Police shot and killed a man on a West Philadelphia street Monday afternoon after yelling at him to drop his knife. It happened around 3:50 p.m. when officers responded to a domestic call along the 6100 block of Locust Street. Sgt. Eric Gripp says officers confronted a man with a knife at the scene. Gripps say the man was shot multiple times by two officers after he didn’t adhere to calls to drop the weapon. He was later pronounced dead. Neighbors have identified the man as Walter Wallace. Video of the fatal confrontation recorded by a bystander and posted on social media shows officers pointing their guns at a man as he walked in the street and around a car. The man walks toward the officers as they backed away from him in the street, guns still aimed at him.
