Quick update: a friend of mine talked to a guy who knows the guy who stole it, and actually this guy (the guy who knows the guy who stole it) had seen it the night before in a storage room at an apartment complex on the island called Shorewood. So we went there and looked: it was gone.
At this point we all pretty much know who it was, we just need proof. And we have to keep pressure on him to give it back, no questions asked :| it's like it's turning into a game for this group of people involved. The people involved and the people who seem to be...passing it around? The stoners. They're giving themselves a bad reputation, even worse then before. It's too bad, because I've definitely never done anything to mess with them.
Anyway, if I don't get it back by the end of the week, it's very very unlikely I'll get it back at all.
