Dr. Mario Corelli
Talbot Huddleston, a “john” of prostitute Karen Wolek, murdered Mario—thinking that he was his identical twin brother Marco Dane, who had been blackmailing Karen. With a growing list of enemies about town, Marco allowed everyone to believe that he had been murdered, and in the meantime took on his slain brothers identity.
Viki Lord Riley (Marco’s biggest nemesis) was arrested and sent to trial for Marco’s murder in early 1979, but was later exonerated. A year later, “Mario” was revealed to be Marco, who was then arrested. (Not sure if Talbot was ever brought to justice.)
