Norton, Vt. — A 54-year-old Piermont man died on Wednesday afternoon while snowmobiling with colleagues in the Northeast Kingdom near the Canadian border.

Andrew Boright was on a snowmobile trail with a group about a mile west of Route 114 in Norton when some of the snowmobiles got stuck, Vermont State Police said in a news release. After helping to extricate the sleds, Boright said he was not feeling well. The group continued its ride, but realized Boright had dropped back and no longer was riding with them, police said.

Police said Boright was found slumped over on his snowmobile by an off-duty Orleans County Sheriff’s deputy, and that the snowmobile was still on the trail and did not appear to have been in a crash. Other snowmobilers stopped to help, and agents from U.S. Customs and Border Protection also brought medical equipment to the scene, but Boright could not be revived.

Vermont State Police started an investigation, but said at the present time Boright’s death does not appear to have been caused by an accident or other suspicious circumstances. An autopsy is scheduled.
