Police said Zhafir Tinsley-Jones is wanted in relation to the homicide of 79-year-old Robert Womack.
The incident began around 5 p.m. Wednesday when police were called for reports of shots fired in the area of 3rd Street and Highland Avenue.
While officers were on their way to the call, officials said they were informed of a car accident in the area of 3rd and Wilcox streets that might be related to the shots fired.
Natisha Moore, who lives in the area, said her car was one of several that were hit at the time of the crash.
"I was in the back of the house and I heard gunshots. I was literally about to come out of the house and leave when that happened," she said.
Police arrived at the accident scene and found Womack with a gunshot wound in the back of his head sitting in the driver's seat of a crashed car.
"There were kids in the park looking into the car so we were trying to get the kids away," Moore said.
Paramedics attempted to treat Womack, but he was pronounced dead at the scene.
Investigators said they believe Tinsley-Jones shot and killed the 79-year-old victim in his vehicle that eventually crashed.
"That's so sad like these kids shouldn't have guns. They should have something better to do than shooting people," Moore said.
Anyone with information or who knows the whereabouts of Zhafir Tinsley-Jones is asked to call 911 or contact Detective Joseph McFate at 610-447-8428 or email@example.com or Detective Vincent Ficchi at 610-891-4681.
