Criminal Profiling in The Zodiac Killer Case by: David
Check out the official website for David Fincher's Zodiac film not only can you find out all about this infamous serial killer case, but you can also watch videos discussing the case in relation to Geographic Profiling, Behavioral Profiling & Linguistic Analysis.
Last year I did a forensic psychology blog post on Douglas Evander Oswell who has spent over 10 years researching the methods, motives, psychological attributes and connection between the Unabomber and the Zodiac.
This forensic psychology blog post (see following link) included a link to an interview with Oswell in which he outlines the striking connections between the two cases as well as discussing the distinction between serial killers, recreational killers and mass murderers.
