"The Zodiac Killer" by Robert Graysmith is not a banned book. It is a true crime book that delves into the infamous unsolved case of the Zodiac Killer and has been widely available for purchase and reading.

The Zodiac Killer is believed to have killed at least five people in California throughout the late 1960s. These are the confirmed victims: David Faraday, Betty Lou Jensen, Darlene Ferrin, Michael Mageau, and Paul Stine. However, there could be more victims that we don't know about.

No, the first officially confirmed Zodiac Killer murder occurred in December 1968. However, the Zodiac Killer claimed responsibility for earlier killings in anonymous letters, but those claims remain unverified.

Possibly. One of the best suspects in the Zodiac murders was an ex-school teacher and pedophile named Arthur Leigh Allen. Allen died in 1992 of natural causes before he could be arrested.

Zodiac's confirmed victims: David Faraday (died), Betty Lou Jensen (died), Michael Mageau (survived), Darlene Ferrin (died), Bryan Hartnell (survived), Cecelia Shepard (died), Paul Stine (died.)

Suspected victims: Robert Domingos (died), Linda Edwards (died), Cheri Jo Bates (died), Donna Lass (missing, presumed dead) and Kathleen Johns*.

*Johns was abducted by a man she identified as matching the Zodiac's description. She was able to escape with her infant daughter. She was also seven months pregnant at the time.

For the few that actually saw him and lived to tell their stories described him as a white male, approximate height of 5'9" to 5'11", stocky build, age 35 to 39 years old and had a lumbering gait. The Lake Berryessa victim Bryan Hartnell was the only surviving witness to see him in full costume. Black clothes, black hood over his head with eyeholes, black boots and a gunsight emblem (or crosshair) on his chest.

July 4th surviving victim Michael Mageau picked suspect Arthur Leigh Allen out a photo lineup 20 years after his attack.

67 years old.

I depends on who you think the Zodiac was. If you go by the bestselling book by Robert Graysmith then the Zodiac would be 77 years old. Arthur Leigh Allen, born in Hawaii and lived in Vallejo, California at the time the murders began.

Recently there was DNA testing on some envelopes from some of Allen's correspondence but it did not match Allen's. But there was no proof that he licked his own envelopes personally. Allen had a nearly genuis IQ, and although DNA was not possible when the Zodiac crimes were commited, Allen was smart enough to not put anything of a personal nature that could in anyway lead back to him.

After Graysmith's book was published, police were getting ready to bring him in when he suffered a fatal heart attact. Graysmith puts out a pretty strong argument for Allen being the killer. In fact, in his research he found that Allen used to visit Southern California on a regular basis, and his visits south align with several murders around L.A.

The first Zodiac attack killed Betty Lou Jensen and David Faraday on Lake Herman Road in Benicia, California on December 20, 1968. The last officially recognized murder was of San Francisco Yellow Cab driver Paul Lee Stine on October 11, 1969. However, Zodiac claimed responsibility for the murder of Cheri Jo Bates on October 30, 1966 in Riverside, California. That was the first ever unsolved murder in the history of Riverside. The Riverside Police Department does not believe that was done by Zodiac. However the RPD's prime suspect was cleared through DNA testing. There are 5 confirmed Zodiac murders but in a letter sent in 1974 Zodiac claimed 37 victims.

Due to the massive amount of circumstantial evidence against suspect Arthur Leigh Allen, the odds that Zodiac could be anyone other than Allen is astronomical.

Good answer.

One of the evidence against Allen is the code message stating his name as the culprit.

Nothing definitive is known about the Zodiac's background since he was never caught. But his crimes were murders since he was a serial killer. He killed with a pistol and with a knife.

It would have been very foolish of the killer to actually use his own name, especially a name like Zodiac which is a very uncommon name, one that people would remember easily.

Vallejo, CA resident Arthur Leigh Allen was and still is the best suspect for the crimes of the Zodiac. Unfortunately Allen died in 1992 before he could be charged with the murders, some of them over 30 years old at the time of his death.

No he wasn't because he was an Organized serial killer. A paranoid schizophrenic would be an Unorganized Serial Killer. The Zodiac was methodical and meticulous in his killing.

An FBI geographical profiler placed the Zodiac's home in or close by the northern California town of Vallejo, making Arthur Leigh Allen a serious suspect. However Allen's handwriting, fingerprints and palm print did not match the evidence in the case. In 2003 a partial DNA profile of the Zodiac was obtained and it's comparison showed that Allen was not the Zodiac, someone that he denied being until his dying day in 1992.

