9. Its has been 68 years since the body of 22-year-old aspiring actress, Elizabeth Short, was found. Elizabeth was found gruesomely murdered, cut in half and left at the vacant lot in Los Angeles. This murder has become one of the most enduring unsolved crimes ever, since her murderer was never discovered. Black Dahlia, as she was called, was found with her mouth slashed ear-to-ear, her hair and body thoroughly washed and her upper and lower halves carefully posed so they looked like a broken mannequin. The case was never solved, and in 2006, Brian De Palma directed a movie about the tragic death of young Elizabeth Short in 1947.
