In June 1974, 17-year-old Catherine Sjoberg was enjoying all the festivities of prom night when a heated argument with her boyfriend at the post-prom dance sent her storming off into the cool summer night, never to be seen or heard from again. For nearly 50 years, law enforcement in Jefferson County, Wisconsin, have been haunted by Cathy’s disappearance as they’ve tried to find answers to the nagging question still weighing on the community today: how does someone vanish into thin air?
Cathy was last seen in a long, light blue formal gown. She had long, light brown hair parted in the middle and green eyes. She was about 5’4” or 5’5”. Cathy would be 65 years old today.
