Ted Cruz is a politician that is the Senator of Texas. He also ran for president in 2016. Ted Cruz is most likely not the Zodiac Killer and it started circulating around the internet because of social media.
- Cruz was born in 1970 and the Zodiac murders started in the 60's. As of then he wasn't even born yet. This also means that he couldn't have committed the murders in the 70's because he would have been a little kid. Sketches of the Zodiac show him as a man in 30's or 40's not a child.
- It's most likely just a joke.
