The elusive Zodiac Killer has taunted police for decades, in one of the most notorious cold cases of all time and now a new bombshell book claims to have evidence that will finally solve the 44-year-old Northern California case.
Written by former California Highway Patrol officer, Lyndon Lafferty, The Zodiac Killer Cover Up proposes the theory that the serial killer who claimed seven – five dead and two injured - victims between December 1968 and October 1969 is now a 91-year-old man living in Solano County, California.
Instead of naming his culprit, Lafferty uses aliases and reveals that he and other law enforcement officers and government officials (known as the Mandamus Seven) have known the identity of the suspect since March 1971 but were kept quiet by "power brokers" in the opulent neighborhood.
“I know what most people think of Zodiac theories, and there have been so many over the years that if a person walked into the Vallejo Police Department right now and said he was the Zodiac, they'd tell him to get out," Lafferty told the San Francisco Chronicle in an interview last year.
"But I do feel that we have a very credible case,” said the ex-cop, who claims the killer was motivated by jealousy because his wife was having an affair and he was driven to blood-lusting revenge after years of alcoholism.
As RadarOnline.com previously reported, the shooter taunted the Bay Area police with cryptic letters including a 408-symbol cryptogram which he claimed contained his identity that was sent to San Francisco newspapers.
"The police shall never catch me, because I have been too clever for them," the Zodiac wrote in a letter sent to the San Francisco Chronicle. "I enjoy needling the blue pigs," he boasted, referring to the police, and claimed to have killed as many as 37.
Many of the victims targeted were couples in popular make-out spots who were gunned down or stabbed by a man whom one survivor described as wearing a black executioner's-type hood with clip-on sunglasses over the eye-holes wearing a bib-like device on his chest that had a white cross-circle symbol on it.
In his expose of the confusing case, Lafferty claims that the killer, who was among 2,300 suspects cleared by the local authorities, escaped justice thanks to “secret oaths and federal obstructions of justice,” and his intrepid wife who protected him from prosecution.
