9-year-old girl killed by falling school gate in Arizona; sheriff says "no criminal violations"

A sheriff's investigation into last week's death of a 9-year-old girl at a Tucson elementary school found no evidence of any criminal violations.

The girl, whose name has not been released, died Nov. 17 after she was struck by a heavy metal gate at Centennial Elementary School.

School district officials said she was helping close the gate at the end of the school day when it disconnected from its support and fell on her.
