WEST MIFLIN, Pa. (AP) — A domestic dispute between a man and his mother ended when another man who was trying to calm the situation was shot and killed during a struggle over a gun. Authorities say 19-year-old Dante King faces a homicide charge in the death of 21-year-old Anthony Orosco. The shooting occurred late Saturday at the West Miflin home of King’s mother. Authorities say King got a gun during the dispute and, as he and Orosco fought to control the weapon, it went off and Orosco was shot once in the upper chest. Orosco was taken to a hospital but was pronounced dead there a short time later.
