Cheyenne, WY – A civil trial in the 2001 carbon monoxide death of a man at a Vail Resorts lodge got underway in U-S District Tuesday. Fifty-one year old Doctor David Williams and Joette Williams were staying at the Snake River Lodge and Spa near Jackson when carbon monoxide allegedly seeped into their room. He was killed and she suffered injuries. In opening arguments, attorney Robert Shuster said Vail Resorts knew of the carbon monoxide problem, but did little to fix it before the death. Defense attorney Earl Gunn admits something went wrong. But he's focusing more on the extent of Joette Williams' brain injuries and the amount of lost income and medical expenses sought in both lawsuits. The trial is expected to last through December.
