the unabomber and the zodiac killer are NOT the same person. there is proof that the unabomber was states away from CA when certain letters were sent. there is a book about this, written by the guy who made the zodiac books but the argument could be made that if the unabomber was the zodiac then the info in he zodiac books was all false, but... there are other writings where it is proven that they were not the same person.