There are over 2,500 suspects that have been suggested as having been the Zodiac. Only Arthur Leigh Allen has ever been served with a search warrant - and he was not arrested! No one has EVER been arrested, much less tried in court in this case. So it is impossible to know for certain where the Zodiac Killer lived.

The Zodiac sent zero letters to the SFPD. All of his letters were addressed to newspapers, a Los Angeles television station and some individuals including famed attorney Melvin Belli. There was a phone call to the Oakland PD by someone claiming to be the Zodiac on October 22, 1969. The San Francisco Chronicle newspaper received by far the most of Zodiac's correspondence.

The original Zodiac killer was never caught so insight into his childhood is difficult at best. The most likely suspect, Arthur Leigh Allen of Vallejo, CA, had a strained and difficult relationship with his mother. His father, an Air Force officer, sustained injuries at work that left him a shadow of his former self. This is a common enough scenario with violent criminals, a strong or domineering mother and quiet or meek father. But compared to other serial killers, Allen's childhood was a breeze.

There has not been a definitive answer as to whom the Zodiac Killer really was. So whether he is still alive remains a mystery.
It depends on who you believe the Zodiac is, or was. The best suspect police had died in 1992. Vallejo resident Arthur Leigh Allen died in August 1992 before an arrest could be made.

The Police were never sure if the suspect they had found, Arthur Leigh Allen, was the Zodiac killer or not. Most evidence points to him, but the Police did not have enough sufficient evidence to legally throw him in prison. However, most believe that the Zodiac killer was Arthur Leigh Allen.

The case is limited to search warrents. Zodiac was never caught or tried in court, which kept legal prceedings to a bare minimum.

The Zodiac Killer was a serial killer who operated in Northern California. The first murders were on December 20, 1968. He coined his name in a series of taunting letters he sent to the press until 1974. His letters included four cryptograms, three of which have yet to be solved.

The Zodiac murdered five known victims in Benicia, Vallejo, Lake Berryessa (near Napa), and San Francisco between December 1968 and October 1969. Four men and three women between the ages of 16 and 29 were targeted, and no connections between them have ever been discovered; they appear to have been victims of opportunity, nothing more. In his letters Zodiac claimed 37 kills.

While it is often claimed that the Zodiac knew his victims, there has never been any credible evidence to suggest this was true. Numerous others have been thought to be Zodiac victims, although the evidence is scant at best. The killer's identity remains unknown. The San Francisco Police Department marked its investigation "inactive" in April 2004 but reopened the case in 2007. The case remains open in other jurisdictions.

He is, or was very real. Credited to seven murders or attempted murders and suspected of another five, the Zodiac's most active period was the 1960's and 1970's, he terrorized the state of California for two decades.

since the zodiac killer's identity is unknown, we might never learn the reasons that moved him to do such things. He had to suffer some mental illness clinically speaking.

But if he is dead he did not leave a bragging note confessin after death so everyone knew who fooled the police until the end which makes me believe he had a violent death that not necesarily had to to with his serial killings.

No he would probably be dead by now but investigators think that might have found someone. Who admitted to his friends several times that hes the zodiac killer. However he did die so no one is for sure.

///There are few reasons why a serial killer stops killing. Death or a serious illness, incarceration for other crimes, moving from the area, or they actually just get too old and finally fade away. One of these reasons are responsible for the 'disappearence' of the Zodiak. Although there have been several new suspects in the last year or so, they have failed to close the case. After the bestselling book Zodiak was published*, it breathed new life into this cold case. The detectives were preparing to make an arrest when their main suspect died of natural causes while in jail. Arthur Lee Allen, a long-time resident of Vallejo, CA, had been the detectives' first choice as the Zodiak at the time of the murders. If Allen was the Zodiak he falls into one of the catagories above. He was diabetic and over the years his health was in a downward spiral. He died of complications of diabetes.

The Zodiac killer disappeared because he realized the police had his fingerprints although he claimed that he never left prints behind. The Zodiac used phrases that clearly told you he had a teaching profession. (As you can see) or ( as you see) is one example he has used in many letters.The talk of school children was also an important clue to his idenity. Arthur Leig Allen was cleared on this evidence and hand writing. I have a good idea of who it was and he was so kind to offer to help with the investigation.

Giving it a little though I came to my conclutions that the zodiac killer died before he wrote the bragging note letting everyone know who he was when died. I take this he had a sudden death or a violent one not related to his killings. A serial killer that was never caught would leave a bragging note so everyone finds out who fooled the police all the way to be release at their death date.
