==The Shooting==
The shooting occurred at a women's aerobics class at the LA Fitness center at approximately 8:15 p.m. The shooter entered the class, placed a duffel bag on the ground, turned off the lights, took out two handguns and began firing, police said. According to police, the gunman fired 52 shots with two Glock 9×19mm semiautomatic pistols before committing suicide by shooting himself in the head with a .45-caliber revolver. A .32-caliber semiautomatic pistol found in his pocket was not used.

Three women and the gunman died, and about nine other people were injured. The Allegheny County Medical Examiner's office identified the three women who died as Heidi Overmier, 46, of Collier Township; Elizabeth Gannon, 49, of Green Tree, Pennsylvania; and Jody Billingsley, 38, of Mt.
