Around 8:00 p.m. Wednesday, 16-year-old Yasin Harvey went to the Koury Grocer corner store at 62nd and Callowhill streets with a group of friends.
An aunt of one of the boys had asked them to pick up something for her at the store.
Investigators say the 16-year-old victim had just stepped out of the store and joined three other friends on a corner.
Police say that's when a car pulled up, a window rolled down seven shots were fired.
"Windows came down and someone from inside the vehicle fired several times striking and killing the descendent," Philadelphia Police Captain James Clark said.
Yasin was the only one in the group hit. He was shot twice in the head, in the chest and in the arm.
He died in the hospital around 5:00 a.m. Thursday.
"We don't think he was the intended target, we just think wrong place at the wrong time," Clark said.
Investigators say the reason they believe this to be a case of mistaken identity is that the teen is not from the area where the shooting happened and has no connection to that area.
Family friend Lisa Tyler spoke about the 16-year-old to Action News Thursday night.
"He is a very good boy, he goes to school, honor roll student, never gets in trouble," Tyler said.
Police are now looking for a dark green Pontiac.
They believe it might be the same car involved in another shooting around the corner yesterday.
The corner store has multiple surveillance cameras and police are hoping it helps identify the car and the gunman.
Neighbors say drug violence has plagued the area.
"The thing that scares me more than anything is what's going happen as it gets warmer and hotter, things just seem to get crazier," West Philadelphia resident James Hackett said.
Anyone with information is asked to call police.
