Ismael “Mayo” Zambada García, 76 years old, originally from Culiacán, Sinaloa, will finally be prosecuted by U.S. authorities for drug production. He was arrested by the DEA a couple of weeks ago. Some say it happened in Mexico, others say it was in the U.S. The fact is that his arrest represents a significant blow that shakes the stability of Mexican cartels and their drug production, including the opioid fentanyl, which kills 200 people every day in the United States, where 442 million doses of fentanyl were seized in the last five months.
