He did not go back to the area three days in a row. On the 11th he was there because it was on his meter reading route at the time.
On the 12th he called at about 9:00 p.m., he was not calling from the scene.
On the 13th he called from the scene at about 3:14 pm because he had been asked to go to the scene, let the LE know when he was there, and to meet with them.
That is NOT going to the scene 3 days in a row.
After that time, he apparently covered another route until December 11th when he was back to reading meters in that neighborhood.
The only thing that is missing is that all the calls that have been released, have been edited, and we are not hearing the full calls.
There is another call, I am not sure people know about and it is the call that Kronk actually made on the 13th to his dispatcher. It too has been edited. It can be heard here.
LISTEN: Calls between the utility worker who found Caylee's remains and his dispatcher
One section of dispatch call (that would be heard at the 38 second mark) has been omitted per the Orange County Sheriff's Office, Sgt. John Allen, as this is part of an active homicide investigation.
