An 18-month-old girl is dead after she was run over by a school bus that had just offloaded children in the Chapel Hill area.

Authorities identified the girl as Arra Preciado.

Trooper Jean Dark of the Texas Department of Public Safety says the accident happened about 3:30 p.m. Tuesday about 3 miles northwest of Tyler on Pearl Street near the intersection of Gallion Avenue in Smith County.

Trooper Dark said the child walked in front of the Chapel Hill school bus as it pulled away from the stop, first knocking her down then running over her body.

Dark said the bus driver, at first, was unaware that the child had been run over but stopped around the corner from the site.
