the night.

“It’s torture,” Steve Goncalves, whose 21-year-old daughter, Kaylee Goncalves, was killed at a rented house in Moscow, Idaho, on Nov. 13, 2022, said in an interview with NBC News. Three other University of Idaho students were also found stabbed to death: Madison Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20.
