Two Unsolved Mysteries

my two examples of unsolved mysteries are:

The Zodiac killer-
I thought this one was interesting because of the letter that he wrote that supposedly reveled his identity. I also thought what the letter had to say was intriguing.

and

The Bermuda Triangle-
I am quite fascinated  by the bermuda triangle and all of the disappearances that happened there. most of the stories are totally off the wall and i find the whole thing totally creepy.
