Sandy police say a 2-year-old boy visiting from Colorado for a summer vacation accidentally shot himself in the head with a gun in his grandparents' home.

Police Sgt. Jon Arnold says the boy was airlifted to Primary Children's Medical Center after emergency crews were called about 7 p.m. Tuesday, but he died at the hospital.

It was not immediately clear how the boy got hold of his grandfather's 9 mm handgun. Arnold says the boy was alone in a bedroom at the time of the shooting, but that other family members were elsewhere in the house.

The name of the child has not been released. His family lives in the Denver area.
