For three decades, Hipolito Acosta’s work routinely made national headlines, and he quickly gained a reputation as a daring crime fighter who used his intelligence and audacity to stay one step ahead of those who would kill him if his cover were ever blown. He had himself smuggled from Mexico to Chicago with a truckload of poor immigrants; worked his way into the confidences of a gang of international counterfeiters; socialized with some of Mexico’s most vicious drug lords; arrested a female smuggler by luring her across the U.S. border for an amorous rendezvous; and was the target of multiple murder plots by the criminals he put in jail.
