MOUNT OLIVER, Pa. (KDKA/AP) – Authorities in western Pennsylvania say two boys are expected to survive critical injuries in a drive-by shooting near Pittsburgh that also wounded two other people.

Police chief Matt Juzwick told the Pittsburgh Post-Gazette on Saturday that a 13-year-old boy hit by the 7 p.m. gunfire in Mount Oliver improved after surgery at UPMC Mercy.

He said an 11-year-old boy taken to Children’s Hospital of Pittsburgh had also improved.

A 16-year-old was also taken to UPMC Mercy with minor injuries and a man was treated at the scene.

Gunfire erupted Friday night on Brownsville Road in Mount Oliver, near the city line.

Police said the three teenagers were shot on steps near a convenience store and the adult was hit on the opposite side of the street.

The man said the driver and front-seat passenger fired out of both sides of a dark-colored car. Juzwick said the motive for the shooting is unknown.

A woman who was by a Rite-Aid Pharmacy near the shooting scene said she was standing outside the drug store, and all of a sudden shots went off.

“Concrete from the drug store hit my shirt, and a bullet went through the glass [in the pharmacy door] just above my head,” she said.

The woman, who did not want her name used, said, “if I was a couple of inches taller, I would have been hit.”

“It’s terrifying because you don’t want to walk the streets anymore here, for fear of being shot,” said neighbor Phyllis Workinger.
