Idaho killer Bryan Kohberger exhibited questionable behavior while behind bars at the Latah County Jail in Moscow, prior to his murder conviction.

According to report by Cpl. Brett Payne of the Moscow Police Department, Kohberger’s cellmate said the killer would take “45 minutes to an hour in the shower”  and wash his hands “dozens of times” daily.

The report, obtained by People Magazine, also indicated that Kohberger would stay “awake all night” while moving around the jail cell.

The inmate reportedly added that Kohberger seemed interested in why other inmates had been arrested, but never spoke about the University of Idaho murders.

The only incident in which the inmate witnessed Kohberger getting angry was when another inmate yelled, “you suck,” while he was on a call with his mother. Kohberger, visibly upset, approached the man and asked if he had been talking about him and his mother.

The report said that the pair talked things out, according to what the report said.

Kohberger, convicted for the November 2022 murders of University of Idaho students, Ethan Chapin, Xana Kernodle, Madison Mogen, and Kaylee Goncalves, transferred this month to the J Block at the Idaho Maximum Security Institution, which is around nine miles south of Boise.

He will reportedly stay confined in a single-person cell and allowed one hour per day for outside recreation. He’ll be transferred while wearing shackles and allowed a show every few days.

The Idaho Statesmen reports that IMSI is known for its harsh conditions, with a reputation for holding inmates in solitary confinement for nearly 24 hours a day.

Reports have also indicated that inmates have limited medical care, unclean water, unsanitary conditions, and a high turnover rate, leading to ongoing under-staffing. The prison also houses death row inmates and is equipped with armed guard towers, razor wiring and double perimeter fencing.

The Independent reports that in 2024, the Security Journal Americas listed IMSI as one of the nation’s worst prisons, with clogged vents, feces-covered walls, biohazard-level HVAC problems, and moldy showers.

The prison housed notorious spree killer Paul Ezra Rhoades, who died by lethal injection in 2011, for the deaths of three women. The prison also houses Chad Daybell, who was convicted of killing his two stepchildren and his former wife.
