You're probably right,
@MassGuy. I guess I'm still in the premeditated camp, as well as some shady business dealings going on behind SM's back, so I figure maybe BM thought he was covering his tracks by using the DW. I'm just trying to come up with a few different ideas for why it was even mentioned on PE. I feel certain they introduce all of these little clues in their videos bc they have more insight in to this case than the average Joe, but maybe they don't? I believe they have a little more info than we do though, and they blast out these little nuggets of incriminating info to really make BM and his cohorts squirm with anxiety. Could just be wishful thinking on my part though.
IMO.
