The man accused of pushing a snowboarder off of an Aspen lift was found legally insane by a state psychiatrist, according to the Aspen Times .
Thomas Proesel allegedly pushed Seth Beckton off of a chairlift in January at Aspen Highlands, causing Beckton to fall about 25 feet. Becton was uninjured.
Proesel has been charged with felony attempted assault.
In April, Proesel entered a plea of not guilty over Skype from a psychiatric facility in Tennessee.
Proesel's arrest warrant says he made nonsensical statements to police, which possibly included something about a terrorist.
Pitkin County Judge Chris Seldin set July 15 as the bench trial date for Proesel in the interest of granting the suspect a speedy trial.a
