As of 2014, the case of the Zodiac Killer remains unsolved. The San Francisco Police Department and California Department of Justice claim to have investigated thousands of potential leads without being able to conclusively determine the person responsible for these infamous murders.
The Zodiac Killer case involved a series of murders in the 1960s and 1970s in the northern California area. Seven victims were targeted over the course of several years, and the cases became famous due to taunting cryptograms and puzzles the killer sent to the police and area press. Suspects have come forward and new identities have been proposed for the Zodiac Killer as recently as 2014, but there has never been enough conclusive evidence to solve the case.
