Bryan Kohberger appeared in an Idaho courtroom on Wednesday to enter a guilty plea in the murders of four college students. The 30-year-old former criminology student did so after taking a last second deal that allowed him to avoid the death penalty in exchange for pleading guilty to the murders of Kaylee Goncalves, 21; Madison Mogen, 21; Xana Kernodle, 20; and Ethan Chapin, 20.
