Jump to Menu

Toronto-based Edmond Valin uses publicly available information, including declassified files of the U.S. Federal Bureau of Investigation, to track down the identities of underworld informants officially referred to only by code numbers or codenames.

Willie the Tile Maker passed Mafia secrets to Feds

William Dara


"In the late 1960s, a Florida-based member of the Bonanno Crime Family began to cooperate with the FBI. He shed light on gangland murders, spilled secrets about LCN members and gave the FBI a front row seat to the turmoil within the Bonanno organization. His cooperation was never suspected by his crime family, and he died a member in good standing. Now, clues found in declassified FBI documents may help to reveal his identity for the first time..."

Two Gambino Family informants had very different fates

Carmine Lombardozzi


"On July 11, 1963, two men wearing makeup disguises entered the Flowers By Charm flower store in Brooklyn, New York, and fired five bullets at the owner before fleeing. Lying dead on the floor was forty-year-old Gambino Crime Family member Alfredo Santantonio... Informant Gregory Scarpa told the Federal Bureau of Investigation that "it was common talk in Brooklyn that [Santantonio] was killed because he was cooperating with the Government."

Two inducted members provided info on Philly Mob

Harry Riccobene


By the early 1960s, the Federal Bureau of Investigation was able to persuade two members of the Philadelphia Crime Family to reveal confidential information about La Cosa Nostra. The informants were sons of prominent LCN members who could trace their crime family connections to the 1920s. They provided agents with an inside look at the history, structure and membership of the Philadelphia Crime Family back to its earliest days.

Banana War informant: Did Bonanno's son cooperate?

Bill Bonanno

Bill Bonanno

Salvatore “Bill” Bonanno's quick rise within the Bonanno Crime Family divided the membership and set off a shooting war that the press dubbed the “Banana War.” The conflict reshaped the New York underworld and took down the last remaining boss of New York’s original five families. The Federal Bureau of Investigation had a front row seat to it all after they developed a secret source at the crime family's highest levels.

Post-Giancana Outfit was fertile soil for FBI informants

Louis Fratto


Declassified FBI documents show that more than ten Chicago Outfit members began to "talk" soon after Sam Giancana was deposed as boss and fled Chicago. The turnaround, up from virtually zero high-value informants in 1965, was due primarily to a more aggressive approach by law enforcement and the ongoing turmoil within the Outfit after a succession of bosses were quickly jailed.

Roemer's Men in the Outfit: 'Sporting Goods' and 'Romano'

William Roemer


According to Roemer, the three “best” Outfit informants were Richard Cain and two others who to this day are known only by their codenames, "Sporting Goods” and “Romano.” But who were "Sporting Goods" and "Romano"? A careful reading of Roemer’s books provides compelling clues. When combined with declassified FBI reports, the identities of these informants can finally be revealed.

Bay-Area informants proved crucial for FBI



As the FBI entered the fight against organized crime on a national level, it benefited from membership data and organizational history obtained through confidential informants from a small Mafia family in northern California. For a brief period in the 1960s, there may have been more member-informants active in San Jose than any other LCN crime family. Their cooperation left the FBI better informed about the Bay Area underworld than its local boss Joseph Cerrito.
