When Dexter, Rita, Debra (Dexter's adopted sister) and "Rudy" came to sort out Joe's house, Dexter took blood samples of himself and Joe and sent them to Vince Masuka to perform a DNA test, which came back as a match. Dexter suspected that Joe's apparent heart attack was actually murder. However, the body was cremated before Dexter could obtain proof, and thus he never found out what "Rudy" had done. Rudy and Dexter stole Joe's ashes and scattered them at the entrance of Joe's favorite bowling alley.
