I just keep thinking that if there was not a car, have the police considered a hidden cellar.
Perhaps nearby or even within surrounding properties?
Look at this:

I read a story that made me think of this case.

I know that LE was allowed to search buildings on a property near where the abduction took place, and this seemed to be no problem for the person who allowed it, but could there have been something hidden there or nearby?
It gives me the creeps to even imagine it, but I can't get over the fact that no vehicle was seen or heard after Jacob was taken. The other boys were told not to look back, what was it they were not supposed to see? Could it have been right there, nearby?
I don't know if this sort of scenario has been discussed already, just wanted to put it out there.
