BRIDGEVILLE, Pa. -- An armed man strolled to the back of an exercise class at a health club in suburban Pittsburgh on Tuesday night and then pulled out two guns and started spraying bullets, leaving four people dead, including himself, and injuring at least 10 others, police and a hospital said.
"He did not say anything," Allegheny County police Superintendent Charles Moffatt said. "He walked right into the room where the shootings occurred as if he knew exactly where he was going."
Area hospitals were treating the other victims, including two in fair condition.
The shooting was at the L.A. Fitness Center in Bridgeville, a community of about 5,000 residents not far from downtown Pittsburgh and the Pittsburgh International Airport.
Debi Wozniak, of Dormont, a suburb of Pittsburgh, is a regular at the weekly Latin impact dance exercise class. She was running late Tuesday night and didn't make it, but she said her sister, Joann Gazzam, was in the class.
Gazzam told Wozniak that a man came in through the glass double doors at the exercise room's entrance. He walked to the back of the room near some weights and set down a bag, fumbled with it for a few minutes and came up with what Gazzam said were apparently two guns and began shooting.
Gazzam told Wozniak that several people appeared to be wounded, including the instructor, and that it was apparent that four people were dead and that the gunman had killed himself.
"She told me, 'Debi, I seen everything. Oh, my God, I seen everything. I seen him pull out the guns,"' Wozniak said.
Moffatt said police recovered two guns from the scene. He would not discuss a possible motive for the shooting, whose victims hadn't been identified.
"As you can imagine in a fitness club, they don't have identification on them," he said.
UPMC Mercy Hospital said five critically injured women were taken there. Allegheny General Hospital said it had two women in fair condition with gunshot wounds.
St. Clair Hospital said one of the victims of the shooting died there. Spokesman Rich Sieber said the woman was shot in the chest. He said two other victims were taken to his hospital, both in stable condition.
The fitness center, which opened last year, is in a strip mall called the Great Southern Shopping Center, where a few businesses were destroyed in a 2006 fire. It said in a statement: "Each of us in the LA Fitness family are shocked and saddened by the senseless acts of violence that took place."
