 In Spanish folklore, the "Sacamantecas" (Spanish for "Fat Extractor") is a bogeyman-type character, often conflated with the child-targeting sack man, that abducts people to extract their body fat and sell it.Juan Díaz de Garayo was called "The" Sacamantecas upon his arrest and conviction, and today is sometimes referred to as "the real" Sacamantecas, but he wasn't the origin of this legendary character, as it predates him, nor did he ever extract the body fat of his victims.The idea that the murders were the work of a Sacamantecas was actually a popular rumor that began prior to Garayo's arrest, when there was no known culprit.
