Canada's Serial Killer Nurse Tells All "I had been killing people using an insulin overdose, okay." That's what registered nurse Elizabeth Wettlaufer told her friends, her pastor, and her doctors. On October 5, 2016, in Woodstock, Ontario, she told the police all about it. World War II veteran James Silcox was "the first one to die as a result of what I did." After killing him with an insulin overdose, the nurse went home and played computer games. "The doctor wants you to have your vitamin shot," the nurse told Maurice Granat before administering the insulin overdose that killed him. After giving Helen Matheson her blueberry pie, nurse Wettlaufer overdosed the woman. "After I did it, I got that laughter," she told police, and she laughed when Helen died. Nurse Wettlaufer told Mary Zurawinski the injection was "for pain" but it killed her as intended. And after getting the news, nurse Wettlaufer departed on a Caribbean cruise. As the nurse told police, Gladys Millard took longer to die than some others. "Take your medicine," the registered nurse told Arpad Horvath as she injected the insulin overdose that killed him. Nurse Wettlaufer also told police she killed Maureen Pickering and Helen Young. She told police how, when and why she killed her victims. The nurse told police she attempted to kill at least four others, and that she never "got caught." What would be the serial killer's penalty for inflicting so much death and suffering?
