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.

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.

The family of Kaylee Goncalves has released a statement in response to newly released documents detailing the University of Idaho murders and the investigation into Bryan Kohberger.

What matters ultimately is the way the person was held accountable,” former U.S. Attorney Josh Hurwit, with the District of Idaho, told the Idaho Statesman.

Families of the University of Idaho murder victims spoke directly to their children's admitted killer Bryan Kohberger at his sentencing hearing.

One victim told friends she had a “stalker” and in the weeks before the killings reported seeing a shadowy figure while walking her dog, new documents say.
