It should have been a routine delivery with the 32-year-old FedEx driver dropping off a package to a home in the area, but that's when police say, an armed gunman approached and robbed the driver, perhaps not anticipating that the FedEx driver was also armed.

"He was able to tell police that he was making a delivery on the 600 block of Unruh and right when he got done making that delivery, he was approached by at least one male and he was robbed at point of gun," Philadelphia Police Chief Inspector Scott Small said.

Police say the driver was shot once in the abdomen during the robbery. Police say as they were receiving calls about shots fired in the area, the FedEx driver was able to drive himself to a nearby parking lot away from the scene.

He was transported to Einstein Medical Center and is in stable condition.

He told police that after being shot in the stomach, he pulled out his own weapon and returned fire at the suspect.

"Initially, we did not know whether the perpetrator was struck by gunfire," Small said.

But minutes later, police were called to the 1400 block of Creston Street where they found a 27-year-old man in a driveway suffering from multiple gunshot wounds to the chest, back and torso. The suspect died at the hospital.
