Alexandria Duval is an identical twin and yoga instructor.

Alison rose to fame when her and her twin, Anastasia Duval, opened their yoga studio, Twin Power Yoga, in Palm Beach, Florida in 2008.

In May 29, 2016 shortly after their move to Maui, Hawaii, Alexandria intentionally drove her car off of a cliff with her identical twin, Anastasia Duval, in the car. The car plunged 200 feet in the air before crashing into lava rocks. Anastasia died in the crash, while Alexandria survived and is facing charges of second-degree murder.

Alexandria Duval was found not guilty of killing her sister, Anastasia Duval in January of 2018. She agreed to have the veredict ruled by a judge instead of a jury.

Anastasia's boyfriend Federico Bailey testified in court on Tuesday on the second day of the murder trial, revealing details of Alexandria's behavior in the days after the crash.

'She began cuddling up on me, it seemed like she was flirting with me... she sat down beside me really close and lay her head on my shoulder,' Bailey said.
