Benoit’s lawyer told reporters his client was arguing with his girlfriend over the music volume during a party at the trooper’s home.

“She kissed him and bit him really hard on the lip and on the neck — you saw the marks,” Benoit’s attorney said. “He pushed her away, she hit the wall, and apparently broke her collarbone.”

According to the police report, the girlfriend’s mother said Benoit ‘went crazy’ and started breaking things.

The report also states Benoit had apparently caused damage inside his home, including broken dishes, broken wall, and damaged railings. Other off-duty state trooper’s who were at the scene restrained him.

The woman was taken to Heywood Hospital in Gardner and has since been released. She did not file a restraining order against Benoit.

Benoit, a 10-year veteran, is a member of the Division of Field Services and is stationed in Troop C, which oversees central Massachusetts.

State Police took the trooper’s service weapons and ammunition, cruiser, State Police identification, and other job-related equipment.

Several privately-owned weapons and ammunition were also removed from his home by police.

His license to carry a firearm will be suspended indefinitely.

Benoit is being held without bail pending a dangerousness hearing on Wednesday.
