The only reason police responded to the West Philadelphia block was because of concerned neighbors.

Chief Inspector Scott Small says, “Witnesses along the block saw the vehicle with the engine running. They saw the male sitting in the driver’s seat. He appeared to be sleeping, or they thought he was sick.“

19th District police arrived around 2 a.m.

Officers found the car idling on the 1600 block of North Redfield Street.

The driver’s side window was down and the man behind the wheel was slumped in his seat.

Only after officers lifted the man’s shirt did they see he was shot at least three times.

Small says, “There was some ballistic evidence inside the vehicle, so it appears the victim was sitting in the driver’s seat when he was shot and killed. “

The medical call turned into a homicide investigation.

After spending hours at the scene, Philadelphia Police towed the car. Police say the victim was known to borrow it from a friend.

Now detectives will be back on scene today.

“Homicide is knocking on doors on this mainly residential block to see if anyone saw or heard anything. “

At this time, there are no suspects or a motive.

The victim is only identified as a 25-year-old man who lives on the block.

His family and witnesses are now in the process of being interviewed by police.
