Bryan Kohberger's attorneys want to force victims' roommates to testify | LiveNOW from FOX

A defense investigator working on behalf of University of Idaho student murders suspect Bryan Kohberger asserted in a newly unveiled court filing that a surviving housemate has "exculpatory" information that is "material and necessary" to the alleged killer's defense. Kohberger, a former criminology Ph.D. candidate, is accused of entering an off-campus home before fatally stabbing four of the six people inside, Madison Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin. The three women lived there with the two survivors. In the documents, obtained by Fox News Digital, the subpoena demands the roommate's appearance on June 28, two days into Kohberger's planned preliminary hearing, and warns of a potential fine of $500 or 25 days in jail if she refuses to appear.
