 Ethan Chapin, Zanna Cornodle, and Madison Mogan were fatally stabbed overnight November 13, 2022, at a home off the school's main campus in Moscow. Koberger was arrested December 30 in his home state of Pennsylvania. The case has been slow to progress over a series of pretrial motions and hearings about evidence, alibi, and a gag order. Koberger faces four charges of first-degree murder and a felony burglary count. If convicted, he could face the death penalty.
