A 21-year-old man was shot and killed execution-style inside a North Philadelphia store Monday, police said.

Officers responded for multiple calls of a shooting on Susquehanna Street near 19th around 4:50 p.m. They found the victim laying inside the store with multiple gunshot wounds to the head, face, chest and abdomen. The victim, whose name was not released, was rushed to Temple University Hospital and declared dead in 30 minutes.

Ballistic evidence indicates at least 14 shots from a semi-automatic handgun were fired, mainly at close range, said Police Chief Inspector Scott Small, noting that the victim was likely targeted. Investigators also viewed surveillance footage from inside the store, which had about 10 customers and employees at the time, Small said.

"The shooter walks in, pulls a gun, shoots the victim who is inside the store talking on a cell phone," Small said. "The victim runs down one of the aisles, the shooter follows him. As the victim lays on the floor, our shooter stands over him and continues firing shots."

The shooter, who was wearing a dark hooded sweatshirt covering part of his face, fled on foot.

No other injuries were reported.
