A few minutes before 9 PM on December 20 1983, 22-year-old Erin Gilmour finished her tasks for the evening at the boutique where she was working in the Toronto shopping district of Yorkville and then closed up shop. Though the details about what happened next are murky, one thing is clear: someone made their way inside the boutique, then attacked her, raped her, and stabbed her repeatedly. Around 9:20 PM, Gilmour’s boyfriend found her in the apartment above the boutique where she lived. She was tied up and bleeding profusely in her bed. By the time he called Toronto police, she was already dead.
