PORTLAND — Gregory Owens has pleaded not guilty to federal charges of interstate domestic violence and discharging a firearm during a crime of violence in relation to a December home invasion at Hillview Avenue in Saco.

Owens pleaded not guilty to the charges in U.S. District Court on Wednesday, according to court documents.

Owens, 58, of Londonderry, New Hampshire, also faces a state charge of attempted aggravated murder in relation to the early morning shooting of his wife, Rachel Owens, 55, and family friend Steven Chabot, 55, at Chabot’s home in Saco on Dec. 18 .

The two were hospitalized but survived the shooting, according to reports from other media sources.

Rachel Owens, who has dementia, was staying with Steven Chabot and his wife, Carol, to give her husband a break from caring for her, and because she was depressed and her friends thought she needed some cheering up, according to police and FBI reports.

According to FBI reports, Gregory Owens is a retired U.S. Army sergeant and an expert marksman. He has had an ongoing affair since 2008 with a woman in Wisconsin, and his girlfriend had recently threatened to make their relationship public, according to FBI reports.

Boots seized from Gregory Owens’ car matched impressions from footprints in a flower bed at the Chabot residence in Saco, FBI reports said. Clothing taken from Gregory Owens’ washing machine match the description of clothing worn by the Saco home intruder, according to the reports.
