A 28-year-old woman died Thursday evening after being pinned against a tree outside her house by a sport utility vehicle, police said.

Robynapril R. Maguire was pronounced dead at the scene. No foul play is suspected, but police are working to determine what caused the accident, police said.

Police and paramedics were dispatched to 222 Center Road about 6:35 p.m., police said. They found a white 1999 Ford Explorer on the lawn with the driver's door open.

Maguire was pinned between the side of the vehicle and a tree. Maguire was backing out of her driveway when the accident occurred, police said. The driver's door was open and Maguire was mostly outside of the vehicle, police said.

Her roommate called police and paramedics, who pronounced her dead. The woman's husband, who also lives at 222 Center Road, and the roommate were hospitalized for emotional trauma, police said.
