His car, parked outside Mercy Hospital, had bullet holes in the driver-side door and window. The man had been shot three times, once each to the left shoulder, left side of his chest, and left side of his stomach.
At 1:19 a.m., police said, they received reports of a man screaming "Being assaulted with a stick or bat!" on the 5900 block of Charles Street in Wissinoming. They found a 31-year-old man bleeding from his head due to head trauma, slumped over in the driver's seat of his car, a blue Hyundai Tiburon.
Medics pronounced the man dead on the scene at 1:36.
His name has not been released, pending notification of family.
In connection with that incident, police were searching for four men who, they said, were in a black car - possibly a black Ford Crown Victoria with tinted windows - that was last seen driving east on Charles Street toward Benner Street.
Saturday's second homicide occurred about 1:40 in North Philadelphia, police said.
A 39-year-old man was found with gunshot wounds to his head and stomach, police said, by a family member in the living room of a home on the 1300 block of West Lippincott Street.
Medics took the man to Temple University Hospital, just a few blocks away; he was pronounced dead at 2:03.
Police have not released his name. Investigators had not identified a shooter or motive.
Saturday morning's violence followed a series of incidents Friday night, including a shooting just before 10:30 on the 4400 block of North Holden Street in the West Powelton section of the city that left a 22-year-old man in critical condition.
Police had not made an arrest in that shooting.
