A woman has been charged with second degree murder after the car she was driving plunged 200 feet off a Hawaiian motorway onto the rocky shoreline below, killing her twin sister.

Alexandria Duval, formerly known as Alison Dadow, has been accused of intentionally causing the death of her identical twin sister, Anastasia Duval, who was formerly known as Ann Duval.

The sisters, 37, were travelling in a white Ford Explorer when the car collided with a rock wall on the Makai side of the Hana Highway, falling down the side of the cliff. Anastasia was pronounced dead at the scene and left Alexandria in a critical condition. She was airlifted to hospital.

Witnesses cited in court documents said the driver of the car appeared to be in a rage before the crash happened, while the passenger was apparently pulling the driver’s hair during an argument seen while the car was stationary, the Associated Press reports.

The car was also seen accelerating forward and making a sharp left over the cliff, Maui Deputy Prosecuting Attorney Emlyn Higa said, while the car’s air-bag control module shows the driver did not make an attempt to break before accelerating and hitting the rock wall.

After Alexandria was discharged from hospital she attempted to leave the state and was arrested by police.

Mr Higa said in the court documents: “We had information after she was discharged from the hospital she attempted to fly out of the jurisdiction on Friday night.

“All we know is she was trying to leave the state,” he said. “We were afraid she would try to leave the country as well.”

Alexandria was arrested on Friday night and appeared in court on Monday with her arm in a sling, where a judge ordered her to be held without bail.

Todd Edins, Alexandria’s defence attorney, said she “did not try to harm herself or the person she most loved and was closest to in the world”. He referred to her using her former name of Alison, though both sisters had registered their address and driving licenses under their new name of Duval.

The twins were known for their yoga business in Florida, Twin Power Yoga, which they ran under the names Ann and Alison Dadow. In December 2014 the pair reportedly left Florida to move to Utah.

They were reported to have relocated to Hawaii in January this year, when Anastasia apparently appeared at a homeless shelter in Maui.
