The video obtained by "Dateline" is among the evidence that investigators believe trace his movements around the time four University of Idaho students were killed.

Kohberger’s attorneys have already informed the judge that they believe someone else is responsible for the pre-dawn stabbings at a student house in Moscow, Idaho — the “alternative perpetrator” theory, Judge Steven Hippler revealed. Now the judge is telling lawyers to name the suspect and offer up “any actual evidence” they have against him.

More details about the murders of University of Idaho students Ethan Chapin, Xana Kernodle, Kaylee Goncalves and Madison Mogen and suspect Bryan Kohberger were revealed on Dateline.
