Author claims huge coverup in Zodiac Killer investigation
"The Zodiac Killer Cover Up" is a new book written by a former California Highway Patrol officer, Lyndon Lafferty.
Lafferty claims the killer is now a 91-year-old man living in Solano County. The book uses aliases and does not identify the alleged killer by name. Lafferty claims he and other lawmen investigated the suspect in the early 1970s but were stymied by "power brokers" in Solano County. Lafferty claims the killer was motivated by jealousy because his wife was having an affair.
The Zodiac Killer is blamed for at least five slayings in 1968 and 1969. There was never an arrest in the case.
In an interview this week with ABC News, Lafferty claims the killer was protected.
“The police departments in general were acting under the authority of the Solano County sheriff, so they were instructed you do not investigate this man until you have permission from the judge,” he said. “It’s been very traumatic, and it’s been frustrating beyond belief.”
Lafferty added: “I am the only person who can testify under oath that these things were absolutely true. My satisfaction is telling my story as it happened.”
Three killings occurred in Vallejo. Teenagers David Farraday and Betty Lou Jensen were shot to death in December 1968. Darlene Ferrin, 22, was shot and killed seven months later at Blue Rock Springs Golf Club. Her companion, Michael Mageau, 19, survived.
The Zodiac killer got his name by taunting newspapers and the police with letters and puzzles.
"The police shall never catch me, because I have been too clever for them," he wrote in a letter sent to the San Francisco Chronicle.
"I enjoy needling the blue pigs," he wrote. Detectives thought they might have had a break two years ago, when a partial DNA profile was taken from envelopes containing the letters.
The genetic evidence seemed to clear the only suspect ever named by police -- Arthur Leigh Allen of Vallejo. Allen, who was never charged, died of a heart attack in 1992.
