LARIMER COUNTY, Colo. — A woman who was involved in a fatal hit-and-run crash was sentenced to 12 years in prison Tuesday following an earlier guilty plea to vehicular homicide and DUI, among other charges for the June crash.

Kassy Winburn, 34, was arrested after the Larimer County Sheriff's Office said she drove her car into the back of 38-year-old motorcyclist and Greeley resident Joseph Kroiss. The two were traveling on Interstate 2 near East Harmony Road.

Kroiss was a father of four girls, ages 16, 15, 13 and 9. He moved to Colorado four years ago from Minnesota
