Child's remains found near home of Caylee's grandparents

ORLANDO, Florida (CNN) -- Remains described as being those of a small child were found Thursday near the home of missing toddler Caylee Anthony's grandparents, a spokesman for the Orange County, Florida, sheriff's office told CNN.

The discovery was made about 9:30 a.m. by a utility worker who alerted authorities, spokesman Jim Solomons said. Investigators, including those from the Anthony case, were on the scene, he said.

Caylee Anthony, 3, has been missing since June. Her 22-year-old mother, Casey Anthony, was arrested last month and faces charges including first-degree murder in the girl's disappearance.

CNN affiliate WFTV reported that the utility worker, a meter reader, picked up a bag at the site and a skull fell out.

Solomons said he could not confirm reports that the body was that of a small girl.

Asked the distance from the site to Casey Anthony's parents' home, he said it would be "very safe to say it's in very close proximity.
