A 26-year-old Fort Fairfield woman is in the hospital with serious injuries after a single-vehicle crash Tuesday night on Route 1 in Westfield.

State Police say Lili Parady and her 8-year-old daughter were traveling south around 9 p.m. when Parady lost control of her 2009 Toyota Camry on a turn. The car went off the road and struck a large tree just north of the Miller Road intersection.

Police say Parady's daughter was able to free herself from the wreckage and flag down a passing motorist, who called 9-1-1.

Corporal Chuck Michaud and Troopers Jared Sylvia, Tim Saucier, and Rob Flynn of the Maine State Police responded to the crash, as did the Aroostook County Sheriff's Office.

The Mars Hill Fire Department extricated Parady from the car using hydraulic cutters, Cpl. Michaud said. The woman and her daughter were both transported by Crown Ambulance to The Aroostook Medical Center in Presque Isle.

Parady was flown to Eastern Maine Medical Center in Bangor where she remained in critical condition Wednesday evening.. Her daughter was treated for minor injuries at TAMC and released.

The cause of the crash remains under investigation and it is unclear why Parady failed to negotiate the turn. Police say she was not wearing her seat belt. It appeared her daughter was in the back seat and was wearing her seat belt.

The  vehicle was demolished in the crash.
