Serial killer and cult leader Adolfo Constanzo, between 1986 and 1989, led the drug-trafficking and occult sacrifice gang that came to be known as either the Matamoros Cult or the Narco-Satanists. Along with his companion and self-professed witch Sara Aldrete, the cult was responsible for the torture and murder of at least fifteen people, and possibly dozens more. Their most infamous crime was the horrifying torture and murder of American pre-med student Mark Kilroy, who was abducted while in Mexico for spring break. Join Tom and Jenny on this gruesome descent into black magic and butchery on a stomach-churning episode 390.
