Amateur sleuths please weigh in. These are some head scratchers that get me thinkin'. 1 18 1 Jack the Ripper Thought this one was solved, but since numerous people have come to different conclusions I'll consider it unsolved. 2 13 2 In Search of D.B. Cooper I find this case fascinating. 3 15 4 Escape from Alcatraz Check the movie out too, but this is one great mystery 4 15 5 Zodiac Wow, perhaps the granddaddy of em' all. Websites, movies, books, crazy people ranting in the street. Everyone has a theory what is yours? 5 12 3 Roswell I am aware the military said it was a 'weather ballon'. C'mon. 6 9 3 Georgia Guidestones Any idea who built this, and what their purpose was? 7 5 7 Perfect Murder, Perfect Town This story broke my heart when I heard it. Honestly, it still does.
