Terrifying & True | The Lead Masks Case: Brazil’s Unsolved UFO Death Mystery

Author: Henrique Couto | Scary Stories & Horror Expert April 13, 2026 Duration: 31:45
The Lead Masks Case is one of the strangest unsolved mysteries in true crime history: two Brazilian electronics technicians, found dead on a hillside in Niterói, Brazil, wearing homemade lead eye masks, with a cryptic note instructing them to take capsules, await a signal, and use the mask afterward. In this episode of Terrifying & True, we dig into the eerie facts, the failed investigation, the missing cause of death, and the theories that have kept this bizarre case alive for decades—from UFO encounters and occult experiments to poison, fraud, and murder. 

This is the kind of case that feels too strange to be real: raincoats in the brush, missing money, removed watches, a note that reads like a ritual checklist, and no clear answer for what killed Miguel José Viana and Manoel Pereira da Cruz. The deeper you go, the weirder it gets. If you love unsolved mysteries, paranormal true crime, UFO cases, bizarre deaths, Brazilian mysteries, and strange historical cases, this episode is built to pull you all the way in. 

Inside this episode:
  • The 1966 deaths of two technicians on Morro do Vintém
  • The infamous lead masks and the chilling note
  • Capsules, signals, and “protect metals”
  • Witness claims, missing money, and possible companions
  • The autopsy delay that doomed the case
  • Why the official cause of death remains unknown
  • Theories involving UFOs, spiritualism, poison, and homicide

If you’ve ever been fascinated by cases where the evidence seems to point everywhere and nowhere at once, The Lead Masks Case is an all-timer. It is eerie, unresolved, deeply atmospheric, and still haunting more than half a century later.

We’re telling that story tonight.
