Bryan Kohberger’s legal team addressed how his diagnosis with autism may influence a jury as part of an attempt to get the death penalty taken off the table if he’s found guilty.

Legal filings also show that prosecutors want to introduce evidence of Kohberger’s “click history” at Amazon.com showing that he purchased a Ka-Bar brand fixed-blade knife eight months before the killings. A Ka-Bar knife sheath was found next to one of the victims.
