I have no idea what's going on in this hand, to be honest.

So . . . most likely BB checked the flop either because he missed (or mostly did) or because he flopped an absolute monster. Once he checkraises, well, the monster is something to worry about. That said, you do have trips, and I'm not ready to assume BB has QQ. In any event, if BB is thinking about protecting his hand, then his checkraise could show weakness, like Shill mentions.

When BB finally slows down again when you raise the turn, I start getting optimistic. The amount of action he's been willing to put in so far concerns me a bit, though. I'm hoping he has AA or KK or something and doesn't know he's in trouble.

I'd think about raising the river, but like I said, I don't really know what's going on. So I can see just calling. If BB's goal was to take a very confusing line, then it worked on me.
