A Caribou man was killed Friday night in a snowmobile crash. Emmanuel Bouchard, 25, was riding a 2021 Polaris snowmobile in a group of 12 other people about 9:30 p.m. in Stockholm. When the group arrived in Caribou, they discovered Bouchard wasn’t with them, according to Mark Latti, spokesperson for the Maine Department of Inland Fisheries and Wildlife. Four snowmobilers headed back out on the trail to find Bouchard.
