What is baffling to me is how would the perp/s know that William and his sister would be at that house without the mother, grandma or the dad supervising the children around that yard if they were outside playing? Or what if dad decided to take the kids to town with him to give his wife a break, or they decided to do other fun things away from the house. Who would know their every move unless they were being carefully watched for that particular moment when everything fell into place for them to grab William? And did they ever think that grandma's house could of even had surveillance cameras as lots of people do nowadays with home break ins. I think whoever took William knew things no one else would have known, and i think it was someone that knew grandma, or knew about the families movements that day, as another poster said perhaps they were followed to their destination from the city. It is true with a lot of these missing child cases that it is someone the family knows, or who they have been familiar with before.
