ASPEN, Colo. — A 31-year-old man accused of
pushing a snowboarder off a chairlift at Aspen Highlands has pleaded not guilty by reason of insanity.
Thomas Proesel is accused of assault and reckless endangerment. He entered his plea Monday.
The Aspen Times previously reported that Proesel has spent several weeks in a Grand Junction mental health facility to receive treatment for an undisclosed, but serious, illness. Proesel is from Chicago but has been living in Aspen, the newspaper reported.
Prosel is accused of pushing Seth Beckton off the Loge Peak lift on Jan. 17. Beckton posted about the incident on his Facebook page. Beckton said he fell face-first 20 to 25 feet but landed in a “large pocket of snow” and was not injured.
Beckton said he was pushed after making a comment to the effect of: “To get (chest) deep pow shots you just need to be on your edges.”
“I honestly thought I was dead,” Beckton told the newspaper last month. “Because I didn’t know where we were (within the lift path). It’s not cool to think anyone would do that.”
Beckton, 28, said it happened about 9:30 a.m., but he did not report it until the end of the day. Aspen Skiing Co. and the Pitkin County Sheriff’s Office reviewed video to track down Prosel.
