(Scroll down for video) A yoga instructor was arrested on a charge of murder after allegedly killing her twin sister by deliberately driving a car off a cliff, according to police in Hawaii.
Maui police said that they have arrested 37-year-old Alexandria Duval, after being accused of killing 37-year-old Anastasia Duval.
Alexandria was charged with one count of murder. She was booked into jail, where she is being held without bail.
Alexandria denied the allegations, saying it was an accident.
Witnesses told police that they saw the identical twin sisters fighting inside their Ford Explorer moments before the vehicle flew off the cliff.
They saw Anastasia pull the hair of her sister before the car sped forward.
Alexandria seemed angry, and the airbag control module of the vehicle showed that the brakes were not used before the car accelerated.
While speeding towards the cliff, Alexandria assaulted her sister. Alexandria was arrested at her hotel on Friday.
