MIAMI (AP) - A jailhouse informant says she was abused by fellow inmates and corrections officers after reporting that a missing Florida foster child's caretaker had confessed to the murder.
    
Robin Lunceford testified Thursday one officer hit her in the head with a radio and another caused her to fall by stepping on her shackles. Lunceford says she suffered similar abuse by inmates who accused her of snitching.
    
Lunceford says 66-year-old Geralyn Graham told her while both were in jail that she smothered 4-year-old Rilya Wilson girl with a pillow because Rilya was evil and mentally troubled.
    
Graham faces life in prison if convicted of killing Rilya, whose body has never been found. Graham claims a state welfare worker took the girl and never returned her. Police say that is false.
