I wonder if the dogs found any scent of Kyron at all. Wouldn't they have followed a scent trail if he walked anywhere out to the parking lot? If the dogs found nothing outside the school of Kyron, then he must have been murdered or drugged unconscious inside the school and put into some sort of container, then removed from the school whenever, could have been at any time from 8:45 to 3:30. There were a lot of parents removing projects that day to their cars. There also would have been your normal delivery/pick up people. There was mowing going on of the field, was there other landscaping going on that day? What do they do with their clippings? I wish I knew whether or not the dogs found ANYTHING at all.
BillyLee,
IIRC, scenthounds were taken into Skyline,but they did not get any "hits" at all... I seem to remember that it was a while afyter Kyron disappeared ( not the next day,for example). If the floors,say,had been mopped with disinfectant it could well have thrown the dogs off... I do not know if cadaver dogs were ever used,either in the school,outside the school,or in the Horman's home...
ETA :
The fact that the dogs got no "hits" at all inside the school made me wonder if Kyron was ever in the school...that was about the end of the first week after he disappeared. Of course he was there,though...
