This story is old. Who cares?
Her mom did! no one else
her MOTHER
I remember when all of this started, rumors say he Mom killed her by accident or something like that to go party? According to wikipedia, they say this:
Her then 22-year-old mother, Casey Marie Anthony, was tried for the first degree murder of Caylee but acquitted. She was, however, convicted of misdemeanor counts of providing false information to police officers.
