The Zodiac Killer

During the late 1960s, a serial killer was on the loose in the San Francisco Bay Area. Records have it that the killer has claimed the lives of five confirmed victims, two of them were men and three were women between the ages of 16 and 29. The Zodiac was also presumed to be behind twenty to twenty-eight more murders and three failed attempts, which occurred during that time as well.
