POLAND, Maine (AP) — The Maine Warden Service says it's investigating a fatal snowmobile crash that killed a 17-year-old Massachusetts resident.

The Warden service says the crash occurred on Thompson Lake in Portland just before 11 p.m. on Saturday and killed Troy Marden of Amesbury, Massachusetts. The service says two snowmobiles were operating on a plowed portion of the lake when the snowmobile operated by Marden failed to negotiate a corner and hit a snowbank.

Wardens say the operator of the other snowmobile tried to assist Marden before getting help. Marden was pronounced dead at the scene.

The warden service is also still investigating another snowmobile crash that resulted in a death on a Norway lake Saturday. The service says that crash killed 52-year-old Gracie Herrick Onofrio of Norway.
