Yoga teacher found not guilty of murdering twin sister

A yoga instructor was found not guilty on Thrusday of killing her twin sister in a fatal car crash in Hawaii.

Judge Peter Cahill acquitted Alexandria Duval of second degree murder in the 2016 death of her sister Anastasia Duval.

Alexandria Duval was driving down a narrow winding highway with Anastasia in the passenger seat when their SUV plunged 200 feet over a cliff.

Anastasia died at the scene, while Alexandria sustained minor injuries.

While the twins ran a popular yoga studio together and drove matching Porsches, witnesses told the court their relationship was a turbulent one.

Anastasia’s boyfriend Federico Bailey said the twins frequently attacked each other, throwing punches as they “fought like soldiers.”

And witnesses who saw the SUV shortly before the crash said the passenger was pulling the hair of the driver.

While prosecutors said Alexandria intentionally tried to hurt or kill her twin, the defense argued the crash was a tragic accident.

Wayne Slagle, an accident reconstructionist and engineer who was called to the stand as a defense witness, said, “I think this is consistent with somebody trying to find the brake and not able to do it.”

“It’s not consistent with somebody five seconds before, or even four seconds before, trying to put it to the floor, trying to go over a cliff or rock wall,” he added.

Bailey paid tribute to his girlfriend less than two months after her death and wrote on Facebook, "May the world discover he truth of what happened to you...”

He testified on Tuesday, saying he was on a camping trip with the twins when another one of their fights broke out.

At one point, Alexandria said she was driving her sister to the bathroom up the hill, but the two disappeared for four hours.

They returned, spoke to Bailey, before disappearing again when he was in the bathroom.

With the twins still gone the next morning, Bailey hitchhiked back to his home, where Alexandria turned up at around 3:30 p.m. and delivered news of the crash.

She didn’t have any answers when he inquired about what happened.

Instead, she wanted him to help wash her hair, Bailey said.

“She was flirting with me, and she was cuddling on me,” he said.
