Bryan Kohberger faced emotional statements from victims' families in Boise courtroom, including scathing rebukes and one offer of forgiveness before receiving life sentences.

Though the motive behind Bryan Kohberger's violent attack remains unknown, the former police chief says "new information could come out still."

The family of Kaylee Goncalves, one of the four University of Idaho students killed by Bryan Kohberger in 2022, railed against him as a “joke,” a “loser,” and “as dumb as they come” in a day of searing victim impact statements.

Following Kohberger's life sentence, Moscow Police releases documents showing brutality of crime, police scanner searches and accounts of strange behavior.

Gilbertson and lead prosecutor Bill Thompson opened up about their theories on who was targeted and the investigative process, including an interview with Kohberger. Gilbertson walked ABC News through the horror found at 1122 King Road on Nov. 13, 2022, where Kaylee Goncalves, Maddie Mogen, Xana Kernodle and Ethan Chapin were stabbed to death.
