Philadelphia District Attorney Larry Krasner held a news conference to give an update after five people died in a recent mass shooting.
The person accused of killing five people in the Kingsessing neighbourhood of Philadelphia on Monday was charged with five counts of murder, among other charges, during a preliminary arraignment on Wednesday.
Mr Krasner had already identified on Tuesday the 40-year-old accused shooter as Kimbrady Carriker, who is now facing charges of murder, aggravated assault and weapons offences.
The suspected assailant, dressed in a bullet-proof vest and ski mask and armed with an AR-15-style rifle and a handgun, fired a rifle “seemingly at random” around 8.30pm on Monday.
Five people were killed in the attack: Lashyd Merritt, 22; Dymir Stanton, 29; Ralph Moralis, 59; Joseph Wamah Jr, 31, and Daujan Brown, 15.
