Surviving Twin to Fight Extradition to Hawaii Over Sister's Death

Alexandria Duval had an extradition hearing this morning.

— -- A woman accused of murdering her twin sister by driving their vehicle off a cliff in Hawaii plans to fight her extradition to the Aloha State.

Alexandria Duval, who was born in upstate New York, appeared in Albany County Court just after 9 a.m. today for an extradition hearing. The 38-year-old defendant was escorted into the courtroom wearing shackles and a yellow jumpsuit.

Terence Kindlon of the Albany County Public Defender’s Office, who is representing Duval, said his client will not go back to Hawaii willingly. Duval returned to New York to mourn her sister's death, according to Kindlon.

"She was not running from anything," Kindlon told reporters after the hearing.

Duval is due back in court on Dec. 16. It was unclear if she has entered a plea.

New York State Police said Duval was arrested on Nov. 11 after she was located at a residence in Albany. Police said Duval attempted to flee before she was taken into custody. She was being held in Albany County Jail awaiting extradition, with bail set at $3 million, according to ABC affiliate WTEN in Albany.

Prosecutors say Duval intentionally caused the death of her identical twin sister on May 29 when she allegedly drove their SUV off the ocean-side Hana Highway in Maui. Duval survived with critical injuries, while her sister Anastasia was pronounced dead at the scene.

Witnesses said they saw the twins violently arguing moments before the driver seemed to suddenly accelerate and make a sharp left turn. The vehicle then slammed into a rock wall and plunged 200 feet to the rocks below, according to ABC affiliate KITV in Honolulu.

A grand jury in Hawaii indicted Duval on that charge last month and Maui police issued a warrant for her arrest.
