Elizabeth Anne Porteous, a dedicated 33-year-old high school teacher, was a woman with a life full of purpose and promise. Her commitment to her students and her profession was a defining aspect of her character. But on the morning of May 18, 1971, her familiar routine was broken when she failed to arrive for work in Calgary, Alberta. The absence of the dependable teacher was alarming enough that the manager of her apartment building was contacted.
A check on her welfare led to a devastating discovery that would send shockwaves far beyond her quiet community.
Inside her apartment, Elizabeth was found on her bedroom floor. She had been raped and strangled. The scene showed clear signs of a violent struggle, a testament to her fight against her attacker. In the disarray, investigators recovered a small but crucial piece of evidence from beneath her body: a broken cufflink. Her death was not only a personal tragedy for those who knew and loved her, but it would also become the final, horrifying chapter in a string of brutal murders that had terrorized another Canadian city over 2,500 miles away.
The investigation into Elizabeth’s murder quickly drew connections to a series of unsolved killings in Montreal. Between 1969 and 1970, three young women—Shirley Audette, Marielle Archambault, and Jean Way—had been murdered in a terrifyingly similar fashion. All had been sexually assaulted, strangled, and bore the chilling signature of their killer: savage bite marks on their breasts. The perpetrator, known only to the public as "Strangler Bill" or "The Vampire Rapist," had vanished from Montreal, leaving a city gripped by fear. Now, it was clear he had resurfaced in Calgary.
The man Elizabeth had recently been dating was known to her friends as "Bill." This detail, combined with the method of her murder, provided a direct link to the Montreal cases. The day after Elizabeth's body was found, patrol officers spotted a distinctive blue Mercedes parked near her apartment, a car that witnesses had seen Elizabeth in on the night she died. The car belonged to Wayne Clifford Boden, a former fashion model who had moved from Montreal a year earlier. When police arrested him, they had more than just suspicion.
During questioning, Boden admitted to dating Elizabeth and being with her on the night she was killed, though he claimed she was alive and well when he left. He also identified the broken cufflink found at the scene as his own. The most damning evidence, however, came from the bite marks left on Elizabeth's body. In a landmark case for forensic science in North America, a local orthodontist named Gordon Swann was called in. By creating a cast of Boden's teeth, Dr. Swann was able to demonstrate 29 distinct points of similarity between Boden's dentition and the marks left on Elizabeth.
This pioneering use of forensic odontology was the key that unlocked the case. The evidence was overwhelming, and a jury found Wayne Clifford Boden guilty of the non-capital murder of Elizabeth Anne Porteous. He was sentenced to life in prison. The investigation into Elizabeth's death had not only solved her murder but had also unmasked the man responsible for a reign of terror that had haunted two cities.
Following his conviction in Calgary, Boden was returned to Montreal, where he confessed to the murders of Shirley Audette, Marielle Archambault, and Jean Way. He received three additional life sentences for those crimes, ensuring he would never again be free. Boden died of skin cancer in prison on March 27, 2006. While his capture and conviction brought a measure of justice, it came at the immense cost of four innocent lives. Elizabeth Anne Porteous, a beloved teacher whose final moments were a fight for her life, is remembered not only as a victim, but as the woman whose murder directly led to the end of a serial killer's brutal spree.
