Ok..he wasn’t really an investigator, but he was on the wanted poster. This doesn’t pertain to Zodiac, but still found it interesting considering the dates.
Here is Chief Cahill discussing the fact their is no organized crime in SF.

Nice find, Tahoe. He could have at least admitted there might have been some links of Organized Crime, if anything..
Cahill: "There is no organized crime in San Francisco.."
http://hum.uchicago.edu/~jagoldsm/Paper … _Mafia.pdf
That is what Hoover believed too in 1962, when he declared "No single individual or coalition of racketeers dominates organized crime across the nation" and then Joe Valachi sang before the Committee in front of public television. Valachi was the first insider from the Mob – from "la Cosa Nostra" – who revealed in public the nature of the internal organization and procedures which had become
so powerful and which had been so long denied by highly placed federal and local authorities.http://www.americanmafia.com/Cities/San_Francisco.html
The San Francisco LCN Family was built out of the ashes of bloody bootlegging war that took place from 1928-1932. Previously, during the ill-faded Prohibition era, gangsters worked in criminal harmony to ensure peace and prosperity with their colleagues. This all would end with a series of murders. When the smoke cleared a small but once prosperous crime family would emerge.
On April 28, 1928 bootlegger Jerry Feri, San Francisco’s leading crime lord, was murdered in his apartment. His suspected murderer, Alfredo Scariso, was an accomplished bootlegger as well and he too was murdered on December 19 of that year. His body was found with multiple gun shot wounds and dumped in the area of Fair Oaks. On December 23 Mario Filippi, a suspect behind the Scariso murder, was found shot to death. Frank Boca, another suspect in Scariso’s death, was found murdered in his car on July 30, 1929. The next murder was that of the so-called “Al Capone of the West”, Genaro Broccolo, he was found dead on October 30, 1932. The final murder was of Luigi Malvese. He had made a reputation as a hijacker, bootlegger and gun running racketeer. He was shot down on May 18, 1932 while walking through an Italian neighborhood in the middle of the day.The bloody onslaught led to the rise of Francesco Lanza. He would organize the La Cosa Nostra syndicated in San Francisco and be seen as the first true crime boss. He derived his income from bootlegging, prostitution, loan sharking, gambling and narcotics. He operated the famous Fisherman’s Warf of San Francisco with a business partner. His partner, Giuseppe Alioto would also found the International Fish Company. On July 14, 1937 Lanza died of natural causes. His son, Joseph, would later become boss over the San Francisco rackets.
Anthony J. Lima was succeeded as the next crime boss following Lanza’s death. Lima’s career is earmarked by the murder of Chicago gangster Nick DeJohn. It was believed that Lima and his underboss, Michael Abati, ordered his murder. Eventually the charges were dismissed. On April 27, 1953 Lima was sentenced to the California State Prison for grand theft. His power faded and his role was replaced by Abati.
Michael Abati would rule as street boss from 1953-1961. While boss he attended the raided mob summit known, as Apalachin in November 1957 along with is underboss Joseph Lanza. Abati was one of many who were picked up by the local police of Apalachin, NY for suspicion. The intense focus from law enforcement and the press resulted in further investigations into his activities. As a result of this he was deported back to Italy on July 8, 1961. He died of natural causes on September 5, 1962.
Joseph “Jimmy” Lanza would rise to become the most successful crime boss of San Francisco. His rule, from 1961 through 1989, was unprecedented. He would watch as his small crime family grew to include 15-20 “made” members. He was well represented in Las Vegas, NV by close associate William “Bones’ Remmer. He was their link to the casino skims. He represented the San Francisco LCN family’s interest from early 1940s to 1952 before being convicted of failing to report nearly $1 million in unpaid taxes.
Lanza was also very well connected to many other La Cosa Nostra crime family bosses. Most particular were Joe Cerrito of San Jose and Joseph Civello of Dallas. His long time underboss, Gaspare “Bill” Sciortino, was the first cousin to the underboss of the Los Angeles LCN Family Samuel Sciortino. In 1976 Lanza was believed to have given permission for the murder of former New England LCN Family associate, turned government witness. Joseph “The Animal” Barboza. Lanza paved the way for Los Angeles crime family capo and former Cleveland LCN Family associate Aladena “Jimmy the Weasel” Fratianno to open operations based out of the City by the Bay. Later Lanza would make he successfully had him removed due to the attention he had drawn upon the local crime family. This was a good move because later Fratianno would testify in multiple mob-related trials on behalf of the US government. On June 19, 1989 Joseph “Jimmy” Lanza died from natural causes at the age of 73.
The current status of the San Francisco LCN Family is unknown and is considered dormant. Law enforcement articles from investigations allege that Frank “Skinny” Velotta may the underboss or possible crime boss of San Francisco. He is a former burglar and associate to the previously mentioned Frattiano. A possible key player in the near extinct crime family is Angelo Commito.

Is three plus years too late to respond to this thread? 
There is a likely reason why Cahill said there was no Organized Crime in San Francisco. It has to do with former SF Mayor Joseph Alioto who in July 1969 was named in a Look magazine article as having aided and abetted the Mob via Jimmy the Weasel Fratianno by giving him loans while he was president of the First San Francisco Bank. Alioto ended up suing Look magazine for publishing the defamatory information and won a $12+ million dollar settlement, putting the magazine out of business.
However, Jimmy the Weasel later wrote in his memoirs that the allegations Look made were essentially true though not all the details were accurate. Alioto did not sue Fratianno.
Alioto was San Francisco’s mayor during the time that Zodiac was active killing and writing letters. It would have been in Cahill’s best interest, politically speaking, to downplay any Mob activity in SF.
From Alioto’s obituary-

Look magazine allegations
By then, his political prospects had been wrecked by a story in Look magazine alleging that a "web of alliances" linked San Francisco’s Italian American mayor to organized crime.
Among many other allegations, the 1969 story asserted that Mr. Alioto, while a lawyer and president of First San Francisco Bank, had arranged loans for a mob-infiltrated trucking company owned by Aladena "Jimmy the Weasel" Fratianno, an ex-convict and admitted Mafia hit man.
Mr. Alioto proclaimed his innocence and sued for libel, pursuing the dispute through two trials. Eventually, a jury ruled that key details in the magazine story, including allegations of nighttime meetings between Mr. Alioto and Mob kingpins at the old Nut Tree restaurant in Vacaville, were a tissue of lies.
Mr. Alioto won $12.5 million from Look, and by the time the litigation was over, the magazine had been driven out of business.
Later in life, Mr. Alioto said he had obtained documents under the U.S. Freedom of Information Act showing that the Nixon administration had leaked false information about him to Look in the hopes of destroying the career of a promising Democratic politician.
For his part, Fratianno remained silent through Mr. Alioto’s extended battle with Look. But in 1981, after defecting from the Mafia and becoming a government witness in several high-profile racketeering trials, the mobster gave a series of interviews for his biography,
"The Last Mafioso."
In the book, Fratianno repeated many of the same allegations about Mr. Alioto and the Mob that appeared in Look. But the former gangster said the tale of the meetings at the Nut Tree was a lie concocted by his alcoholic son-in-law and presented to Look as fact.
"The Last Mafioso" became a best-seller, and this time Mr. Alioto did not sue.
By then he had retired from politics and was making a second career out of whipping the National Football League in antitrust actions.
A neighbor who used to work for the Oakland PD, said that there was no mobs or organized crime there but when there was mafia gangster, they took him across the Bay bridge back to SF.
