An Old Fort man was found dead after a snowmobile accident in Maine on Wednesday morning.

According to a press release from the Maine Department of Inland Fisheries and Wildlife (MDIFW), local authorities located the body of 55-year-old Willard L. Hartsock of Old Fort after a snowmobile related incident in Rockwood.

Hartsock, it was reported, had been staying in a rental property on Lake Street in Rockwood and was seen around the area operating a new Ski-Doo 900 Expedition ACE snowmobile on Tuesday.

When Hartsock did not return to the property that evening, his family notified police and a search began around 9 p.m. During the search, authorities located Hartsock’s vehicle, a snowmobile trailer and various belongings, but not the snowmobile itself.

Game wardens and police located Hartsock’s body at 1 a.m. Wednesday morning along a portion of Interconnecting Trail System (ITS) 88 in Taunton & Raynham Academy Grant.

According to MDIFW, it’s believed that while Hartsock was operating the snowmobile, he approached a wet area on the trail, stopped and attempted to put the machine in reverse. While in reverse, the snowmobile, which weighed nearly 700 pounds, rolled over top of him.

The case is still under investigation by Maine authorities.
