I think I'm seeing something telling in these text messages...planning between SS and DM. That whole FRAMING ASPECT DP didn't want to get into and the OTHERS INVOLVED hahaha. SS is heading in the direction that DM bought the truck from someone in Kitchener. The person who DM bought TB's truck from is the "actual" murderer

and DM was just an innocent dupe looking for a diesel truck to buy AND coincidentally found TB's truck in Kitchener. After DM bought TB's truck, SS filled DM in on how he was now in possession of a stolen truck and the owner was murdered. Now in those texts SS is suggesting DM goes to the cops. DM is feeling so awful for the Bosma family now realizing this truck sitting in his hangar is stolen and the owner was murdered by someone else.
IMO it was all scripted and planned, those text messages to make it appear as DM now had a "warm" (hot as in stolen) truck on his hands. But of so coincidentally DM was on line looking at TB's truck. SS better be careful or else he's going to find himself perjuring himself and it ain't going to look pretty. He could end up finding himself behind bars also. Who knows, that might just happen anyhow after all is said and done. He may be facing charges we are not privy to because of the PB. IMO SS knew DM was up to no good and was planning on stealing a truck. There's a good reason why AJ and SS are no longer talking. AJ sees right through his SIL. ALL MOO.
