BRUNSWICK — A Brunswick woman was charged with child endangerment after a car crash that left a 5-year-old girl with head injuries, and a teenager faces a charge of pushing an officer responding to the crash.

The girl’s injuries aren’t believed to be life-threatening. She wasn’t secured in a child seat when the car crashed and rolled Saturday, according to Brunswick police Cmdr. Thomas Garrepy.

When officers arrived at the crash on Maquoit Road just after 7 p.m., witnesses said people had run from the car, which Garrepy said was likely the driver and other family members returning to their nearby home after righting the vehicle.

Shannon Pinette, 39, was charged with endangering the welfare of a minor. The cause of the accident is still under investigation, but drugs or alcohol were not involved, Garrepy said.

When police when to the home to question Pinette, a 16-year-old got involved and allegedly pushed a responding officer, Garrepy said. Police say that sparked a scuffle as officers tried to restrain the teen.

“It was a fight from there on out,” Garrepy said.

More officers and two firefighters prevented others at the house from getting involved, and helped restrain the teenager, Garrepy said.

One officer was treated at Mid Coast Hospital for a sprained wrist but is now back at work. Two other officers suffered minor bumps and bruises.
