The first of six trials of Baltimore police officers charged in the death of Freddie Gray begins on Monday.
The trial for William Porter, who is charged with manslaughter and misconduct, could serve as a bellwether for the other officers’ cases. Porter has pleaded not guilty, according to NBC News.
Porter was involved in Gray’s arrest after he was transported to a police station in a police van. Prosecutors say Gray asked Porter for a medic, but one was never called.
Gray, 25, died of apparent spinal injuries a week after an arrest by Baltimore police officers. His death sparked outcry against police brutality, and was a motivating factor for the Baltimore riots.
