Victims of the Zodiac Killer

Many cases have been examined in regard to possibly being Zodiac victims; however, only seven victims in four attacks have been confirmed by law enforcement to allegedly be the works of this predator.  The claim of thirty-seven victims has never been substantiated through verifiable evidence.   

The two survivors gave descriptions of the attacker.  In one of the attacks his face was seen.  In the other, he was wearing a mask.  There were also witnesses of one attack who shared descriptions of the killer.  Composite were made and distributed in attempts to identify the serial murderer.

Many suspects have been investigated in this cold but active case.  It has been almost half a century since the terror of the Zodiac began.  Attempts have been made to decode cryptograms to discover the identity of the Zodiac.  One was decoded, but didn't seem to help much in solving the mystery.   

Many theories have been developed by law enforcement and amateur investigators.  Death bed confessions have been looked into.  With enhancements in forensic science and technology, evidence collected earlier in the case has been reanalyzed. 

A lot of effort and resources has gone into investigating the serial murders of the Zodiac; however, this chilling case remains unsolved.  The serial killings seem to have stopped, but the questions regarding these random attacks lives on.
