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 is serving a life sentence in prison. 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. Operation Pisces. In 1986, Diaz was one of the principal undercover agents in Operation Pisces, an international operation involving Colombia and Panama.

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.
