In August 1966, two Brazilian technicians were found dead on a remote hillside, their faces covered with strange lead masks. There were no signs of struggle, no clear cause of death—and beside them lay a cryptic note that read: “Await signal.” Who were these men? What were they doing on Vintem Hill? And what deadly ritual were they attempting before they died? In this full-length documentary, we explore the baffling case of Manoel Pereira da Cruz and Miguel José Viana, uncovering the details of the police investigation, the mysterious note, and the strange theories that have haunted Brazil for nearly sixty years. From Spiritist rituals to UFO contact experiments, this is one of the strangest true mysteries ever recorded. Late into the edit I found this extremely detailed write up of the case, that seems to follow the Brazilian reports. I can't vouch for how accurate it is, but it adds some interesting details and creates a nice timeline of some events. As well as some factors I may have missed. - https://pmig96.wordpress.com/2021/05/10/the-lead-masks-case/ Support the channel with Patreon - www.patreon.com/thetapelibrary Do you have a supernatural story to share?
