Officers patrolling the area say they heard gunshots and found a 33-year-old man on the ground with gunshot wounds. That victim was rushed to the hospital where he was later pronounced dead.

“This 33-year-old victim shot two times in his chest. Now, based on ballistic evidence we know at least two shots were fired from a semiautomatic weapon,” Philadelphia Police Chief Insp. Scott Small said.

Police say the victim lived about a block away from the shooting scene. Investigators don’t have a motive and say the gunman remains at large.
