Has it been chronicled here what vehicles contributed to the tire tracks on the Rassier driveway? Here's a shot from DR that was provided for Joy's blog. Remember, these photo's are lit and it would have been near pitch black out in late October. Couple that with the fact that the line of site from the Rassier farm to 91st Ave is near nil and I find it next to impossible that DR could have noticed these boys riding by on their bikes. Yes they had a flashlight, but based on the photo it would have been near impossible to have seen it from the Rassier household.
First, he would have had no idea where they were going and when they would be returning. For all the perp knew they were just riding up and down the road. Second, he would have had to have been walking around down by the end of his driveway WITH A GUN IN HAND and a large chest that could hold an adolescent boy (according to some speculators). After procuring Jacob, he would have had to hurry him back up to the farm, or rent a spaceship and fly him there from Jacob's last footprint, all the while leaving ZERO evidence behind. DR than would have to find an elusive hiding place, all under the premise that LE could/should be knocking on his door any moment after the abduction.
Once they would have made contact with DR, he would have had to been completely open with showing them every crevice of the property for fear of letting it slip that Jacob was being hid somewhere.
Finally, according to some speculating here, DR packed Jacob into an instrument case and drove him right under the cops noses the day after the most highly profiled abduction in the history of Minnesota. How would he have known that LE wouldn't have stopped him and asked to search his vehicle?
The only reason there is speculation that DR committed this crime is due to the lousy police work. If they would have checked the farm, checked his vehicle and not polluted the crime scene he would never even have been considered a POI (IMO).
All facts of this case lead to Jacob having been taken away in a vehicle. My opinion is that LE did not account for all vehicles that traveled on the Rassier driveway. It very well could have been that multiple vehicles with the same tire tread passed along the Rassier driveway that day.
Also in the picture note the field road. Had that road been thoroughly examined for vehicle prints? I can't for the life of me figure out how the perp marched Jacob down that driveway but left ZERO evidence of following him.
