STAMFORD, N.Y. - A woman who had been accused of killing her twin sister after their vehicle plunged off a Hawaii cliff has been released from a New York jail where she was being held on drunken driving charges.

Delaware County authorities say 38-year-old Alexandria Duval was released Friday after posting bail.

Duval was arrested Aug. 15 in Stamford. State police said her blood-alcohol content was more than three times the legal limit.

Duval pleaded not guilty Aug. 23 to charges including aggravated driving while intoxicated.

Messages left with her attorney weren't returned.

Duval's sister, Anastasia, died in May when their SUV crashed in Maui and plunged 200 feet.
