A woman is dead after a single-car crash on Route 495 southbound in Franklin, Massachusetts, according to State Police.
The accident occurred around 12:15 Sunday, just before exit 17. A preliminary investigation reveals that 30-year-old Crystal Legassey of Oxford, Massachusetts, lost control of her Ford Fusion and hit a guardrail, causing the car to rollover.
The impact of the crash was so great that the driver's sister, 31-year-old Ashley Hartung of Whitinsville, Massachustts, was instantly killed and the guardrail split.
Legassey was taken to UMass Medical Center with minor injuries.
The cause of the accident remains under investigation.
