The suspected gunmen were among those injured in a pair of shootings Thursday night that appear to be part of a rolling gun battle that moved through various Pittsburgh neighborhoods, police said Friday.
Among the others injured were a 7-month-old boy who was struck by broken glass when a car window shattered and a 22-year-old man police described as an "innocent bystander."
Lt. Daniel Herrmann said investigators believe two people were shooting at each other from cars in a moving gunfight that led to collateral injuries.
"These guys are exchanging gunfire between themselves and between cars, and stray shots were going elsewhere," Lt. Herrmann said.
Police have not released the names of the suspected shooters, one of whom was in critical condition Friday, and charges had not been filed.
The first shooting happened about 9 p.m. Thursday outside a Uni-Mart convenience store in the 700 block of Brownsville Road in Knoxville. A 7-month-old boy from Bon Air suffered minor injuries from broken glass when a window in the car in which he was sitting shattered, police said. Also in the car were the 27-year-old mother and a 47-year-old woman from Dormont; both were uninjured.
Six minutes later three people were shot in the 200 block of Michigan Street in Beltzhoover. Two were the suspects, police said. The other was a 22-year-old man who was walking home from a nearby bus stop.
Public safety spokeswoman Sonya Toler said one of the suspects is a 20-year-old man from Allentown who was shot in the neck and was in critical condition at UPMC Mercy Friday morning. Another, a 21-year-old man from Penn Hills, was in stable condition after he was shot in the leg.
The man whom police have described as an "innocent bystander" was shot in the lower back and was being treated at Allegheny General Hospital, Ms. Toler said.
The baby was treated by medics at the scene.
"The parents had the medics look at him, and they took him home," Lt. Herrmann said.
Although no one is dead, the homicide squad is investigating.
