Associated Press WriterORLANDO, Fla. (AP) -- A Florida sheriff says the child's skull found near the Orlando home of a missing 3-year-old girl was "totally underwater" during previous searches for the toddler.
Orange County Sheriff Kevin Beary said Thursday investigators could not immediately say whether the remains belong to Caylee Anthony.
Beary says officials searched the surrounding neighborhood several times since she went missing in June. A utility worker found the remains Thursday morning.
Beary says FBI and forensic investigators will work through the weekend to identify the remains in what they consider a top-priority case.
Caylee's mother, 22-year-old Casey Anthony, has been charged with first-degree murder in connection with her daughter's death.
