The audio of a 911 call made on the day four University of Idaho students were stabbed to death reveals confusion as the callers realized at least one student was not waking up.

Madison Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20, and Ethan Chapin, 20, were stabbed to death in the early morning hours on Nov. 13, 2022 in Moscow. Two other female roommates were home during the attack but were not harmed. Chapin was in a relationship with Kernodle and spent the night at the residence.
