Zodiac Killer - Current Status of Investigations

Current Status of Investigations

In April 2004, the SFPD marked the case "inactive," citing caseload pressure and resource demands. However, they re-opened their case sometime before March 2007.

In 2007, a man named Dennis Kaufman claimed that his stepfather Jack Tarrance was the Zodiac. Kaufman turned several items over to the FBI including a hood similar to the one worn by the Zodiac. According to news sources, DNA analysis conducted by the FBI on the items were deemed inconclusive in 2010. Kaufman's claims have later been widely discredited. He claimed to have incriminating rolls of film taken by his stepfather. The photos allegedly showed victims of the crimes. Kaufman later published some of these photos on his own web page. The photos were very small, had low resolution, and were so blurry that nothing could be positively identified. An associate of Kaufman's, Nanette Barto, who received her Forensic Document Examining certificate from an unaccredited school, claimed to have matched Jack Tarrance's handwriting to that of the Zodiac Killer. However, in 2010, the FBI's Head Document Examiner at Quantico deemed the handwriting "Inconclusive".

In 2009, Deborah Perez claimed that her father, Guy Ward Hendrickson, was the Zodiac. However, Perez also allegedly previously claimed that she was the illegitimate daughter of John F. Kennedy, so her claim that her father was the Zodiac has been viewed as unlikely.

In 2009, a lawyer named Robert Tarbox (who, in 1975, had his law license suspended in California for failure to pay some clients) said that in 1972 a merchant mariner walked into his office and confessed to him that he was the Zodiac Killer. The seemingly lucid seaman (whose name Tarbox would not reveal due to confidentiality) described his crimes briefly but persuasively enough to convince Tarbox. The man claimed he was trying to stop himself from his "opportunistic" murder spree but never returned to see Tarbox again. Tarbox took out a full-page ad in the Vallejo Times-Herald in which he cleared the name of Arthur Leigh Allen as a killer, his only reason for revealing the story 30 years after the fact. Robert Graysmith, the author of several books on Zodiac, said Tarbox's story was "entirely plausible." Retired police handwriting expert Lloyd Cunningham, who worked the Zodiac case for decades, added "they gave me banana boxes full of Allen's writing, and none of his writing even came close to the Zodiac. Nor did DNA extracted from the envelopes (on the Zodiac letters) come close to Arthur Leigh Allen."

In 2009, an episode of the History Channel television series MysteryQuest looked at newspaper editor Richard Gaikowski (1936–2004). During the time of the murders, Gaikowski worked for Good Times, a San Francisco counterculture newspaper. His appearance resembles the composite sketch and Nancy Slover, the Vallejo police dispatcher who was contacted by the Zodiac shortly after the Blue Rock Springs Attack, has identified a recording of Gaikowski's voice as being the same as the Zodiac's. Additional circumstantial evidence exists but cannot definitively connect Gaikowski to the murders.

The Vallejo Police Department website maintains a link for providing Zodiac crime tips. The case is also open in Napa County and also in the city of Riverside.

Retired police detective Steve Hodel argues a case in his book The Black Dahlia Avenger that his father, George Hill Hodel, was the Black Dahlia suspect whose victims include Elizabeth Short. The book caused the release of previously suppressed files and wire recordings by the Los Angeles district attorney's office of his father which showed that he was a prime suspect in Short's murder. The L.A. District Attorney subsequently wrote a letter which is published in the revised edition stating that if he were still alive he would be prosecuted for the crimes. In a follow up book, Hodel argued a circumstantial case that his father was also the Zodiac Killer based upon a police sketch, the similarity of the style of the Zodiac letters to the Black Dahlia Avenger letters and questioned document examination.

On February 19, 2011, America's Most Wanted featured a story about the Zodiac Killer. A picture has recently surfaced of known Zodiac victim Darlene Ferrin and a man who closely resembles the composite sketch, formed based on eyewitness' descriptions, of the Zodiac Killer. Police believe the photo was taken in San Francisco in the summer of 1966 or 1967. Police hope someone can identify the man in the photo. It has been suspected that the man in the photo is Darlene Ferrin's ex-husband, James Phillips. This has not been confirmed.

A former California Highway Patrol officer, Lyndon Lafferty in a 2012 book The Zodiac Killer Cover-Up, AKA The Silenced Badge argues that the Zodiac killer is a 91-year-old Solano County, California man whom he calls "George Russell Tucker." Using a group of retired law enforcement officers called the Mandamus Seven, Lafferty discovered "Tucker" and a cover-up for why he was not pursued. The man died in February 2012 and is not considered a suspect by law enforcement agencies.

Famous quotes containing the words current and/or status:

    It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a woman’s adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.
    Terri Apter (20th century)

    What is clear is that Christianity directed increased attention to childhood. For the first time in history it seemed important to decide what the moral status of children was. In the midst of this sometimes excessive concern, a new sympathy for children was promoted. Sometimes this meant criticizing adults. . . . So far as parents were put on the defensive in this way, the beginning of the Christian era marks a revolution in the child’s status.
    C. John Sommerville (20th century)
