A woman has been acquitted in the death of her identical twin sister. Alexandria Duval hugged her lawyer before putting on her shades and leaving the courtroom. She had been accused of deliberately driving her SUV off a cliff in Hawaii, resulting in the death of her twin sister Anastasia. Both women were yoga instructors, and a witness reported seeing them fighting before the fatal plunge. But the judge ruled that prosecutors had not proven the charge beyond a reasonable doubt.
