PORTLAND — Andrew Bean pleaded guilty Tuesday in U.S. District Court to possessing a firearm after being convicted of four felonies.

According to court records, on Nov. 21, 2015, a Maine game warden discovered Bean, 51, in possession of a 12-gauge shotgun near his home on Christian Ridge Road in Paris. He was prohibited from possessing firearms based on prior felony convictions for operating under the influence and operating after revocation in 2002 and in 2006.

Assistant U.S. Attorney Michael Conley sought the possession change, arguing that Bean posed a safety risk to the community and was a flight risk.

According to a written statement from U.S. Attorney Thomas E. Delahanty II, Bean faces up to 10 years in federal prison and a $250,000 fine.

He will be sentenced after the completion of a pre-sentence investigation report by the U.S. Probation Office.

Bean’s brother, Stephen, 55, of Norway, and David Foster, 39, of Paris pleaded not guilty to the same gun charges at their arraignments in U.S. District Court on April 7. They were released on conditions, including notification to the court of any change of address or phone, pending their trials.

Andrew Bean has been held in federal custody.

The three Oxford County hunters were indicted last month by a federal grand jury on charges of being felons with firearms.

The three were charged earlier in state court with fraudulently obtaining hunting licenses and being prohibited persons with firearms.

The state and federal charges stem from an incident on property adjacent to a Paris farm, where the brother of two of the men shot and killed 18-year-old Megan Ripley in an unrelated hunting incident in 2006.

The recent case was investigated by the Maine Warden Service and the Bureau of Alcohol, Tobacco, Firearms and Explosives.
