GREENVILLE, Maine (WGAN)  Maine game wardens say they are investigating the death of a Greenville man found dead in Moosehead Lake Wednesday morning.

Wardens say the body of 46-year-old Matthew Dubien was found in open water near Hartford’s Point.  Warden’s say Dubien had been missing since 11 p.m. Tuesday night after leaving a local restaurant on his snowmobile.

Wardens say this morning, Dubien’s family contacted them when they realized he had not made it home.  Around 9 a.m., wardens were searching the west short of Moosehead Lake when they found Dubien’s snowmobile helmet.  They found his body in nearby open water a short time later using an airboat.

The warden service says they are investigating to determine contributing factors that may have caused his death.

Wardens are reminding Mainers that many lakes, including Moosehead Lake, now have several open areas of water that, just a few weeks ago, were covered in ice.  They say anyone accessing Maine’s waterways should try to be certain of the ice conditions, especially at night.

This is the sixth snowmobiling related fatality in Maine this season.
