Wikipedia overview indexed “Lead Masks case” in connection with the public record around Lead Masks case, a 1966 UFO/UAP dossier centered on Niteroi, Rio de Janeiro, Brazil. The source is useful because it fixes a checkable part of the record: who published the material, what topic it addressed, and how it connects to the timeline, witness layer, official response or later research around the case.
The accessible source text states: The lead masks case involves a series of events which led to the death of two Brazilian electronics technicians, Manoel Pereira da Cruz and Miguel José Viana, who had last been seen by their families on August 17, 1966. Their bodies were discovered on August 20, 1966, and the cause of their deaths has never been determined. In the archive context, that material is treated as a primary or secondary record to be compared with the case chronology rather than as a standalone proof of an extraordinary origin.
For Lead Masks case, the relevant evidence categories include bodies, notes, lead masks. The source should therefore be read alongside the dossier's witness accounts, timeline, evidence analysis and skeptical notes, especially where the material concerns official statements, video records, archival summaries or media reports.
The evidence boundary remains important. A source page can document that a report, document, video or database entry exists, but it does not by itself establish that the object or event was anomalous. This local record preserves the source's role in the case while keeping unresolved claims separate from confirmed facts. Original source URL: https://en.wikipedia.org/wiki/Lead_masks_case
