Episode 1: Twisted Sisters, a tale of yoga and death

Ali and Ann Dadow (Thomas Cordy/West Palm Post)

Ann and Alison Dadow were as close as two sisters could be. Or closer. They did everything together. They changed their names together, to Anastasia and Alexandria Duval. They taught yoga together, moved across the country, drank, fought and even filed for bankruptcy together. Everything, that is, until their car went over a cliff in Hawaii during a hair-pulling brawl and one died and the other was charged with murder.
