Diaz was born in New York City on February 25, 1946 and grew up in Red Hook, Brooklyn. He was the son of Spanish parents from the north of Spain. Diaz attended Most Holy Trinity High School in Brooklyn. After he graduated, he studied at St. Francis College, also in Brooklyn and at Queens College in Queens, New York, where he received his B.A. degree.Jack Murphy, "A Cop Who Busts Drug Dealers Jaws", ''San Diego Union'', August 27, 1978. In 1964, Diaz was a welterweight boxing finalist in the New York Daily News Golden Gloves.

Diaz served in the United States Army. He was stationed in Germany where, as an amateur boxer, he won the 3rd Armored Division's middleweight championship.

In 1971, Diaz was hired by the Bureau of Alcohol, Tobacco and Firearms (ATF) where he served as an undercover agent. While at ATF, Diaz made many high-profile gun cases and arrested many organized crime members.

In 1975, Diaz was hired by the Drug Enforcement Administration (DEA) in New York City where he served 28 years as a special agent, 22 of which were spent working in an extensive undercover capacity.Nathan M. Adams, "Target: Mr. Untouchable", ''Reader's Digest'', June 1978

Nicky Barnes organization investigation

In 1975, Diaz's talents as an undercover agent caught the attention of his DEA superiors who assigned Diaz to the Nicky Barnes investigation. During the course of this investigation, Diaz infiltrated the Barnes organization at its highest levels, purchasing heroin and laundering money for Barnes' immediate subordinates and obtaining direct evidence against Barnes himself. Diaz spent one year around Barnes and his associates. Barnes was subsequently arrested and convicted on a myriad of drug charges including conspiracy. Barnes was sentenced to life in prison without possibility of parole. Diaz was also largely responsible for "taking down" all of the primary members of Barnes' drug trafficking organization known as the "Council."

This case involved the direct intervention of President Carter who ordered the then U.S. Attorney General, Griffin Bell, to see that Barnes was tried and convicted to the full extent of the law. The Barnes case was the first federal trial in the United States in which an anonymous jury was impaneled because of Barnes' reputation to coerce or bribe the witnesses.

Operation Henry

In 1982, Diaz was then involved in Operation Henry, an undercover investigation. Diaz and his partner worked with members of Scotland Yard in London in pursuit of a gang of British criminals who were involved in the sale and distribution of large quantities of heroin. During the course of this investigation, Diaz and his partner negotiated the sale of forty kilos of heroin with Ron Leslie, the principal subject.

Leslie was responsible for the escape of Ronald Biggs from Wandsworth Prison. Biggs was one of the gang responsible for the 2.6 million pound Great Train Robbery in 1963. This case was the first time that DEA agents served as '' agent provocateurs'' for a country other than the United States. Subsequent to the arrest of Leslie, British authorities seized the 40 kilos of heroin.Barry Koltnow, "A tough guy for hire", ''The Orange County Register'', March 27, 2011

Operation Pisces

In 1986, Diaz was one of the principal undercover agents in Operation Pisces, an international operation involving Colombia and Panama. During the course of the investigation, Diaz laundered over 50 million dollars for members of the Medellin cartel including Jose Lopez and Alfonso Reyes, who were close associates of Pablo Escobar. Lopez and Reyes were subsequently arrested in a major dragnet which saw the arrest of over 350 defendants nationwide and the seizure of over 9 tons of cocaine and over 100 million dollars in cash and assets. According to the former U.S. Attorney General, Edwin Meese, Operation Pisces remains the largest most successful undercover drug investigation in the history of the United States.Miles Beller, "A life in crime – fighting it that is", ''Los Angeles Times'', December 18, 2010.

Operation Blast Furnace

In 1988, the United States government, along with Victor Paz Estenssoro's government in Bolivia, launched Operation Blast Furnace, whose mission was to eradicate Bolivia's illegal coca producing fields and clandestine cocaine-producing laboratories located in the Chupari and Bene jungle regions. Diaz was a major participant. He flew 26 missions with the 210th combat air-wing out of Panama. Together with members of the 210th, he helped identify and destroy 16 clandestine cocaine laboratories.

Legacy
