DILLON, Mont. (AP) — A 49-year-old Dewey man is charged with vehicular homicide while under the influence of methamphetamine in the hit-and-run death of a woman who was walking along Interstate 15 near Dillon.

Donald G. Welborn is charged with striking 32-year-old Mary Elizabeth Merino of Divide at about 2:10 a.m. on Oct. 28. Beaverhead County Justice of the Peace Candy Hoerning said Welborn made an initial appearance in her court on Friday. His arraignment in District Court has not been set and he asked for a public defender. Welborn remains jailed with his bail set at $100,000.

Sheriff Franklin Kluesner told The Montana Standard (http://bit.ly/1P5U3Nr ) that it appeared Merino had left a disabled vehicle and was walking along the interstate when she was hit.

Welborn was arrested less than an hour later.
