Crime stories with Nancy Grace on Sirius XM Triumph channel 132.

Did a yoga star intentionally murder her gorgeous identical twin sister?

We are going live in a trial that has just kicked off. Did a woman murder her twin sister by

driving her off a cliff intentionally killing her by plowing their SUV over a 200-foot cliff in

Hawaii. Well, that is what a judge will determine. Alexandria DuVal, the case, has just started on trial

for the murder of her sister. The two big hits in the yoga scene with their own private studio,

they had so many customers they had to add on classes. How did everything go so wrong? I'm Nancy

Grace. This is Crime Stories. Thank you for being with us. Joining me right now, Dr. Bethany Marshall,

Los Angeles Psycho Analyst Cheryl McCollum, Director of the Cold Case Research Institute.

Boy do we need her today. Also with me, Crime Stories Investigator reporter Scott Kimbler.

Let's just start with that. But before we get to one sister dying at the foot of the cliff,

can we talk about their success together, their success story?

Yes, Nancy. These two have been running a yoga studio for quite some time. They only moved to Hawaii

in 2015. Before that, they ran a successful yoga studio, Plural and Florida. The sisters were

known to be somewhat volatile. They were also very popular yoga instructors in Florida and in Hawaii.
