Walter Wallace Jr.’s family has reviewed body camera footage of his fatal shooting by

The emergency calls and body camera footage will be released to the public in the next couple of days, Philadelphia Police Commissioner Danielle Outlaw said Wednesday. She will also release a history detailing previous police responses to the home, she said.

Wallace, 27, was shot and killed Monday while holding a knife during a confrontation with police in West Philadelphia. His family has said he suffered from bipolar disorder and was in crisis at the time of the shooting. A family attorney said Wallace was a mental health patient who was prescribed lithium.

The police shooting has set off unrest in the city the past few nights, with demonstrators marching in the streets and some incidents of looting, property destruction and attacks on police officers. A citywide curfew of 9 p.m. to 6 a.m. began Wednesday night and will be reevaluated daily, Mayor Jim Kenney said.

Pennsylvania National Guard members will guard businesses to prevent looting, but troops will not be deployed until later this week, officials said.

People hold banners and signs during a demonstration in Philadelphia on October 27, 2020, over the police shooting of 27-year-old Walter Wallace Jr.

In the past three nights, there have been 212 arrests, and 57 officers have been injured, including one who remains hospitalized, officials said.

On Thurday, US Attorney of the Eastern District of Pennsylvania William M. McSwain announced federal charges against four people who allegedly destroyed police vehicles during unrest on May 30. McSwain warned that any violence this week would similarly be punished.

What led to the shooting

Authorities are investigating what the two responding officers, who didn’t have Tasers, knew when they answered a call about a man with a knife.

Police said the incident started with a call about a man with a knife, KYW reported. Officers who responded saw a man brandishing a knife and waving it erratically, Philadelphia Police Sgt. Eric Gripp told KYW.

Shaka Johnson, an attorney for Wallace’s family, said relatives had made at least three calls to authorities that day. The initial call was for an ambulance, he said, but police arrived first.

What we know about the Philadelphia Police shooting of Walter Wallace Jr.

It’s unclear how many calls police responded to on Monday. CNN reached out to police and the family attorney for clarity.

At a Tuesday news conference, police officials did not answer questions about whether officers were there earlier in the day or had previously interacted with Wallace. They did not say what officers knew of the situation prior to arrival.

When police arrived at the man’s house, JaHiem Simpson, who took video of the police shooting, told CNN a person who he later was told was Wallace’s mother told police that Wallace had mental health issues.

Simpson said Wallace exited the house with a knife and everybody told him to put the knife down. Simpson said he saw officers pull their guns as soon as they saw the knife.

The two officers can be seen in the video backing up as he walks towards them. Multiple shots ring out as police fire, striking him. Sgt. Gripp told KYW that an officer took Wallace in his police cruiser to Presbyterian Hospital, where he died.

Officers did not have tasers

Former Philadelphia Police Commissioner Charles Ramsey told CNN’s “New Day” the case is not as clear-cut as some other police shootings because Wallace was armed.
