Orange County Sheriff's officials say they believe he was in the area on Dec. 11 following up on his own lead when he discovered the bones and skull.

Capt. Angelo Nieves said police questioned the worker again, as well as the sheriff's deputy who took the original call. They want to know more about what prompted him to contact authorities and how they handled the tips.

The meter reader first called on Aug. 11 to report a bag by the side of the road, MyFOXOrlando.com reported. A deputy wasn't able to locate Kronk.

On Aug. 12, the meter reader called a crime hotline. The information was passed on to the Orange County Sheriff's criminal investigation division.

And on Aug. 13, the utility worker called cops a third time, MyFOXOrlando.com reported. He met with police, and a deputy went into the wooded area to investigate the Kronk's claims, but didn't find anything, the station said. The scene was then cleared as a possible place of interest in the case.

There is now an internal probe under way within the police department into how the matter was handled.

"There are a lot of questions about the thoroughness of that response," Nieves told MyFOXOrlando.com.

Investigators were at the wooded crime scene all week in an exhaustive dig for evidence. They said late Thursday they found additional bones that also appear to be from a child.
