In the late 1960's a mysterious, middle-aged, white male began killing people seemingly at random in northern California. Soon after he would send a letter to a newspaper naming himself Zodiac. Who was this unknown serial killer? No one has been able to discern his identity. That ends today. Take a listen to this episode to find out who the Zodiac Killer really was. And I cannot stress this enough...it's not Ted Cruz. We aren't having this conversation again.
