HONOLULU — A Maui woman who was driving a vehicle when it plunged off a cliff is charged with murder in the death of her twin, who was in the passenger’s seat.

Prosecutors say Alexandria Duval, who is also known as Alison Dadow, intentionally caused the death of her sister, Anastasia Duval, also known as Ann Dadow.

The 37-year-old sisters were traveling on Hana Highway when their Ford Explorer crashed into a rock wall last week. Police say the Explorer fell about 200 feet.

Anastasia Duval was pronounced dead at the scene. Her sister was taken to a hospital in critical condition.

Alexandria Duval was arrested Friday. She’s scheduled to appear in court Monday.

According to probable cause documents filed in court, a witness reported that the driver appeared to be in a rage. He and other witnesses saw the two women arguing, with the passenger pulling the driver’s hair.

The documents say the vehicle’s air-bag control module shows the driver didn’t attempt to brake before accelerating, making a hard left and crashing into a wall.

Police arrested Alexandria Duval on Friday because they found out she was trying to leave the state.

Alexandria Duval’s defense attorney says she wasn’t trying to harm herself or her beloved sister.
