This shirt is simple. It doesn't need to be complicated up with layers and elements to create a story. The true story is enough. The Zodiac Killer was a serial killer who operated in northern California in the late 1960s and early 1970s. He wrote letters to the newspapers and police and used a 408 symbol cryptogram to hide his messages. He claimed these letters contained his identity. He also used them to make threats and demands to and about the newspapers and police. The case remained open and unsolved until 2004 when it went inactive. It was reopened in 2007. There are many theories about who the killer was or is and many suspects were investigated. We likely will never know if the Zodiac lives or has already died. This case is one of several that fascinate both Jim and Connie. The vIsual element is very compelling and the brutality of the murders is completely frightening. The fact that this guy was seemingly trying to get caught and remains possibly free to this day ranks the Zodiac Killer tops on the PM list of mysteries. We encourage you to read up on the Zodiac online and to watch the 2007 David Fincher film Zodiac to familiarize yourself with one of the most fascinating crime cases ever. Oh and we encourage you to get in the club and wear ZODIAC by Print Mafia.
