Antônio Vilas-Boas’s reported abduction

Witness account

Vilas-Boas said that while working at night he was seized by beings, taken aboard a craft, medically examined and subjected to a sexual encounter with a female-presenting being. He described the experience as frightening and coercive. The account is chronologically earlier than the Hills’ alleged event, but its history of recording and publication must be dated separately.

Public record

A deposition dated 22 February 1958 and later published investigator accounts preserve the narrative. Flying Saucer Review presented versions in 1965 and a fuller account in 1966. Reports about physical symptoms derive from the case’s medical and investigator descriptions, not a demonstrated extraterrestrial cause.
