No...not the dwarf. He was there at the end. The viewer was left with the impression that he was upset at the girl going with the handsome guy. He climbed the rope ladder and jumped to his death, or so you were led to believe. But right away when you saw the casket, you saw that it was a large casket--not a small one. So that was Clue #1 that it wasn't the dwarf who died. Clue #2 was that the dwarf was right there throwing the ring into the hole with the casket. So, the girl had to be in the casket (why throw a diamond ring onto a casket containing the guy that took your girl?).
But if we agree that it is the girl in the casket, how did she die? I say it was the guy she was shacking up with. He probably got jealous of the dwarf (why, I wouldn't know). But you don't see him at the burial site.
I think Edge and Adam have him locked up in the tiger's cage
