Kohberger, 30, was moved to the Idaho Maximum Security Institution, south of Boise, just hours after being sentenced to four consecutive life sentences in July. He pleaded guilty to the first-degree murders of Madison Mogen and Kaylee Goncalves, both 21, and Xana Kernodle and Ethan Chapin, both 20.

The footage began circulating on social media Thursday and appears to depict Kohberger in prison clothing walking back and forth in a cell.
