_Philadelphia Inquirer_. Police said an investigation is active and ongoing with the Homicide Division, and that no weapon was recovered on the scene. The _Inquirer_ reports the shooting was

one of 16 to hit Philadelphia this weekend, leaving a total of 26 injured and four dead. “We’re putting out additional people,” Ross said when questioned on the spate of violence. “We’re

ramping up our controls across the city.”
