A kind member linked a very detailed article why infrared would not have captured the children. In further reading, the kids were off on the Wednesday (Truth and Reconciliation/national holiday) and apparently the mom called Lilly in sick because of a cough. (Only mention of Lilly, not Jack.) I did read an earlier report that said Jack was enrolled in pre-primary (which is jr. Kindergarten in i.e., Ontario). So the parents elected to keep both children home from school, which I would have, too.I am thinking that you might be on to something here, timing-wise. I just cannot understand why neither the infrared, nor the dogs picked up anything. And absolutely no artifacts belonging to these two children has been found, near or far. They could have been abducted, but that is less likely than it might seem, given the remoteness of the area.
