The former manager of an Auburn-based group home for people with developmental and intellectual disabilities has been sentenced to six months in jail for stealing from the nonprofit and at least one client. Terri Arsenault of Mechanic Falls was sentenced Wednesday after pleading guilty last month to two felony theft charges. Prosecutors say she used the John F. Murphy group home’s credit card to buy gas, groceries and other household goods, and to take her daughters on an outing to Boston. She also hired her husband’s construction company to do work that was never done. The Sun Journal, reports that a tearful 41-year-old Arsenault apologized in court and said she was “ashamed” of her actions. She was sentenced to two years of probation and has paid $15,000 in restitution.
