Casey Anthony broke her silence for the first time since she was acquitted for the death of her two-year-old daughter, Caylee. This marked the first time Anthony ever spoke of her daughter, nine years after her death. Anthony was acquitted of murder, but was convicted for lying to police about Caylee's whereabouts. Anthony still says she doesn't know how her daughter died, although the judge on the case believes she killed her daughter by accident and covered it up. "People lie to the cops every day, cops lie to people every day. I'm OK with myself. I sleep pretty good at night," she told the Associated Press.
