BROOKS, Maine — A woman died after her car flipped over on Route 7 on Tuesday night.

It’s unclear what happened that caused Gracia Berrocal, 64, of Jackson to lose control of her car. Police are investigating the crash.

“She rolled and was injured in the roll. We don’t have details on it. She went off the road for whatever reason — we’re not sure why. A medical issue or she fell asleep — we don’t know,” said Deputy Chief Jeff Trafton at the Waldo County Sheriff’s Office.

Berrocal was the only person in the car. It’s unclear if her car struck anything.

No other details were available Wednesday.
