López Serrano, alias ‘El Mini Lic’ and 34 years old, is so far the highest-level drug trafficker to turn himself in to US authorities. He did it in July 2017 at the border checkpoint in Calexico, California, to escape the persecution of the children of his godfather ‘El Chapo’. Two months before his father Damaso Lopez Nunez cartel financial operator, had been captured in Mexico.
