Recap: Police fatally shoot man, prompting hours of protests in West Philly

Police officers fatally shot a 27-year-old Black man armed with a knife during a confrontation Monday afternoon in West Philadelphia, an incident that quickly raised tensions in the neighborhood and sparked a standoff that lasted deep into the night.

Late Monday into early Tuesday, police struggled to respond to vandalism and looting along the commercial corridor of 52nd Street, an area that was the scene of clashes between police and protestors earlier this summer. At least one police vehicle was set on fire Monday night and destroyed, and several police officers were injured by bricks or other objects hurled from the crowd. One officer was hospitalized after getting run over by a speeding truck.

The protests came roughly four months after the death of George Floyd at the hands of Minneapolis police sparked widespread demonstrations in Philadelphia and across the country and a national reckoning over racial injustice and police killings of Black people.

Police fatally shoot a man in West Philly

Police officers fatally shot a 27-year-old Black man armed with a knife during a confrontation Monday afternoon in West Philadelphia that quickly raised tensions in the neighborhood.

Shortly before 4 p.m., two officers fired their guns at the man in the 6100 block of Locust Street. Police then transported him to Penn Presbyterian Medical Center, where he died shortly after.

Family members identified him as Walter Wallace Jr.

Wallace was an undetermined distance from the officers but a video from a bystander showed he appeared to be multiple feet from them when they fired numerous shots. The video depicts Wallace walking toward the officers and police backing away. The video then swings briefly out of view, and in that moment police fire at Wallace.

Police spokesperson Sgt. Eric Gripp said officers were called to the block and encountered a man who was holding a knife. Gripp said the officers ordered him to drop the weapon, and he “advanced towards the officers.” Gripp said investigators are reviewing footage of what happened. Both officers were wearing body cameras.
