A Maine man has pleaded guilty in a U.S. District Court Tuesday to being a felon in possession of a firearm in which he faces prison time and a hefty fine.

According to court records, 53-year old Timothy Levesque of Trenton, Maine, pleaded guilty in U.S. District Court Tuesday for possession of four firearms within feet of where he was sitting when the U.S. Coast Guard boarded his boat off the coast of Lamoine while conducting a routine maritime safety and law enforcement patrol.

The boar was registered in Levesque name and he was the only person on the vessel at the time law enforcement boarded it.

Levesque knew that the firearms were on the boat and knew he had been prohibited from possessing firearms as the result of prior felony drug possession convictions.

If convicted, Levesque faces a fine of up to $250,000 and 10 years in prison.

The case was investigated, in part, by the U.S. Coast Guard Investigative Service, the BATFE, and the Maine Marine Patrol.
