PUEBLO, Colo. -- A teenage girl is dead and three other people have been taken to hospitals after a one-vehicle crash east of Pueblo.

The Colorado State Patrol said a 16-year-old girl was driving a 2000 Oldsmobile van eastbound along Colorado 96 near Boone, Colo., when the van went off the right side of the road, struck a pole and hit a bridge embankment at about 6:20 p.m. Sunday. The van then came to rest in an irrigation ditch.

The girl was airlifted to St. Mary-Corwin Medical Center in Pueblo, where she died. Three other people, including a 3-year-old boy, were taken to hospitals with undisclosed injuries.

The boy was in a safety seat. The state patrol said it was unclear if the others were wearing seat belts.

No names have been released.

A teacher at Crowley County High School, in Ordway, told The Pueblo Chieftain that the girl who died was a student there, and that she had been traveling with her mother, nephew and a female friend from school.

Boone is 20 miles east of Pueblo and 110 miles southeast of Denver.
