It seems like whoever the other 21 potentially viable prints were from, doesn't really matter, imho. The Crown seems to have overwhelming circumstantial and direct evidence to suggest that DM and MS were together and with TB and his truck on that fateful night. Other prints could have belonged to Tom, Dick, Larry, Harry and Mo, but since they didn't own the incinerator where TB's blood was reportedly found, along with what appeared to be an entire set of incinerated human bones still in the bottom, and TB's truck wasn't found at one of *their* houses, and there doesn't seem to be video of them driving to one of *their* properties in TB's truck only hours after he was last seen, and etc etc etc etc etc etc, is it even important who the other prints belonged to?
For me, it would be interesting to know, but if the prints were put through some kind of electronic system that didn't find matches to other than TB, should they spend time and resources on trying to figure it out? And if so, for what reason? DM's prints have absolutely no reason for being anywhere near TB's truck, unless he was there that night. They did not know of one another before this truck buying escapade. TB's blood has absolutely no reason for being on DM's incinerator found on his Ayr property.
The defense may be trying to confuse what is important with meaningless sidesteps for obvious reasons, but in the end, I'll love to hear the explanation for how DM's prints flew onto TB's truck, and how TB's truck ended up in DM's trailer on DM's mother's property, and how TB's blood ended up on DM's incinerator. If they can come up with viable answers to those things, then the other 21 potentially viable prints might need to be more closely investigated. MOO
