Woman Once Suspected of Killing Twin Sister Pleads Not Guilty to DWI

Alexandria Duval, 37, appeared in Stamford Town Court one week after she allegedly came close to hitting a New York State Police investigator's vehicle.

The Hawaii woman once suspected of killing her twin sister pleaded not guilty on Tuesday to multiple charges in connection to a drunken driving arrest in upstate New York, authorities said.

Alexandria Duval, 37, appeared in Stamford Town Court one week after she allegedly came close to hitting a New York State Police investigator’s vehicle as she swerved on State Route 23.

After being pulled over as she drove onto Main Street in the Village of Stamford, Duval took a breathalyzer test that showed she had a blood alcohol content of 0.26 — more than three times the legal limit, police said.

She was not wearing a seat belt and refused to be fingerprinted, photographed, or say where she lives, cops said.

Duval pleaded not guilty to aggravated driving while intoxicated, obstruction of justice and numerous traffic violations.

A judge approved tripling Duval’s bail from $5,000 cash or $10,000 bond to $15,000 cash or $30,000 bond after authorities learned a warrant was out for the former yoga instructor’s arrest following a DWI charge in Summit County, Utah.

Duval allegedly paid her bail in that case and then fled the state, Delaware County Assistant District Attorney John Hubbard told WBNG.

Duval made headlines in May when the Ford Explorer she was driving on Maui’s Hana Highway slammed into a rock wall and plummeted 200 feet to a rocky shoreline below the road, killing her twin sister, Anastasia, who was sitting in the passenger seat.

Witnesses claimed the two women had been violently arguing before the car careened off the road. Investigators alleged Duval deliberately caused her sister’s death and she was charged with second-degree murder. A judge later ordered her release due to a lack of evidence.

Prosecutors in Hawaii said they planned to search for further evidence in the case.

The twins did most things together — including running two successful Twin Power yoga studios in Palm Beach County, Florida from 2008 to 2014 — but were reportedly often at odds.

“They had a rage problem, an anger problem [and] were arrested several times with anger incidents involving even the police,” gossip columnist Jose Lambiet told Inside Edition at the time.

Duval, who suffered injuries in the crash, returned to her hometown in upstate New York to recover.

She remained in Delaware County Jail on Wednesday. She is next expected in court on August 30.
