Lafferty’s book — “The Zodiac Killer Cover-Up, AKA The Silenced Badge” — uses a pseudonym for his suspect, but in 442 pages, he lays out quite the case. Across the nation, at least a dozen law enforcement officials - both active and retired -have taken it upon themselves to try to solve the mystery of the killer who fatally shot or stabbed five people in the Bay Area in 1968 and 1969 and sent almost two dozen taunting letters stuffed with cryptograms to individuals and newspapers, including The Chronicle, until 1974. It’s been 40 years in the making, but ex-California Highway Patrol Officer Lyndon Lafferty’s book about the man he believes is the Zodiac killer has been released. Leslie Lundblad, but that the case was squelched by power-brokers in the county — including a judge who was having an affair with the suspect’s wife. After Jack the Ripper, it's probably the most infamous unsolved murder case in history - and police are drawn to unsolved mysteries like cats to catnip, McMahon said.
– The Zodiac killer who terrorized the San Francisco Bay Area is still living in northern California, says a new book by a former state police officer. The Zodiac is blamed for at least five slayings beginning in 1968. No one was arrested for the murders, and police stopped hunting for the killer 2004. Former Highway Patrol Officer Lyndon Lafferty is convinced the Zodiac is a 91-year-old alcoholic living in Solano County, who Lafferty refers to using a pseudonym because of safety concerns. His case is strong, indicates the San Francisco Chronicle, which received two dozen taunting letters from the Zodiac during his bloody spree. Lafferty told the Chronicle in an earlier interview that he discovered the suspect's name spelled out in the cyphers that marked the Zodiac's letters to the newspapers. Lafferty helped investigate the case on the job after the murders, and says in his book, The Zodiac Killer Cover Up, that he developed solid leads linked to his suspect. The information was squelched by officials, however, including by a judge having an affair with the suspect's wife, says the former cop. Lafferty wrote the book with help from six other investigators, some of whom worked the case while it was unfolding. “As God is my witness, my partners and I have always tried to share our material and our case with the proper authorities, but in the past 40 years the latter have ignored and stymied and stonewalled us again and again,” Lafferty writes. Police will only say that the case remains unsolved.
