If you have a chance to watch or record Diagnosis Murder starting at 11 AM ET/PT today (7/13) on Me-TV, Staci Keanan plays the daughter of a character played by Patrick Duffy who collaborates with her new husband on their wedding day to murder her dad and blame it on her stepmom. This was originally aired fall 1998 not long after Step by Step left the air. Who knew Dana hated her stepdad that much? ;)
