Planted evidence
Police believed that Pam used Gumpenberger to frame Russell for the murder of his wife, Betsy. They also believed that the $900 and a handwritten note found in his pockets at the time of his death were planted by Pam. The handwritten note was carefully written in such a way to make anyone who found it believe that it was an instruction for him to take “Russ’ money” and then kill Pam.
