Federal Jury Convicts Hebron Man of Being a Felon in Possession of Firearms

PORTLAND, Maine — A Hebron man was found guilty today of being a felon in possession of firearms following a two-day jury trial in U.S. District Court in Portland.

According to evidence presented during the trial, in January 2022, Maine State Troopers executed search warrants at the home of Dario Giambro, 75. Investigators located hundreds of firearms, including shotguns, rifles, pistols and revolvers, and a large amount of ammunition inside Giambro’s residence. Giambro is prohibited from possessing firearms due to a prior federal conviction in the District of Maine for possessing an unregistered firearm, a felony offense.

Giambro faces up to 10 years in prison, a fine of up to $250,000 and up to 3 years of supervised release. He will be sentenced after the completion of a presentence investigation report by the U.S. Probation Office. A federal district judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

The Bureau of Alcohol, Tobacco, Firearms and Explosives and the Maine State Police investigated this case, with assistance from the Oxford County Sheriff’s Office and Norway Police Department.
