BANGOR, Maine — A Caribou man pleaded guilty Thursday to a charge of unlawful possession of a firearm by a felon, U.S. Attorney Thomas E. Delahanty II said in a news release.

George D. LaCasse, 35, faces up to 10 years in prison and a $250,000 fine, Delahanty said. LaCasse will be sentenced after the completion of a presentence investigation report by the U.S. Probation Office.

Court records indicate that on May 23, 2014, LaCasse arranged for another person to buy a 9 mm pistol for him at Ben’s Trading Post in Presque Isle.

LaCasse was at the store when the firearm was purchased and witnesses saw him with the pistol. He admitted to others that he had a gun, Delahanty said.

Additionally, federal agents recovered 9 mm casings and other evidence that LaCasse had used the firearm for target practice. LaCasse was prohibited from possessing firearms because he had felony convictions in Massachusetts in 2009.

The investigation that led to the guilty plea was conducted by the U.S. Immigration and Customs Enforcement’s Homeland Security Investigations, the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Caribou Police Department.
