In this episode, retired agent Ed Mireles reviews true stories from his 15-plus years of undercover work using the alias Lalo. He recounts his assignments posing as a notorious drug trafficker, transporter, and money launderer who plied his trade in Miami, El Paso, Tucson, and other areas along the Southwest border between Mexico and the United States.
Lalo managed several warehouses in Miami, Florida, and he expanded to manage a transportation business and later a trucking company. The quantity of drugs he reportedly moved made him highly sought-after by the cartels and law enforcement.
Ed and his wife, Elizabeth “Liz” Mireles, who is also a retired FBI agent, are the authors of LALO, Undercover Tales of Money, Drugs and Lies, a narrative crime book based on the true stories of Ed’s undercover roles.
During his time undercover, his alter-ego Lalo was a top target of American law enforcement, referenced in Federal Bureau of Investigation (FBI) and Drug Enforcement Administration (DEA) databases as an up-and-coming player in the cartel drug world. In reality, Lalo was a law-abiding citizen, husband, and father, a U.S. Marine Corps veteran, and a decorated FBI agent. Very few people—even most “Feds”—knew that Lalo and Ed were, in fact, the same person.
“Quantico was very good for me after I was shot. I was there for three years, and that was a combination of convalescence, that allowed me to heal physically and mentally. And then, once I was officially released back on full duty, I requested to be transferred back to Miami and to a drug squad. All the undercover work that I did wasn’t public knowledge. And I did that for 15 years, and I got to be very good at it. You talked about my injury, what a perfect cover. My arm at the time, you know, my injury was fresh, was all bent and swollen and gnarly, and I couldn’t bend my fingers into a fist. So whenever I went to meet people, I mean, they looked and said, oh, who is this guy with this claw hand?”—Retired Agent Ed Mireles
