Associated Press WriterORLANDO, Fla. (AP) -- Authorities say they are seeking a search warrant for the Orlando home of a missing 3-year-old girl after a small child's remains were found nearby.
Orange County sheriff's spokesman Carlos Padilla said Thursday that investigators cordoned off the home belonging to the grandparents of Caylee Anthony, who often stayed at the home with her mother.
Caylee's mother, 22-year-old Casey Anthony, insists that she left the girl with a baby sitter in June, but she didn't report her missing until July. The mother has been charged with first-degree murder.
On Thursday, a utility worker stumbled upon remains of a small child less than a half-mile from where the girl lived.
Investigators were trying to identify the remains. The medical examiner left with the remains about 3 p.m.
