Chester police are investigating a shooting that left one man dead and another wounded Tuesday night.

Officers responding to a report of gunfire found a 20-year-old man who had suffered multiple gunshot wounds lying face down on the sidewalk on the 200 block of Patterson Street at 7:08 p.m., police said.

The victim, whose name has not been released, was taken to Crozer-Chester Medical Center, where he was pronounced dead at 7:27 p.m.

Investigators learned that about the same time, a 19-year-old man suffering gunshot wounds to the leg had been dropped off at the hospital and was admitted for treatment.

Police said they determined that both men had been wounded in the same shooting.

The relationship between the victims, if any, has not been disclosed.

Police said they recovered numerous .45-caliber shell casings at the crime scene and found a .45-caliber Taurus pistol nearby.
