Again I ask-where do you start? What area would be beginning of the search? Or the end even?
Or do you call for an all-out search by hundreds of volunteers in a specific mile radius? If so-where?
I would start with some good old fashioned local knowledge and some basic common sense. Roll out the topo map and ID some high probability locations based on that local input. Keeping in mind, a silver mini-van is not an all terrain off road vehicle. Where ya gonna go with a mini-van in the middle of the night ? Your in a hurry and under a lot of stress, think straight lines radiating out from the Exxon station. We do know the van was seen on video traveling North bound. This is where the profilers can provide statistical parameters in terms of probable distance driven from an abduction site to the site of the crime/dump site. They might also be able to steer the search toward water or not.
Mona lake was the first point of interest on the map that caught my attention on day one of this case. Maybe a search party can take a look there and we can X that off the map as searched and cleared ?
