Corey Starliper of Tewksbury, Massachusetts
believes he has solved the last
Zodiac serial killer cipher and has identified the person who terrorized northern California in the late '60s. "Zodiac sent encrypted communication to area newspapers, taking credit for the killings and warning of more to come ..." His most famous: a 340-character cipher, "was mailed to the San Francisco Chronicle, according to
zodiackillerfacts.com. To this day, the cipher has not been completely cracked. Starliper, however, believes he has found the solution to that code."
