A teenage boy and a man in his 20s, both wounded by weekend gunfire, were hospitalized Sunday as Philadelphia police continued to investigate the pair of shootings, which occurred just minutes and blocks apart in Overbrook on Saturday night.

The 15-year-old was shot in the right side of his neck, lower back, and upper right leg shortly before 11 p.m. along the 6700 block of Leeds Street, police said.

Officers took him to Penn Presbyterian Medical Center, where he was listed in critical but stable condition.

There was no word on a motive for the crime. Police described the suspect only as a black man wearing a black hooded sweatshirt.

Shortly after 11:30 p.m., an officer investigating the shooting scene heard a gunshot, police said.

About five minutes later, a woman was seen helping a 24-year-old man with blood on his shirt walk down 67th Street toward Leeds. She called out to officers, and the man told them he had been shot, police said.

Officers took him to Penn Presbyterian Medical Center, where he was treated for a gunshot wound to his right biceps and the right side of his torso; he was listed as being in stable condition.

Investigators received information that the man and a friend were outside on the 6700 block of Lebanon Avenue – about two blocks north of Leeds – earlier in the evening and saw a silver crossover-type vehicle drive by, then stop. The driver called out a name to the victim, who replied the name was not his, police said. The vehicle then sped away.

The victim and his friend briefly entered a house along the block, police said. When they came back outside, they saw the same silver vehicle parked on the street. The man who had earlier called out to the victim got out of the vehicle and shot him once, police said.

That alleged shooter is described as a 5-foot-3 to 5-foot-5-inch black male with a short, full beard. He was last seen wearing a black skullcap, black pants, and a black hooded sweatshirt, police said.

It was not immediately clear whether the two shootings were related or whether the same gunman was involved in both.

Authorities asked that anyone with information contact Philadelphia police at 215-686-8477.
