BANGOR, Maine — A Caribou man was sentenced to 35 months in prison for unlawful possession of firearms by a prohibited person during a hearing before Judge John Woodcock Tuesday in U.S. District Court.

George D. LaCasse, 35, also was ordered to undergo three years of supervised release upon completion of his prison term, U.S. Attorney Thomas E. Delahanty II said in a news release.

LaCasse pleaded guilty on April 11, according to a previously published report.

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

LaCasse was at the trading post when the firearm was purchased and witnesses saw him with the pistol. He admitted to others that he had a gun, court documents stated.

In addition to the pistol, 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 conviction was conducted by the U.S. Immigration and Customs Enforcement’s Homeland Security Investigations, along with the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Caribou Police Department.
