Ted Kaczynski (born May 22nd 1942), widely known as the Unabomber, was also considered a suspect in the Zodiac killings, due to his interest in ciphers and his penchant for engaging with authorities, media outlets and victims of his crimes in the form of letters and manifestos. He contacted authorities in 1995 wanting a 50 page article he had drafted called Industrial Society and its Future published in a leading newspaper or journal, stating his murderous bombing campaign would cease if this criteria was met.
His reign of terror killing three and injuring 23 people, ended on April 3rd 1996 when he was arrested in his cabin near Lincoln, Montana, where Kaczynski was living in remote isolation.
He was captured thanks to his brother David Kaczynski, who after reading the 50 page 'Unabomber Manifesto', drew parallels to letters he found written by Ted to newspapers twenty years previously using similar phrases and ideas.
His early bomb making was less sophisticated, inflicting injury rather than death. His first device in May 1978 was placed in the parking lot at Chicago's University of Illinois, return addressed to a university professor Buckley Crist. But the professor, obviously realizing he had never sent any package, contacted campus security, and it was eventually opened by police officer Terry Marker. Fortunately for Marker the bomb had design flaws, such as the use of wood which decreased the pressure the device could generate, and he survived the explosion, sustaining injuries to his left hand.
His next attacks focused on airlines, when in 1979 a bomb was discovered on an outbound flight from Chicago to Washington. The passengers and crew were extremely lucky to survive, but for a faulty timer, the device had enough energy to destroy the plane. A task force was set up and in 1980 John Douglas and the FBI Behavioral Science Unit would initially evaluate the suspect's profile as an extremely intelligent individual, with an academic degree in hard sciences.
Meanwhile, Ted Kaczynski was honing his skills, until finally his art of handcrafted bombs eventually turned deadly.
Ted Kaczynski's claimed his first main casualty, when John Hauser, a Captain in the Air Force was partially blinded in one eye and lost four fingers when receiving a mailed bomb in 1985. Hugh Scrutton who owned a California computer store, in 1985 became the first fatality of the bombing campaign, followed by Thomas J Mosser an advertising executive in 1994 and Gilbert P Murray in 1995, president of a lobbyist timber industry group.
In total Kaczynski sent 16 bombs to individuals, airlines and universities.
He is now serving four life sentences with no chance of parole.
The Zodiac link is based around his high intelligence, having acquired a PhD in mathematics from the University of Michigan, plus he excelled in geometry and calculus having taught courses at the University of California, Berkeley in 1967 where he was an Assistant Professor of Mathematics. Therefore the concept of radians and map coordinates used in the Zodiac letters would be well within the capability of Theodore Kaczynski.
Theodore Kaczynski lived in Berkeley during the time of the Lake Herman Road murders on December 20th 1968. Then on January 20th 1969 he resigned his position and drew closer to his brother David. In the summer of 1969 David experienced the troubled side of Ted Kaczynski when camping in British Columbia, where an application to purchase government land was rejected by the Canadian government. This seemed only to accelerate the already antisocial behavior exhibited by Ted Kaczynski. He moved to his parents house in Lombard, Illinois in the middle of 1969, from where in 1971 he finally purchased some land on the outskirts of Lincoln, Montana, building himself a remote one room cabin, where he would ultimately spend the remainder of his freedom, living as a recluse.
His interest in coding and knowledge of bomb making equipment are two of the main reasons people look into Theodore Kaczynski as a possible Zodiac suspect.
However he has never been linked through DNA, fingerprinting or handwriting analysis, plus he was living in Lombard, Illinois during key Zodiac timelines. In addition, he or his copious quantities of literature have never referred to any of the known Zodiac crimes, despite the fact he has little to lose after receiving his heavy prison sentence, from which he undoubtedly will never see the light of day again. He has since been cleared as a suspect by most people, including the FBI and San Francisco Police Department.
