Who Done It?

Above: Michael Moran, Butch Maxwell, Vera Barton-Caro, Frank Wilson and Arlene Merryman.

What actor has most often been the killer? We decided to do the math. Below are the official tallies, as of November 16, 2007
Counting each original run only, not reprises.
Credits for murderers (and victims) are based on actors who created or were considered "principles" for characters, not understudies.
These are the actors listed first on the show pages and the "Mystery History" archives page.
