Video of the incident shows two police officers backing away from the man, who was wielding a knife and coming toward the officers. His mother is seen futilely attempting to hold him back, before officers fire on him, killing him. At one point in the video, officers can be heard ordering Wallace to put down the knife.
Wallace’s mother said he was suffering from a mental health issue. His family has called for peace.
Despite Penn. Gov. Tom Wolf ordering the National Guard into Philadelphia Tuesday evening, riots and widespread looting have broken out.
