Here's a short documentary with Brownsville's former Deputy Sheriff George Gavito. He discusses the infamous case of cult leaders Sara Aldrete (alumni of Brownsville High School and Texas Southmost College) and Adolfo de Jesus Constanzo. Not sure why but George refers to the most famous victim of this case as "John". His actual name is Mark J. Kilroy, and it is common knowledge to people who were around during the height of this case.
If you're not familiar with the case, it deals with narcotics, Juan Benitez Ayala, brujeria, kidnapping, cannibalism, superstition, cultism, human sacrifices, a mass graveyard, etc. The documentary footage of the actual ranch is deeply fascinating. Watch the video but I must warn you that it contains some gruesome images.
A decent portion of the audience for this blog comes for the music. So I imagine a few of you probably want to hear this tale in corrido form, correct? Lucky for you, Los Suspiros de Salamanca created this cancion back in 1989. It details the story of this unforgettable event in South Texas-Northern Mexico history. The song became a hit here in South Texas according to this newspaper article. Here is "Trajedia En Matamoros".
