North Andover Man Pleads Guilty to Manslaughter

Thomas Belanger, 22, of North Andover, pleaded guilty to manslaughter today in Salem Superior Court for the February 6, 2008, stabbing death of his psychotherapist, Diruhi Mattian, of Wilmington.

Judge John Lu sentenced Belanger, who has a history of psychiatric issues, to 14-15 years in state prison.  

Essex First Assistant District Attorney John T. Dawley told the court that on the day of her death, Mattian went to Belanger’s residence after receiving a call concerning a family dispute.  She had been treating the family in mental health home visits for a few years.

When Mattian arrived she attempted to mediate the dispute.  Belanger then stabbed her with a knife,  and then slit his own throat, requiring extensive hospitalization.

Mattian had been employed by Family Continuity of Lawrence.

Belanger was represented by Attorney James Krasnoo.
