A Saco man faces more than 15 years in prison as an armed career criminal after he pleaded guilty to federal charges of being a felon in possession of a handgun.

Charles H. Casey Jr., 39, pleaded guilty today in U.S. District Court in Portland. Casey was arrested June 17 by Saco officers after he fired a Taurus .22-caliber handgun inside his apartment on Washington Avenue.

A 26-year-old woman told police that during a dispute at about 8 a.m., Casey fired a shot from a semi-automatic pistol into an interior wall. Nobody was injured, but Casey was seen walking in the area with a gun tucked into the waistband of his pants.

Casey has multiple criminal convictions including three convictions for burglary – a felony. Because of that, he will be sentenced as an armed career criminal. Federal law requires that he be sentenced to at least 15 years and up to life in prison. He also faces a fine of $250,000 and will be on supervised release for five years after getting out of prison.

The case was investigated by Saco police and the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives as part of the U.S. Attorney’s Project safe Neighborhoods initiative.
