COUNTY JUDGE'S RACE HEATS UP: WAS GUERRA INVOLVED IN HUACHICOL?

Huachicol, in the context of beverages, refers to an adulterated alcoholic drink, often made with low-grade alcohol, though the term is now more famously associated with the illegal siphoning and theft of fuel (gasoline/diesel) in Mexico, a practice carried out by "huachicoleros". While the original beverage meaning is rooted in traditional, sometimes illicit, alcohol mixing, the modern usage primarily describes the criminal activity of stealing and selling stolen fuel, sometimes through sophisticated tax evasion schemes known as "huachicol fiscal." 

A U.S. advisory in May called huachicol schemes “the most significant non-drug illicit revenue source” for Mexico's cartels, which have become a prominent Trump administration target. But the cartels often rely on affiliated individuals and firms—including along the Texas border—to pull them off.
