ALFRED — A New Hampshire man accused of breaking into a Saco home and shooting his wife and the homeowner in December has pleaded not guilty to 14 charges after being indicted last month by the York County grand jury.

Gregory Owens, 58, of Londonderry appeared in York County Superior Court in Alfred on Thursday for the first time since being indicted on April 8.

Justice John O’Neil Jr. ordered that he remain held on the same $2 million bail amount set on Feb. 5, when Owens was first brought to the state court on a charge of aggravated attempted murder.

He was indicted on that initial charge and 13 additional charges, including three more counts of aggravated attempted murder, two counts of attempted murder, four counts of elevated aggravated assault, two counts of aggravated assault, one count of burglary and one misdemeanor count of criminal mischief.

The state charges are in addition to charges Owens already faces in U.S. District Court in Portland. Owens pleaded not guilty to federal charges of interstate domestic violence and firing a gun in a violent crime. He has been detained under a federal court order since his arrest on Jan. 12.

Owens faces up to life in prison on the federal charges. He also faces up to life in prison on the four state charges of aggravated attempted murder.

Owens is a former Army marksman who prosecutors say tried to kill his wife during a staged break-in after his jealous girlfriend in Wisconsin threatened to expose their affair.

Police say Owens broke into the home of Steve and Carol Chabot on Hillview Avenue in Saco on Dec. 18 wearing a ski mask and armed with a 9 mm pistol. They say he shot his wife, Rachel Owens, 55, who was staying at the house. She was shot three times, including once in the head. Steve Chabot was shot three times in the torso through his bedroom door.

A court affidavit prepared by Saco police Detective Frederick Williams said the Chabots heard a struggle coming from the room where Rachel Owens was sleeping just before the shooting.

Carol Chabot “heard thrashing, screaming and then crying, followed by gunshots and moaning,” the affidavit said.

Carol Chabot said that their friends did not like Gregory Owens because he was arrogant and sometimes belittled his wife. Carol Chabot described him as “cold and hard, very opinionated, odd, a loner,” the affidavit said. She said he owned several guns that he would show off after consuming alcohol, and that he said he had killed people while in the military.

Gregory Owens described himself as the chief executive officer of a civilian company that trains military personnel, Carol Chabot told investigators. Spokesmen for two of the security and defense-related companies Owens has worked with, Target Acquired LLC and Laser Shot, said after his arrest that he was not a current employee and had not worked for them for some time.

On the day of the shooting, police pulled over Owens in Londonderry. Police saw blood in the car and clothing that matched that of the intruder at the Chabot home.

Owens told investigators that day that he had been watching television, then worked late on a project, a contract to work with troops in the Ukraine, the affidavit said. He told them he had stayed in town all night working, but his computer showed that he had changed the clock manually to make it appear as though he had been working on it at the time of the shooting, when he wasn’t.

Police obtained a search warrant and seized several items they say link Owens to the crime, including DNA from blood from an open cut on his arm and DNA taken from a broken window at the Chabots’ house.

If he does not post bail, Owens will be held by federal officials until his next appearance in federal court, set for Monday.

Steve Chabot and Rachel Owens, who is originally from Saco, were both hospitalized with serious wounds, but survived.
