Two Men Found Dead Wearing Lead Masks – The Mystery That Still Terrifies Brazil

In August 1966, police in Niterói, Brazil, discovered one of the most baffling and eerie scenes in modern history. Two men were found dead on a remote hillside, dressed in matching formal suits, raincoats, and strange lead masks covering their eyes — the kind used to protect against radiation. Beside them lay an empty water bottle, two towels, and a cryptic note that read: “Be at the specified place at 4:30 PM. Swallow capsules. After effect, protect metals, wait for signal.” There were no signs of violence, struggle, or poison detected in their systems. The men were later identified as electronic technicians from Rio de Janeiro who had reportedly been interested in spiritualism, UFOs, and the paranormal. To this day, no one knows what the “signal” was, what the capsules contained, or what caused their deaths. The case remains one of Brazil’s most chilling unsolved mysteries — a haunting mix of science, ritual, and the unknown.
