Adolfo Constanzo

On March 1, 2018, the ID Channel series Pandora’s Box: Unleasing Evil portrayed the crimes in an episode entitled "The Devil’s Ranch".

On July 13, 2013, the Investigation Discovery Channel profiled this crime in its Poisoned Passions series. The episode is titled "Sacrificial Evil." Constanzo was portrayed by actor Aldo Uribe.

Constanzo was also profiled in the documentary Instinto Asesino, which aired on Discovery en Español in 2010. The episode was entitled "El Padrino".

Constanzo started to raid graveyards for human bones to put in his nganga, or cauldron. Before long, his cult decided that the spirits of the dead that resides in the nganga would be stronger (providing the cult more powerful protection) with live human sacrifices instead of old bones. The killings soon totaled more than 20 victims, whose mutilated bodies were found in and around Mexico City. This process escalated until Constanzo eventually decided that the nganga needed the power of a brain from an American student, culminating with the 1989 murder of Mark Kilroy.

On March 13, 1989, Constanzo's henchmen abducted a pre-med student, Mark Kilroy, from outside a Mexican bar and took him back to the ranch. Kilroy was a US citizen who had been in Mexico on spring break. When Kilroy was brought to the ranch, Constanzo murdered him. Under pressure from Texan politicians, Mexican police initially picked up four of Constanzo's followers, including two of the Hernandez brothers. Police quickly discovered the cult and that Constanzo had been responsible for Kilroy's death; he sought a "good"/superior brain for one of his ritual spells. Officers raided the ranch and discovered Constanzo's cauldron, which contained various items such as a dead black cat and a human brain. Fifteen mutilated corpses were dug up at the ranch, one of them Kilroy's. Officials said Kilroy was killed by Constanzo with a machete chop to the back of the neck when Kilroy tried to escape about 12 hours after being taken to the ranch.

In 1988, Constanzo moved to Rancho Santa Elena, a house in the desert. It is there where he carried out more sadistic ritual murders, sometimes of strangers and other times of rival drug dealers. He also used the ranch to store huge shipments of cocaine and marijuana.

Adolfo de Jesús Constanzo (November 1, 1962 – May 6, 1989) 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 was born in Miami, Florida to Delia Aurora González, a Cuban immigrant mother in 1962. She gave birth to Adolfo at the age of 15 and eventually had three children, by different fathers. She moved to San Juan, Puerto Rico, after her first husband died, and remarried there. Constanzo was baptized Catholic and served as an altar boy, but he also accompanied his mother on trips to Haiti to learn about Vodou. The family returned to Miami in 1972 and his stepfather died soon after, leaving the family with some money. As a teenager, Constanzo became apprenticed to a local sorcerer and began to practice a religion called Palo Mayombe, which involves animal sacrifice. His mother remarried and his new stepfather was involved in both the religion and drug dealing. Constanzo and his mother were arrested numerous times for minor crimes like theft, vandalism and shoplifting. He graduated from high school, but was expelled from prep school.
