Once one of the top kingpins in the U.S. for Mexico’s Sinaloa cartel, he is starting a second career—teaching law-enforcement officers how to catch drug traffickers.
Slight of build, with short cropped hair, Flores darted back and forth at the front of a stage.
About 30 law-enforcement agents from Montana and nearby states leaned in and listened intently.
