Adolfo de Jesús Constanzo was an Cuban American serial killer, drug dealer, and cult leader of an infamous gang that was dubbed The Narcosatanists (Spanish: "Los Narcosatánicos") by the media. His cult members nicknamed him The Godfather ("El Padrino"). He led the cult with Sara Aldrete, whom their followers nicknamed "The Godmother" ("La Madrina"). The cult was involved in multiple ritualistic killings in Matamoros, Tamaulipas, Mexico, including the murder of Mark Kilroy, an American student killed in Matamoros in 1989.
Constanzo fled to Mexico City with four of his followers. They were only discovered when police were called to the apartment because of an unrelated dispute taking place there. As the officers approached, Constanzo, mistakenly believing they had located him, opened fire with a machine gun. This brought in police reinforcements. Determined not to go to prison, he handed the gun to follower Álvaro de León and ordered him to open fire on him and Martín Quintana. By the time police reached the apartment, both Constanzo and Quintana were dead. De León, known as "El Duby", and Sara Aldrete were immediately arrested.
