BOISE, Idaho – Bryan Kohberger will spend the rest of his life in prison, but the details about how and where he’ll be kept are still emerging.

The 30-year-old former criminologist received four consecutive life sentences plus another 10 years for the murders of University of Idaho students Madison Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20, and Ethan Chapin, 20.

A source with knowledge of the case told Fox News Digital Kohberger was already in custody at the state prison in Kuna, about 16 miles from the Ada County courthouse, by Wednesday afternoon.

Kohberger’s sentence amounts to “life and death in prison,” as Latah County Prosecutor Bill Thompson put it during a rare news briefing after the hearing.

The Idaho Department of Correction declined to give specific details about the transfer process.

“Once in IDOC custody, the person goes through a Reception and Diagnostic Unit (RDU) process to evaluate their needs and determine appropriate housing placement; this process takes 7-14 days,” a spokesperson told Fox News Digital. “We wait until a person completes RDU to determine their classification, housing placement, and privileges.”
