As the leader of a cult that drove Matamoros, Mexico, into a frenzy of ritualistic executions and drug-fueled violence in the 1980s, Sara María Aldrete, who was born in Mexico in 1964, rose to fame and became a notorious figure. Known as "La Madrina" or "The Godmother," Aldrete was a charming and manipulative woman who took advantage of the weaknesses and beliefs of her followers in order to take control over them.

Aldrete's cult, which was also referred to as "Los Narcosatánicos" or "The Narcosatanists," founded by Adolfo Constanzo who initiated Aldrete, combined aspects of drug trafficking with bizarre rituals that were inspired by a perverted understanding of satanic beliefs. As a result of her influence, the cult participated in heinous activities, such as the mutilation and sacrifice of human beings, in the mistaken idea that these rites would bestow upon them the ability to protect and control themselves.

During the spring break of 1989, an American student named Mark Kilroy was kidnapped and murdered by Aldrete and her cult. This crime was considered to be the most notorious homicide related with Aldrete and her cult. After some time had passed, the body of Kilroy was discovered in a shallow grave. He had been the victim of a ritualistic killing that was an attempt to bring the cult supernatural abilities.

Their reign of terror came to an end in 1989, when Mexican authorities, acting on a tip, invaded the compound of the cult and arrested its members. The fate of Sara María Aldrete continues to serve as a disturbing reminder of the perils associated with radical ideas and the influence that may be exerted through deception. Because of the destructive propensity of individuals who seek to exploit others for their personal benefit, regardless of the cost in human lives.
