The Zodiac Killer

The Zodiac killer is arguably the most infamous, unidentified serial killer of all time. He was active in Northern California in the late 1960’s and early 1970’s. Although the Zodiac Killer claims to have murdered 37 people, investigators have only been able to link him to 5 deaths and 2 injuries.

During his killings, the Zodiac Killer would send letters to the police, taunting them. He would make demands, give them cryptograms to solve in order to reveal his true identity, and he would tell them about upcoming attacks. His final letter concluded with “Me=37, SFPD=0.”

No one has ever been formally charged, though Texas Sen. Ted Cruz has been cautiously suspected…
