Why would he be disconcerted someone was able to give a description of him, when he didn't even bother to disguise himself with a hoodie or a hat? He must have expected that there would have been a description of him.
A lot of country roads are paved now, and many of the paved ones are secluded, especially late at night, which would be when they were there, in my opinion. And they have many acres to drive back into, they didn't have to stay close to the road. I bet if you spent a night out on that road, you could count the vehicles that passed all night on your fingers. How many people pass by MB's house on any given night? I bet more than on that farm road.
Lets pretend for a moment that DM did steal the Harley in the trailer, or even knew about its theft. It was stolen in broad daylight on a busy residential street, why on earth would they then feel that leaving the truck in a trailer ready to tow on a residential street would be safer than in a secluded section of farmland? That's pretty ridiculous in my opinion. Also, anyone who has ever lived in the country and had friends in the OPP will tell you that in small rural towns, when there is a crime like car theft committed, the cops always pretty much know right away who the suspects are and where the property is going to be found. Small communities like that have a much lower car theft rate, that is one of the reasons why auto insurance is so much cheaper in the country. The idea that they might have thought it more likely that a thief would find it and steal it out of a rural field than a residential neighbourhood is pretty far fetched. And even if someone did steal it, and then got it home and found out that it was the TB truck, do you think that they would then call the cops now that their finger prints are on it, and tell them that they accidentally stole a stolen truck? It actually would have been a bonus for the original thieves, so that theory doesn't seem to hold water for me.
And the trailer may be larger than a burnt body, but if you have ever spent any time on any deep country roads, you will see plenty of vacant land and farm land and wooded areas with random trailers of all types, vehicles in all types of conditions and machinery that makes you wonder what it is. Often those things look like they have been there for years, and no one thinks twice about them, and most of them never get stolen, apparently. Again, I don't see them thinking it would be stolen from or even noticed at the farm was a realistic motivation for moving the truck. So what if a couple of neighbours might have seen a trailer at a farm, when countless neighbours were certain to see the trailer at MB's. I bet the neighbours had even seen trailers there before, like when some of the digging equipment was brought in, I doubt that they would have broken the lock to look inside.
In my opinion, the seat would have been one of the first things to be removed from a bike being chopped for parts. From what I recall, the bike was stolen 6 months before he was arrested, if it hadn't been sold it was likely because they discovered one of the many hidden vins that the owner had placed in it and whoever stole it could no longer trust that it didn't have others and they would have to now inspect every single part for a hidden vin, not worth their time. But regardless of that, if they knew that there could be hidden vins on it, they knew it could be identifiable and therefore having it around in the hanger if they thought it might be searched is ridiculous. It was in a trailer, how hard would it be to move one more trailer? And I believe the articles about the chop shop said that there were numerous parts with the vins illegally ground off, they would have known that those were illegal to have and could have easily moved them if they felt that the hanger was possibly going to be searched, that is only logical.
If we are to believe that he thought the truck was safe at his mother's because it wasn't his property, then we must assume that he thought that his properties might be searched, and therefore he would not have left a body and stolen vehicles or their parts at any of his locations, he would have brought them all to his various family member's homes. It could be that his mother had more than one property, why didn't he move the rest of the evidence to those places if he felt that they were safer than his own? I'm sorry, but it still does not make sense to me.
