Borromeo was born in Chiapas, Mexico, to a wealthy Mestizo family. Borromeo was involved with law as a young man and headed to Harvard University in the United States for law training. He stayed in the USA and moved to Miami for a new contract, sent by Don Rico Granados of the Granados crime family. Borromeo was involved with the family's drug dealing and other illicit activities, which he all advised.
In the war with the Corleone crime family in 1959, he was a target for them. After one year, Capo Dominic was able to take over all of Granados' fronts and Borromeo was killed when Dominic attacked the Granados Compound, where the Corleones finished off the last Granados enforcers and made men.
