New details in the case of convicted Idaho murderer Bryan Kohberger have been unsealed, revealing that the killer chased one of the victims.

In the days after murdering four University of Idaho students in an off-campus home, Bryan Kohberger’s behavior shifted dramatically and investigators would later find that he had fixated on news coverage of the killings and began paying for items in cash – often wearing gloves – as he avoided the area of the murders.

The facility is about 20 minutes outside Boise, where Kohberger appeared in court Wednesday to be sentenced to four consecutive life sentences plus 10 years for the fatal stabbings of Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin.
