Mini Lecture: How Psychology could lead to finally solving the Zodiac serial killer mystery

From 1968 to 1972 an unknown serial murderer killed 5 people and nearly killed 2 more in Northern California. His reign of terror only ended when he simply disappeared in 1972, having never been identified. The Zodiac killer wrote dozens of postcards, letters, puzzles and sent drawings and objects to the Police and Newspapers, with some very complex codes to be cracked, that could reveal his identity. He would not stop writing - all of which proved to be a huge pile of 'psychological' evidence. Using modern forensic evidence, criminal psychology, and the techniques of STEM, this session shows it is possible that the Zodiac could finally be identified. Over 50 years after the crimes, the  San Francisco police have left the case 'open' . . . Perhaps one day it might be closed.
