Police say three people connected to one of the roommates returned to the home, identifying themselves as police officers early Friday before attacking the victim in his RV.
The three are due to be arraigned Monday.
Police charged 53-year-old Ralph Doucette and 43-year-old Paul Carbonneau of Lowell, Mass., with burglary, assault and impersonating an officer. Charged with first-degree assault and burglary was 57-year-old Cynthia Nagele, of Lowell. All three remained jailed Saturday. It was unclear if they’d retained lawyers.
Police say the victim, who wasn’t identified, dialed 911 during the attack. His injuries were described as serious.
