Casey Anthony is opening up in her first sitdown interview. She became the "Most Hated Mom in America" during her trial for the murder of her 3yearold daughter Caylee. Now in a threepart documentary, Anthony says "The only person who matters to me still is my daughter and I am still defending the fact that I did not hurt her." She blames her father, George Anthony, for the death of her daughter. She’s also accused her father of sexually assaulting her, which he denies.
