FOX CHAPEL, Pa. (AP) — A 5-year-old girl has been killed in an all-terrain vehicle crash that also left her father and older sister hospitalized. Allegheny County police say the accident in Fox Chapel occurred Thursday night. The 57-year-old father was driving the ATV in the family’s front yard with his children as passengers when one of the girls reached up and hit the throttle. The ATV sped forward, crashed over a hillside and struck a tree. The 5-year-old was taken to a hospital but died there a short time later.
