PORTLAND – A Greenwood man will spend 10 years in federal prison for being a felon in possession of ammunition, U.S. District Attorney Paula D. Silsby announced Tuesday.

Everett Chase, 46, had prior convictions of unlawful sexual assault and burglary when he was arrested Feb. 26, 2006, after a police chase. Police recovered an antique firearm and several rounds of ammunition.

Chase pleaded guilty to being in possession of ammunition last November, and was given the maximum sentence for it Tuesday.

Chase still faces charges in state court stemming from the Feb. 26 arrest when police say he kidnapped his estranged wife in the presence of their six children, assaulted her and threatened her life with a handgun.

Maine State Police headed up the investigation, along with the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives.
