When Dennis Kaufman was dealing with the aftermath of what he believed was the murder of his mother Nora Kaufman Tarrance circa 2000, a show came on about the cold cases of Zodiac Killer, he was convinced his stepfather who he believed killed his mother, was it. From there, for Dennis, it evolved into a long, journey of dealing with FBI agents, message boards online, news agencies and a stepfather trying to confess he was the real Zodiac but in ways not many would understand. After Jack died, Dennis met Forensic Document Examiner Nanette Barto whom after 5 reports for the FBI had nailed that Jack was the creator of the Zodiac era letters. I ended up meeting both and doing my best to work with them to help prove Jack was the real Zodiac. Dennis, who died 2018, himself, approved of me continuing my efforts to crack Jack's ciphers, cryptic messages that span decades in 2014. During my own crisis as a 8/14/16 fire victim, Nanette kept inspiring me to dig in deep and keep trying.
