 The sister of Francisco Rafael's mother, Agustina Félix Zazueta, married Jesús Labra Avilés (alias "El Chuy"), a drug trafficker under the tutelage of Miguel Ángel Félix Gallardo, the former leader of the Guadalajara Cartel and a high-profile drug lord in Mexico.Other sources say that the Arellano Félix brothers were nephews of the drug lord Félix Gallardo, who allegedly introduced them to the drug trade in Baja California.Benjamín worked with the drug trafficker Javier Caro Payán (cousin of Rafael Caro Quintero), who later fled to Canada after Félix Gallardo was arrested in 1989 and after he feared a coup from the Arellano Félix.
