GILLETTE, Wyo. (AP) — A judge has ordered a bus driver to stand trial on three felony counts of aggravated vehicular homicide in an accident that killed three Gillette men earlier this year.

Campbell County Circuit Judge Terrill R. Tharp on Friday ordered 53-year-old Rhoda J. Steel to stand trial.

Prosecutors say Steel drove a Coach USA bus full of coal miners into a line of vehicles stopped at a construction zone May 14 on Highway 59 south of Gillette.

The collision caused a chain-reaction crash that killed 37-year-old Colin Schultz; 55-year-old Charles Errington and 40-year-old Christopher Joubert.

Tharp ruled that prosecutors had presented sufficient evidence that Steel consciously disregarded risks and didn't follow a reasonable standard of care.
