A 29-year-old Palisade woman involved in a crash in western Colorado that killed a man on a cross-country bicycling trip has been charged with two counts of vehicular homicide -- one alleging DUI and the other alleging reckless driving.

The Grand Junction Daily Sentinel reports Tonie Rosales appeared in court Thursday for the Sept. 18 crash on U.S. Highway 50 that killed 25-year-old Eunjey Cho, who was riding from Seattle to Princeton, N.J.

Arrest records say Rosales told police she was running late for a court hearing in Delta related to a previous DUI arrest when she fell asleep at the wheel and hit Cho's bicycle. Prosecutors haven't said what substances she is accused of having in her system.

Cho was a volunteer with the Jesuit Volunteer Corps Northwest in Spokane, Wash.
