Susan Rancourt disappeared on April 17, 1974. She was last seen on a college campus where she attended school. It is believed that she attempted to help a man load heavy books into his car. The man was wearing a sling. Susan Rancourt would normally be a victim of medium risk; a student walking on campus with a certain destination in mind. However, the dynamics of her situation changed quickly, unbeknownst to her, when she walked upon a stranger whom she chose to help. She immediately became a victim of opportunity.
