The man behind the operation that broke up the most important organization involved in falsified documents in the United States was a double-agent who worked for Cuba and the United States. His codename was Lázaro.
In statements to EFE, Lázaro (whose real name is Robert Kelly) described the principal goal of “Tag Operation,” which was to prove Islamic terrorists used false documents sold by a [Mexican] group, however, the operation could not be completed because there was a lack of cooperation between U.S. security agencies.
Kelly (63-years old) is writing a book titled, Non Official Cover: The History of Lázaro (Sin cobertura oficial: la historia de Lázaro), where he relates his first mission was to infiltrate the Cuban General Directorate of Intelligence (Dirección de Inteligencia de Cuba) at the end of 1999 when he created a web page called La Voz de Cuba to defend the return of Elián González to his father.
He also asserts in his book that he was involved in the sale of SAM missiles in Nicaragua and in the defection of a Cuban scientist to the United States.
