With the evidence so far, I find Dellen with no doubt in my mind Guilty of 1st degree. I'm kind of still on the fence for Mark but finding him guilty as well. Reason, they both knew they were going to steal a truck and both guilty of "while committing or attempting to commit kidnapping and forcible confinement" and "while committing intimidation (even if it was brief)" as per Canadian first degree murder charges list. We are seeing evidence that lead us to believe this was planned and not an accidental slip of the trigger and both tried to cover the murder. I really don't think this crime could have been pulled off by just one person! I believe more evidence is to come as I don't believe forensic is done and we will see a bigger picture painted. The Crown is strategically laying their cards just right and at the right moments. Forensic has put cards on the table but IMO haven't reviled them all yet.
I believe DM pulled the trigger but for those two reasons above, I find MS guilty as well. I have flipped back and forth on MS but those words "gone..gone..gone" stick in my mind (sounds like a proud gangstas words) Even if he was intimidated by DM or DM made threats on M's life (if he talked) he had ALOT of opportunity to go to the cops....DM would have been in custody and MS wouldn't have need to fear his life. He chose not to which makes him look guilty as hell! His actions after the murder speaks volumes of him as well.
