unsolved mysteries

One example of unsolved mysteries is the mystery of the Bermuda triangle. It is a triangle in the Atlantic Ocean where many boats and planes have mysteriously disappeared. This is an interesting case because there are a lot of theories to how they disappeared. They range from aliens to electrical storms. Another unsolved mystery is the mystery of the black dahlia. A girl in the late 40's was brutally murdered and her body was severed in two. The murderer was never found even though there was a massive investigation.
