Massachusetts State Police say a 12-year-old girl from Norton has died following a single car rollover crash on Route 24 in Stoughton late Thursday afternoon.

Three people, all from Norton, were involved in the rollover on Route 24 northbound in Stoughton, according to Stoughton Fire Department dispatcher Joe Sbardella.

The driver and the front seat passenger were both ejected, while the backseat passenger was pulled from the car by a Good Samaritan, according to State Police.

The Boston Herald reports State Police responded to the scene and found all three people lying on the highway. The young girl was pronounced deceased at the scene.

One woman was transported to Boston Medical Center and another woman was transported to Massachusetts General Hospital, according to State Police.

Stoughton Fire Captain Jim Bertram said both women, while semi-conscious, had multi-system trauma with potential life-threatening injuries.

The Stoughton Fire Department responded to the accident at 4:45 p.m. on July 12. The car rolled over just before exit 20 (Route 139) on the northbound side, Sbardella said.

Bertram said the accident took place about a quarter mile south of the Route 139 exit, near the Page Street overpass on the Stoughton/Avon line.

The Randolph and Avon Fire Departments also responded to the scene.

The accident created gridlock on both sides of Route 24 during the evening commute. At one point, traffic was backed up to Route 495 on the northbound side, WBZ reported. The highway reopened Thursday evening, according to the Massachusetts Department of Transportation.

The State Police are investigating the cause of the crash, Bertram said.

Bertram said he has "been to over 100 of [these serious car accidents] and it never gets easier," noting that many of the Stoughton firefighters have young children around the age of the girl who died.

"Wear your seat belt," he cautioned.
