Rico was an FBI agent in Boston who knew a young Bulger and Stephen Flemmi, and their relationship is considered to be the beginning of the corrupt nexus of law enforcement and Bulger's underworld.
Later, Rico left the bureau and began working as head of security at World Jai Alai.
There, he was reconnected with Flemmi and Bulger, who allegedly skimmed money from the company. He was accused of complicity in the murder of Roger Wheeler, a World Jai Alia executive who discovered that gang members were skimming of the top.
Rico died in custody in 2004 before going to trial.
