ABC News sat down with Idaho State Police Lt. Darren Gilbertson, the lead detective in the Idaho murders case, after Bryan Kohberger was put behind bars for life.

Hundreds of pages of previously sealed documents were made public by the Moscow Police Department, but information is still redacted.

Idaho prosecutor Bill Thompson says whether Bryan Kohberger received life in prison or the death penalty, Kohberger will “be in prison until he dies.” NBC News’ Liz Kreutz asks Thompson how the plea deal in the University of Idaho murder case came to be.
