Adrian Williams, 29, was fatally shot by a Pittsburgh police officer after a police pursuit in the early hours of April 21, 2014. The chase began about 3:20 a.m. when officers tried to stop Williams for a traffic violation in the Larimer neighborhood; it continued into Wilkinsburg and ended when his vehicle crashed on Trenton Avenue. Williams exited the car and, according to police, ran into backyards while armed. Officers repeatedly ordered him to drop the handgun but say he did not comply.

Officer Christopher Kertis, who had arrested Williams in 2012, fired multiple times and struck Williams six times; Williams died at the scene. The Allegheny County District Attorney reviewed the shooting and in June 2014 announced it was justified, saying video showed Williams pointing a gun at Kertis before he fired. The DA’s office later forwarded the file to the U.S. Attorney’s Office for federal review. Does anyone have additional information or eyewitness detail about the chase or the moments after the crash?
