PORTLAND — A New Hampshire man on trial for allegedly shooting his wife and her friend in Saco two years ago testified in his defense in U.S. District Court this afternoon.

According to prosecutors, Gregory Owens, 59, of Londonderry, New Hampshire, broke into the home of Steven and Carol Chabot where his wife, Rachel Owens, was visiting, in the early hours of Dec. 18, 2014, and shot Steven Chabot and Rachel Owens.

Both survived the shooting. However, the bullet is still in Rachel Owens’ head, and she is undergoing physical therapy to regain the use of her motor functions.

During his testimony, Owens discussed his relationship with his wife and the problems he said they had in their marriage.

In earlier testimony, Rachel Owens was described as forgetful and frail prior to the shooting.

Rachel Owens was staying with Steven Chabot and his wife Carol – Rachel’s friend – at the time of the shooting. Carol Chabot said she had brought Rachel to her home to provide a break for Gregory Owens.

Prosecutors say Gregory Owens drove to Maine with the intent to kill his wife because he had a mistress in Wisconsin and she had threatened to expose their affair.

He is charged with interstate domestic violence and discharging a firearm during, and in relation to, a crime of violence.

Gregory Owens will continue testifying Friday morning.
