SIDNEY, Maine — A man is dead after a snowmobile crash in Sidney late Tuesday night, according to a news release issued by the Maine Warden Service.

Wardens said Jeffrey Fisher, 32, of Sidney was found dead along the shoreline of Messalonskee Lake after he became separated from his friend while on an overnight snowmobile ride.

Fisher crashed his snowmobile and was ejected onto rocks at the shoreline, according to the release. He was pronounced dead at the scene.

Wardens said Fisher was operating an Arctic Cat snowmobile and was wearing a helmet.

Speed is likely a contributing factor in the crash, based on an initial witness statement and evidence at the scene, according to Wardens.

An autopsy was to be performed at the state medical examiner’s office in Augusta.

The case is under investigation.

This is Maine’s fourth snowmobile-related fatality this season.
