Wayne Clifford Boden (1948 – March 27, 2006) was a Canadian serial killer and rapist known as “The Vampire Rapist.” Between 1969 and 1971, he murdered four women—three in Montreal and one in Calgary—biting the breasts of most victims, a macabre behavior that earned his infamous nickname. Boden was arrested in Calgary on May 19, 1971, after investigators tracked a blue Mercedes linked to his last victim, Elizabeth Anne Porteous. In a pioneering forensic odontology case, bite-mark analysis by orthodontist Gordon Swann matched at least 29 points between Boden’s dentition and the wounds, making it the first North American murder conviction based on dental evidence. He received four concurrent life sentences (four murders) and began serving them on February 16, 1972, in Kingston Penitentiary; later earned notoriety when he somehow obtained an American Express card during a day pass in 1977 and briefly escaped before being recaptured. Boden died behind bars from skin cancer at Kingston hospital on March 27, 2006, after a six‑week hospitalization.
