Boden killed four women, three in Montreal and one in Calgary, earning the nickname The Vampire Rapist for biting the breasts of his victims, and received four life sentences.
An autopsy conducted by Dr. Jean-Paul Valcourt found two small fibers under the fingernails of her left hand, indicating that – contrary to prior belief – that Way had indeed struggled against Boden.
In their investigation of the murder, the police were able to find out from two of her colleagues that she was seen at a stoplight riding in a blue Mercedes-Benz on the night she died; the car was reported as having a distinctive advertising bull-shaped decal in the rear window.
A friend of the victim also informed police that she had been recently dating a man named "Bill", described as a "flashy" dresser with neat, short hair.
The police in Calgary were in possession of a copy of the photograph recovered from Archambaut's apartment and, as Boden resembled the man in the picture, they held him for suspicion in murdering Porteous.
As there was nothing in Canadian literature on forensic odontology at the time, Swann wrote to the Federal Bureau of Investigation (FBI) in the United States, hoping for any information on the matter.
Swann received a reply from FBI Director J. Edgar Hoover, who directed him to England, where he met a man who had dealt with 20 or 30 cases regarding bite marks.
The evidence provided by Gordon Swann was sufficient for the jury of Boden's trial to find him guilty for the murder of Elizabeth Porteous and subsequently sentenced to life imprisonment.
Boden then returned to Montreal to face trial, where he confessed to three murders of Shirley Audette, Marielle Archambault, and Jean Way, and was sentenced to three additional life terms.
In 1977, Boden was granted a credit card by American Express five years into his life sentence, which he used while out on a day pass from prison in Laval while eating lunch with his social worker in the Kon Tiki restaurant at the Mount Royal Hotel in downtown Montreal.
