A Raymond woman was killed in a car crash in Harrison when her speeding car hit a frost heave on a curve, sending the car flying, according to police.

The wreckage was not discovered until Wednesday morning but the accident most likely happened at about 9 p.m. Tuesday.

A passing motorist notified the Cumberland County Sheriff’s Office of a car off the road in the yard of 510 Naples Road just after 6:30 a.m.

Emergency workers responded and pronounced Sabrina B. Titus, 28, dead at the scene.

The sheriff’s office is still investigating, but it appears that Titus was driving a 1999 Chevrolet S-10 Blazer north on Naples Road when it hit a frost heave just north of the Carsley Road intersection, causing her to lose control. The SUV hit a snowbank, went airborne, then hit a rock wall before rolling into a tree, demolishing the car.

It took firefighters two hours to remove her from the car. When rescue workers discovered two car seats in the vehicle, they worried that children might have been inside. But authorities contacted the father of the children, who said they were with him.

The residents of 510 Naples Road told deputies they heard a loud crash Tuesday at 9 p.m. but when they went outside to investigate, didn’t see anything, said Capt. Don Goulet. The area is very rural and the car was in trees at the edge of a large, unlit yard about 70 feet from the house.

The force of the crash killed the woman instantly, Goulet said.

The car was going significantly faster than the posted 40 mph speed limit, but the accident reconstruction is not complete and a final speed has not been determined, he said.
