Pitkin County sheriff's investigators have interviewed a skier who may have pushed a snowboarder off a chairlift at Aspen Highlands.

Deputy Alex Burchetta tells The Aspen Times the snowboarder and witnesses also were interviewed Wednesday, but no charges have been filed.

Seth Beckton says he was riding a lift with a skier and another man Sunday morning when he made an innocuous comment that apparently offended the skier. Beckton says the skier then pushed him off the lift, causing him to fall 20 to 25 feet.

Beckton says he landed in a pile of powder and was uninjured.

Authorities say they identified a possible suspect based on surveillance video at the bottom of the mountain. The resort has given information from scanners at two chairlifts to the sheriff's department.
