A Florida grand jury has indicted the mother of a missing 3-year-old girl on first-degree murder and other charges.
Prosecutors say Casey Anthony was indicted Tuesday and arrested on charges that she killed her daughter Caylee. Investigators had previously questioned why the 22-year-old mom didn't contact authorities for a month after her daughter's June disappearance.
Anthony had previously been charged with child neglect, lying to investigators and some unrelated fraud and theft counts.
A 19-member grand jury returned the indictment following testimony Tuesday from Casey Anthony's father, a detective, a cadaver dog handler and an FBI agent.
