The Lead Masks Case: What Did They See?

August 20, 1966. Vintém Hill, Rio de Janeiro, Brazil. Two ordinary electronics technicians walk up a lonely hill during a torrential rainstorm, dressed in formal suits. Days later, they are found dead, lying side-by-side in the tall grass with no signs of violence. But the mystery that shocked world-class detectives wasn't how they died—it was what was covering their faces. Both men were wearing custom, handmade heavy lead masks over their eyes. Next to them lay a cryptic notebook outlining a chilling countdown to a lethal deadline: "Swallow the capsule... wait for the mask signal." Did they successfully use radio frequencies to contact an extraterrestrial spacecraft, only to be consumed by its blinding radiation? Or were they victims of a cold-blooded spiritual scam?
