Robert Mazur tells the full story of his time as a government agent investigating drug-money laundering. Mazur went undercover for the US Drug Enforcement Administration, the Internal Revenue Service intelligence division, and the Customs Service.
In Operation C-Chase, Mazur successfully infiltrated the Medellín cartel by posing as a wealthy, mob-connected businessman named Robert Musella. He established connections with Pablo Escobar's lawyer Gonzalo Mora and Escobar's trafficker Roberto Alcaino. At the height of its power, the cartel is estimated to have supplied over 80% of all cocaine shipped to the US, around 15 tons a day.
