I don't know if I'd neccessarily blame it on a rock climber. Many of us have been the victims of quickdraw theft at the Creek. As I recall, many of the draws were removed with the assistance of a large branch(ie set the branch against the wall and climb up it). Obviously, only the first few draws were stolen. A similar means could have been used in this case (by one of those non-climber types), as it was only the first bolt.
