I have thought on this a great deal. My conclusion; the search dogs turned them on to him. I found one tidbit (and photo!) at Primenews.com about giving the dogs his shoes to sniff and taking them back to the VD's, later they came and took the closet doors.
I wonder if the dogs on Saturday had shown interest in where the Motorhome had parked, but there was nothing the cops could do until he came back. For sure, it seems they were focusing on him from very early on.
Some have commented on him leaving so late on Saturday morning, but I thought he left at Sunrise. Does anyone else have a good article reporting the actual time he left?
It could have just been the result of good basic police work,too. They asked the VD's who they had made contact with that day,if any of them acted strange,etc,etc,etc. His name was on the list,and it may have rung a bell none of us know about yet for fear of "poisoning the jury pool". Chances are this guy had been arrested for crimes involving children in the past,but the charges were dropped.
