State police say 12-old-twins were playing with guns at their central Pennsylvania house while their parents were away when one of guns went off, critically injuring one of the boys.
The shooting occurred just before 6 p.m. Saturday in East Hanover Township.
State police say the twins were apparently playing with a .45-caliber semiautomatic pistol and a 357 magnum revolver when the pistol went off and hit one of the boys. The uninjured twin called 911.
Emergency responders transported the injured boy to Hershey Medical Center, where he is listed in critical condition.
State police were able to contact with the boys' parents and they came home. No further details were immediately released.
The shooting remains under investigation.
