Big problem with his suspect William Joesph Grant  from Fairfield  who was93  and is now deceased . He was cleared years ago that includes with DNA.

By Lyndon lafferty making these false claims he should be charged with obstruction of justice.  We have it on good authority that Mr. Lafferty is impossible to talk to and is prideful and stubborn.

He pays off the women he uses as witness’s and falseley accuses those who go against his theories.

It is almost to the point of being obsessive .  Hmmm maybe a bit of a mental illness manifesting?It also destroys and puts up false flags that detour away from the real killers.

This though seems to be very typical with the Zodiac murders. It becomes about pride instead of helping the real victims in this…. the families of the murdered victims.

And if any of you are stupid enough to pay $45 dollars for his book than you deserve it. Just another Zodiac superstar wanna be in an endless stream of people seeking fame at these poor families expense.

The author of a new book about the Zodiac Killer, who struck Northern California four decades ago, claims there was a massive law enforcement coverup that prevented the killer from being caught.

“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.

According to Lyndon Lafferty, who penned a new book titled The Zodiac Killer Cover Up, the killer is still alive and living Solano County.

“No doubt in my mind at all. I would say that I am 95 positive we have the right man,” said Laferty, who claims the 92-year-old lives in Fairfield. “I know for a fact that he does.”

Lafferty said a the suspect was never arrested because of a cover up by District Attorneys, Sheriff’s Department officials and one particular judge.

“The judge (was) having adulterous affairs with the suspects wife,” Lafferty claimed.

Lafferty, 79, does not name the suspect or the judge in his 440 page book. The former CHP officer was on patrol for 16 years. In November 1970, he claims he came face to face with the killer in the parking lost of the Hunter Hill rest stop off of I-80 in Vallejo.

“(It was) like I was looking into the eyes of death,” said Lafferty, who claimed that no law enforcement agency would take him seriously. “Their attitude is, unless the suspect is their own, they don’t want to talk to you,” Lafferty said.

For decades, Lafferty and six other former cops and investigators tracked the Zodiac Killings suspect through Solano County, watching him marry and even attend Alcoholics Anonymous meetings.

“I’ve gone through 40 years of frustration,” said Lafferty.

Lafferty said he won’t release the name of the suspect because he doesn’t want to put a target on the back of a 92-year-old.
