MADISON, Maine — A South China woman suffered serious injuries Tuesday when the minivan she was driving left Route 201, struck a driveway and then went airborne before rolling over several times.

Shanya Pottle, 20, Pottle suffered serious head injuries, along with possible broken bones, and was unconscious when rescue units arrived, Chief Deputy James Ross of the Somerset County Sheriff’s Office said in a news release.

Because of the extreme damage to the vehicle, a 2005 Dodge Caravan, the Madison Fire Department had to use the Jaws of Life to extricate Pottle from the wreckage.

Pottle was initially taken by ambulance to Redington-Fairview General Hospital but later was transferred to a Portland hospital because of the nature of her injuries, Ross said.

A white Labrador retriever that was in the vehicle was ejected and has not yet been located, Ross said. He said the dog did not appear to be injured.

According to Ross, the crash happened about 11 a.m. about a mile north of Lakewood Golf Course.

A truck driver who passed Pottle moments before the crash, and who witnessed it, told deputies that it appeared Pottle may have been using a cellphone when she passed him.

According to the witness and evidence deputies saw at the crash site, the minivan swerved in its lane and temporarily regained control before veering off the right side of the road. The vehicle then struck a driveway and went airborne at which time it rolled over several times before coming to a stop, Ross said.

Distracted driving is being investigated as a possible cause of the crash, Ross said. He said no further information was available Tuesday and that the crash remains under investigation.
