All the victims are women:
At least two people were killed and several others wounded tonight when a gunman walked into a fitness center in the Great Southern Shopping Center in Collier and opened fire.
An Allegheny County policeman said he believes one of the dead was the gunman. Witnesses said they saw two to four wounded women lying outside the back door and two others lying in a parking lot at the side of the LA Fitness center along Washington Pike.
Witnesses said a gunman wearing a black hat walked into an aerobics room filled with women shortly after 8 p.m., turned out the lights and opened fire.
Witnesses reported hearing dozens of gunshots before the shooting stopped.
Police and paramedics from a number of South Hills communities rushed to the scene.
