In the summer of 1991, Calgary, Alberta became a hunting ground. Between June and October of that year, three young women vanished from the city's streets—and all three would be found dead in remote locations outside the city limits. This week we dive into the cases for Jennifer Joyce and Shawna Van Der Basch.
