PHILADELPHIA (WPVI) — A man has died after he was found shot inside a corner store in the Summerdale section of Philadelphia.

It happened just before 9 p.m. Monday along the 800 block of Marcella Street.

Police said the 18-year-old victim was found unresponsive inside the store, suffering from at least one gunshot wound to the head. He was transported to a nearby hospital, where he was pronounced dead.

Investigators said approximately 26 shots were fired during the incident.

“At least one casing is inside the store where we found the victim, and multiple shell casings are on the sidewalk and on the highway,” Chief Inspector Scott Small said.

Authorities said two occupied homes were also struck by gunfire, though no injuries were reported inside either residence.

“Bullets went through the properties, and they went through the second-floor front bedroom windows of both of these properties,” Small said.

Police also discovered a stolen vehicle that had crashed into an unoccupied parked car near the shooting scene.

“The engine is still running. The driver’s side front and rear doors were open as if somebody fled from that vehicle,” Small said.

Police have not identified the victim. The employee of the corner store said the man frequented the business to play games of skill.

Investigators have not determined what led to the shooting.

No arrests have been made.

Anyone with information is asked to call police at 215-686-TIPS.
