Scott Pilgrim : Murderer ?

Most of us are familiar with Scott Pilgrim and his epic adventures, how he won the love of Ramona Flowers and defeat the League of Evil Exes. But I wondered, what happened to the exes, we see them turned into coins. But are they dead? If so , why isn't he wanted for murder? There were plenty of witnesses to him "defeating" them. Is no one curious what happened to a famous actor, rock star, or mogul? I'd like your thoughts on this.
