The strange story of Alexandria Duval got stranger last week when she was arrested — again — in her twin sister’s death. Authorities allege that Duval (née Alison Dadow) drove her and her sister off a cliff in Hawaii on May 29, injuring herself and killing her twin, Anastasia Duval (born as Ann Dadow).
The fatal crash this summer reportedly capped off years of business ventures, bankruptcies and moves for the sisters, who first made a name for themselves as yoga instructors in Florida. Alexandria’s attorney has called the murder allegations “extreme and cold-hearted.”
Here are five things you need to know about the case.
1. Alexandria Was Charged with Anastasia’s Murder Before — and Released
Soon after the fatal crash, Alexandria was charged in early June with second-degree murder in Anastasia’s death. Police accused her of intentionally driving the SUV off the road. Almost immediately, however, a judge tossed out the murder charge after ruling there wasn’t enough probable cause.
“We cross-examined them. They presented their evidence and the judge essentially found that there was not enough evidence to sustain the charge,” Alexandria’s attorney, Todd Eddins, reportedly said at the time.
It remains unclear what new evidence may have come to light before Alexandria’s second arrest (prosecutors could not immediately be reached). But the Maui News reports that the new murder charge is the result of a grand jury’s decision in October.
As of Nov. 11, Alexandria was awaiting extradition to Hawaii from Albany, New York, where she was arrested that same day, police said in a statement. She will not enter a plea until she is extradited.
2. Witnesses Allegedly Saw a Fight in the SUV Before the Crash
A motive remains unclear in the alleged murder. But before their vehicle plunged 200 feet off a cliff in Hana, Maui, witnesses reported seeing the Duval sisters fighting with each other, with the passenger pulling the driver’s hair, officials alleged, according to the Associated Press.
“Witnesses told police that two women were arguing in the parked vehicle when the driver apparently drove the vehicle into a rock wall on the side of the roadway and off the sheer cliff,” according to the Star-Advertiser.
Witnesses also said that they saw the vehicle allegedly “accelerate forward and then take a sharp left over the cliff,” one prosecutor said.

3. Defense Attorney: ‘This Is a Devastating, Heart-Shattering Tragedy’
Eddins has not confirmed to PEOPLE that Alexandria was driving the SUV at the time of the crash, but he previously said, “The sisters had an exceptionally close bond even by identical twin standards.”
“This is a devastating, heart-shattering tragedy for Alison and her family,” Eddins said in June. “We will explore all avenues to combat a charge that, in our view, is extreme and cold-hearted.” (Eddins declined to comment to PEOPLE on Alexandria’s second arrest.)
4. The Sisters Were Well-Known Yoga Instructors
The Duval sisters were reportedly born Alison and Ann Dadow in New York state, but they came to prominence as yoga teachers in Palm Beach, Florida, where they ran multiple locations of their yoga studio starting in 2008 and even produced an instructional DVD.
Still, they may have lived beyond their means (and their success), according to one local expert: “They were very well respected here for a while,” South Florida gossip columnist Jose Lambiet told the Star-Advertiser. “But when you get successful, it’s easy to start overspending. This is Palm Beach. Once you start shopping on Worth Avenue, it can get out of control pretty quickly.
Such financial woes could have been at play when the sisters abruptly closed their yoga studios in Florida and moved across the country — the first in a series of decisions that would take them, ultimately, to Hawaii and the scene of the summer’s deadly crash.
5. The Sisters Reportedly Filed for Bankruptcy Several Times and Had New Names
After leaving Palm Beach, the Duval sisters appeared in Park City, Utah, where they opened a new yoga studio, according to the Star-Advertiser.
They both filed for bankruptcy in 2014, according to the paper, saying they had hundreds of thousands of dollars in debt. Lambiet told the Star-Advertiser the pair traveled to Maui in December 2015.
Police said both sisters had Hawaii driver’s licenses, with their Duval names, at the time of the crash. But PEOPLE has not been able to confirm if the sisters legally changed their names.
