An official walks along a line of tow trucks on Indian Creek Valley Road as they remove three vehicles from a scene where a shooter killed four people Sunday, Jan. 28, 2018, outside Ed's Carwash in Saltlick Township, Fayette County, Pa. A jealous ex-boyfriend opened fire and killed four people at a car wash early Sunday morning in Pennsylvania, while a woman hiding in the back of a pickup truck suffered only minor injuries, according to police and the wife of one of the victims. State police said Timothy Smith, 28, was armed with a semi-automatic rifle, a .308-caliber rifle and a handgun and was wearing a body armor carrier without the ballistic panels inserted when he opened fire early Sunday morning at Ed's Car Wash in Saltlick Township, a rural town about 55 miles (89 kilometers) southeast of Pittsburgh. “Trying to investigate why this happened and how it happened.”

An injured person was taken to a hospital, but it’s not clear if that person was shot, state police said. Family members of the victims told WPXI-TV the shooting was the result of a domestic dispute, and claim the shooter was a man who used to date one of the victims.
Four people are shot and killed at a car wash in the Melcroft suburb of Saltlick Township in Pennsylvania. A fifth person, believed to be the gunman, is severely injured.
