A 17-year-old girl has died after the car she was driving went off the interstate and crashed into several trees on Friday afternoon, state police said.

The driver, identified as Lillianna Cawthron of Londonderry, was taken by ambulance to Elliott Hospital in Manchester with life-threatening injuries, state police said. She later died at the hospital.

At 2:47 p.m. Friday, state troopers were dispatched to a crash near mile maker 14 on Interstate 93 southbound.
