After more than fifty years of failure by professional investigators, these enthusiasts used modern computing and collaborative persistence to reveal a message centered on taunting and narcissism. The narrative explores the killer's regional reign of terror in Northern California and his calculated use of cryptograms to secure publicity and control. While the decoded text did not reveal a specific identity, it confirmed the offender's disturbed psychological themes regarding the afterlife and his desire for superiority.
