QUINCY - A Duxbury police officer has been charged with domestic violence after police said he beat up his girlfriend, a police officer from Milton, and pointed a gun at her head, in what police called a case of ongoing abuse.
Police said that Officer Sean P. Moran, 30, smashed his girlfriend's head against a metal fence after an argument Saturday morning.
A month earlier, he had pointed her service weapon at her head, police said. He told his girlfriend, whose name was not released, that he would kill himself if she ever told anyone, so the woman did not complain until after the assault Saturday, police said.
Moran, who has been on the force for nearly two years, was arrested without incident at his home in Quincy Saturday morning.
He was charged with domestic assault and battery, assault and battery with a dangerous weapon (the fence), assault with a dangerous weapon (a gun), threatening to commit a crime, and malicious damage to personal property.
He was held at the Quincy police station without bail and is to be arraigned today in District Court in Quincy.
Quincy Police Chief Robert F. Crowley said his department was notified about 2:24 a.m. Saturday after the woman, 28, drove to her mother's home in Milton and called that town's police chief, Richard G. Wells Jr.
Wells contacted Quincy police, who interviewed the woman at her mother's home. Later, they arrested Moran.
The woman told police that she and Moran had been at a party at the Common Market restaurant in Quincy Friday night into Saturday morning when they argued. They went outside into the parking lot, and Moran allegedly banged her head into the metal fence adjacent to the restaurant.
The woman told police Moran grew more violent when they were in her truck driving toward his house, and at one point he damaged the dashboard, Crowley said. Police did not say how.
When they reached the home, the woman grabbed her dog as if she were taking it for a walk and fled to her mother's house, she told police.
Crowley said police in Duxbury were notified. Duxbury Chief Mark M. DeLuca did not return a call for comment, but Crowley said he was told that Moran's service weapon had been confiscated and was at the Duxbury police station.
