Premise: Rafael Caro Quintero (born October 3, 1952) is a Mexican drug trafficker who founded the now-disintegrated Guadalajara Cartel with Miguel Ángel Félix Gallardo and other drug traffickers in the 1970s. He is the brother of fellow drug trafficker Miguel Caro Quintero, the founder and former leader of the extinct Sonora Cartel who remains incarcerated.
Hypothesis: Rafael was at least 20 years old when he was still in the drug trafficking business
