Nancy Grace is livid at Casey Anthony -- slamming her new legal advocate gig as a shameless cash grab and insisting the focus should remain on her murdered daughter, Caylee.

In October 2008, Casey Anthony was indicted on first-degree murder charges in connection with her daughter’s death, though the toddler’s body hadn’t been found. Two months later, in December of 2008, a meter reader found Caylee’s skeletal remains less than a mile from Casey’s parents house.
