The bones of a small child were located Thursday in woods less than a half-mile from the Orlando home of a 3-year-old girl who has been missing, but officials were not able to say whether they were the remains of the toddler.

A utility worker stumbled on the skeleton in the outlying middle-class suburb around 9:30 a.m., Orange County Sheriff’s spokesman Jim Solomons said. There was nothing that automatically indicated the body was that of Caylee Anthony, he said.

Caylee’s mother, 22-year-old Casey Anthony, maintains that she left the child with a baby sitter in June, however she didn’t report her missing until a month later. Anthony has been charged with first-degree murder in connection with her daughter’s death.

Orange County Sheriff’s spokesman Angelo Nieves said authorities informed Caylee’s grandparents about the discovery, but refused to discuss whether the remains were Caylee’s.

In a statement Nieves said, “It would be premature to speculate. We’re not going to release any more information at this time. We don’t want to compromise the investigation.”

The FBI and forensic investigators were working at the scene, which is located on the outskirts of the Anthonys’ neighborhood about 10 miles southeast of downtown Orlando.
