Hi everyone.
The items he never separated himself from were in the truck. If he was napping in there I doubt he would have been able to open the door by himself. If he was able to, I would think he would have called out if he didn't see his parents or great grandfather. Was the truck door open or closed when he was discovered missing? If his parents opened the door for him upon arrival, one would think he would have grabbed his blanket and other items. If he was napping and was able to open the door, I don't think he would have closed it after getting out. If he was in the truck and abducted, an abductor would not have closed the door after removing him from the truck lest someone hear the door close. I also don't think an abductor would just lie in wait and hope for the chance to abduct a child with not knowing if a child would ever arrive. If he was outside the truck without his belongings, I would think that a wild animal grabbing him would have caused some sort of confusion with him yelling out in horror or pain.
I recently saw a TV show where a professional tracker was brought in. He was amazing and 100% spot-on. It was amazing in that he was able to track footprints on gravel and over stones. Sadly, scene would be highly compromised by now.
None of this makes any sense and it's driving me nuts.
