it looks as if it never got off the ground. I did some internet research. It looks as though William link was going to write it for Broadway back in 2007, however I don't think it ever made it onto Broadway. Leading role was going to be given to an actor named Boucher. I for one have never heard of that person. They never selected a murderer.

If anyone else has more up-to-date information I would love to read about it.

Plenty of info, e.g.
