Two of the most chilling unsolved cases in American history. In 1947, Elizabeth Short—later dubbed The Black Dahlia—was found brutally murdered in Los Angeles. Her body was sliced in half, drained of blood, and eerily posed. Her face was carved into a grotesque smile. Despite endless theories and suspects, no one was ever charged. The case remains open, and her killer still walks free… if he’s even still alive. Decades later, Natalee Holloway vanished during a high school trip to Aruba in 2005.
