ROCK SPRINGS, Wyo. (AP) — A Montana man pleaded not guilty in a Wyoming court to the alleged aggravated vehicular homicide of his daughter.

Brian Harley Fletcher of Sand Springs, Montana, also pleaded not guilty to alleged failure to maintain a single lane of travel and two counts of failure to secure a child in a child restraint in Sweetwater County 3rd District Court in Green River, Wyoming.

A cash or surety bond of $100,000 was continued.

Fletcher has filed a demand for a speedy trial. The trial is set for May 7.

A Wyoming Highway Patrol affidavit says Fletcher's 8-year-old daughter died in a single-vehicle crash east of Rock Springs in 2016. Fletcher was the driver.

A chemical test of Fletcher's blood allegedly showed the presence of methamphetamine, amphetamine and alprazolam (Xanax).
