Let's face the facts, this show depended on audience to survive. He couldnt know how long it would take.
Probably Partridge was the choice when it started, but after so many years, and having forensics guys Being the
serial killer in other shows, so he decided the new RJ two years ago. (No way he started the show without one RJ).

He had to move on, otherwise could lose audience, he said it was An audience demand.
But the thing is, if Sherrif was RJ, any one on the show could be. I enjoyed reading and writting theories, but RJ wasnt even decided, so the fans with they most popular suspects got some influence in Bruno Heller decisison.
