Four people were killed and two others injured after a gunman opened fire at a car wash in Pennsylvania, United States, on Sunday. The shooter, 27-year-old Timothy O'Brien Smith, may have resorted to this violent act either because of a domestic dispute or due to some personal animosity, said reports.
Reports say that one of the victims, Chelsie Cline, was known to Smith and that the latter had developed an obsession over her.
Smith sustained a possibly self-inflicted gunshot wound to the head and was transported to a local hospital, where he was on life support, said a Huffington Post report.
Shots were fired around 3 a.m. (local time) at Ed's Car Wash in Melcroft, about 55 miles (around 75 kms) southeast of Pittsburgh, Pennsylvania. Smith was reportedly armed with an AR-15 semi-automatic rifle, .308-caliber rifle and a 9mm handgun.
Police identified the victims as: William Porterfield, 27, Chelsie Cline, 25, Seth Cline, 21, and Courtney Snyder, 23, said a USA Today report.
Although there is no confirmation, some reports suggest that the shooter, Timothy O'Brien Smith, used to date one of the victims, Chelsie Cline.
All in all, "obsession" and "unrequited love" may have led Smith to carry out this senseless act.
