LOWELL, Mass. (AP) — A former Massachusetts State Police trooper convicted of raping his ex-girlfriend has been sentenced to up to 15 years in prison.

The Middlesex district attorney says Robert Sundberg was sentenced Tuesday in Lowell Superior Court.

The 48-year-old Framingham resident was convicted by a jury last week of multiple charges, including rape, strangulation, assault and battery, and stalking.

He was arrested after the victim, who is also a state police employee, reported she was attacked at their Boxborough home in April 2016.

Prosecutors said Sundberg had a history of abuse directed at the victim.

Sundberg, a 14-year veteran of the agency, was suspended without pay after his arrest and fired soon after his conviction.
