In 2014, the capture of drug kingpin “El Chapo” made headlines. Instrumental to that capture was two of El Chapo’s own men—Junior and Peter Flores—twin brothers originally from Chicago. After a cartel war broke out in Mexico, the brothers decided to become informants to protect their families. Now, their wives, Mia and Olivia, tell all in their new book “Cartel Wives” about what it was like to be married to two of the world’s biggest drug dealers.
