Four people were killed in a shooting at a car wash in Pennsylvania on Sunday morning and the shooter is in critical condition, state police said. Officials originally reported five people were killed in the shooting, but police later identified the fifth person as the suspected shooter, 28-year-old Timothy Smith. Smith was hospitalized with a gunshot wound to the head and is not expected to survive. Officials said it is possible the gunshot wound was self-inflicted. A woman survived the shooting, but sustained minor injuries from broken glass, as officials believe she was able to duck out of the shooter’s view. Officials said the shooter was armed with an AR-15 semi-automatic rifle, a 9-millimeter handgun and a 308 rifle and was wearing body armor. Pennsylvania State Troopers said a motive for the shooting had not yet been identified.
