Teton Village, WY – A teenager faces a charge of negligent homicide for colliding with a skier while snowboarding at Jackson Hole Mountain Resort a year ago. Prosecutors say Greg Doda, of Crownsville, Maryland, ran into Heather Donahue in the Laramie Bowl last February. Doda was 16 at the time. He allegedly was going more than 35 miles an hour when he ran into Donahue, a 29-year-old from Massachusetts. A Sheriff's investigator says the impact knocked Donahue 25 feet down the hill. She died of a head injury.
