SACO, Maine — A New Hampshire man already facing federal charges for allegedly driving to a Saco home in December and shooting his ailing wife and another man has been indicted by a York County grand jury on 13 felony counts, including aggravated attempted murder and elevated aggravated assault.

Gregory Owens, 58, of Londonderry, New Hampshire, was indicted in March on federal charges of interstate domestic violence and discharging a firearm during and in relation to a crime of violence.

Owens was indicted earlier this month by a York County grand jury on four counts of Class A aggravated attempted murder; two counts each of Class A attempted murder, elevated aggravated assault and elevated aggravated assault with indifference; two counts of Class B aggravated assault with a weapon; one count of Class A burglary with a firearm; and one count of Class D criminal mischief.

Saco police went to a home at 25 Hillview Ave. just before 3 a.m. Dec. 18, after a man called to say he had been shot by an intruder and was hiding in a closet in the home. Police were informed there might be other victims in the house.

Police found Owens’ 55-year-old wife, who was staying with the Saco couple for a few days, suffering from multiple gunshots. Officers also found a man suffering from gunshot wounds in the residence.

Both were taken to Maine Medical Center and survived “serious” injuries.

According to an affidavit by Special Agent Pamela A. Flick of the FBI, the homeowners awoke to the sound of breaking glass. The woman barricaded herself in a bedroom while the man went into the hall and allegedly saw a man wearing a ski mask and carrying a handgun.

Prosecutors say Owens, a retired U.S. army sergeant major trained as an expert marksman, then went to the bedroom where his wife was sleeping and shot at her four times, striking her body three times, including one bullet to the back of her head.

He then allegedly returned to the bedroom where the male homeowner was and shot him through a closet door, striking him three times in the arm.

Flick wrote Owens drove from the Londonderry, New Hampshire, home he shared with his wife of more than 35 years to Saco that night, intending to kill her.

A subsequent investigation involving the FBI, the Saco Police Department, the Maine State Police, the New Hampshire State Police and the Bureau of Alcohol, Tobacco, Firearms and Explosives allegedly revealed that Owens’ wife had become “suddenly and inexplicably ill” during 2014 and began showing signs of dementia. Owens reportedly had been asking friends to help with her care because she was unable to care for herself.

New Hampshire state troopers stopped Owens later in the morning of Dec. 18 in Londonderry to notify him his wife had been shot. Owens then allegedly told police several different stories about the night before.

Police allegedly seized 26 firearms from the New Hampshire house, as well as other evidence prosecutors say points to Owens as the perpetrator, according to court documents.

Owens pleaded guilty to the federal charges in March and remains in the custody of U.S. marshals. He is scheduled to be ready for trial July 6, according to court documents.

Additional information about the state charges was not available Saturday.
