Mass murderer Bryan Kohberger's sister has broken her silence after her brother was found guilty of killing four University of Idaho students. Ethan Chapin, 20, Xana Kernodle, 20, Madison Mogen, 21, and Kaylee Goncalves, 21, were found dead in their shared Moscow home on November 13, 2022. Weeks later, Kohberger was arrested in connection with their deaths at his parent's property in Pennsylvania. Following a lengthy investigation, Bryan, 31, confessed to the grisly murders last July and was sentenced to serve life in prison without the possibility of parole.
