Bryan Kohberger, 30, is charged in the murders of Madison Mogen, 21; Kaylee Goncalves, 21; Xana Kernodle, 20; and Ethan Chapin, 20.

The grieving family of 21-year-old Kaylee Goncalves spent weeks waiting for an arrest in her killing. Since then, they and relatives of the three other University of Idaho students fatally stabbed on a late 2022 night in their off-campus home have endured a legal process punctuated by delay after delay.

Prosecutors amassed a mountain of damning evidence and key legal victories against Bryan Kohberger in the weeks before they offered him a plea deal for the 2022 murders of four University of Idaho students.
