Just before Christmas 1987, a young woman left 'Baby Mary' in a Calgary parking lot and walked away. Thirty years later, the same events played out in the same city. In this episode of This Is Why, we ask why someone would abandon a baby and whether an abandoned baby would want to be reunited with their birth parents.
