A Maui woman who was driving a vehicle when it plunged off a Maui 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.

Hawaii News Now reports witnesses saw the women arguing and that the passenger was pulling the driver's hair.
