BOSTON, Mass. (WWLP) - The mother-in-law of the deceased Tamerlan Tsarnaev says her family is "sickened" by the horror he inflicted.
Judith Russell's daughter, Katherine, was married to Tamerlan. Judith says her family realizes they never really knew Tamerlan.
The Russell family lives in North Kingstown, Rhode Island.
A neighbor of the family says Katherine began dressing in Muslim garb with head coverings when she returned from college a few years ago.
According to an AP report citing spotcrime.com , Tamerlan was arrested for domestic violence in July 2009 after assaulting his girlfriend.
