PHILADELPHIA (CBS) — Police have identified the suspect who died after a police-involved shooting in South Philadelphia.

Khalil Lawal, 31, is accused of hitting a pedestrian with his car at Broad and Bigler Streets around 7:30 a.m. on Monday.

Police say Lawal, of Arlington, Virginia, was driving a 2016 Dodge pickup West on Bigler, approaching Broad when an off-duty detective confronted the suspect after he reportedly witnessed Lawal chasing a concerned citizen that blocked him with an SUV.

Philadelphia Police Commissioner Richard Ross says the suspect attacked the detective and gave him head injuries.

“During the struggle, several shots were fired. The male was hit several times and later pronounced dead at Presbyterian Hospital,” said Ross.

Ross added, “I do have some concerns about the shooting. In particular, whether all the shots were necessary.”

Police would only identify the suspect as a 31-year-old man from Maryland. He was transported to Penn Presbyterian Medical Center where he was pronounced deceased at 10:15 a.m.

The man struck by the car received treatment for abrasions and contusions to his head and legs at University of Pennsylvania. He has since been released.

The officer was treated and released at Methodist Hospital for abrasions and contusions to his head and shoulder.

The officer has been placed on administrative duty as the investigation continues.
