This weekend, Mark McCarty reportedly barricaded himself inside the bathroom of a sporting goods store and killed himself with a self-inflicted gunshot wound to the chest.
According to the Associated Press, McCarty entered Dick's Sporting Goods in Fairless Hills, Penn., after 7 p.m. on Saturday and asked to see a shotgun and ammunition.
McCarty then pulled out a handgun (unloaded) and ordered a store employee to open the shotgun's gun lock. At that point, McCarty took the shotgun with him into a store bathroom where he barricaded himself inside, reports CBS Philadelphia.
The Dick's Sporting Goods store and nearby businesses were evacuated during the four-hour-long standoff with police. No one else was hurt.
McCarty had also been involved in a standoff with Middletown, Penn., police officers in 2002, said Lt. Henry Ward.
