The Zodiac was a notorious, never-caught serial killer in California in the late '60s and early '70s, who taunted the police with a series of puzzles and codes. At the time of the Zodiac's first murders, Ted Cruz (born 1970) was not even a little Canadian foetus.
Some people claim that this makes it impossible for Ted Cruz to be the Zodiac killer! But consider the following evidence:
* Ted Cruz has not denied being the Zodiac killer
* A time-travelling serial killer is even creepier than a normal serial killer
* Lots of people keep saying that Ted Cruz is the Zodiac killer
* Ted Cruz is the Zodiac killer
So far it seems fair to say that the jury is out on the issue of Ted Cruz being the Zodiac killer.
