Biography
Edgar Maury Santiago was a Puerto Rican independence supporter jailed for refusing federal grand-jury questions in an investigation of stolen explosives. He challenged the immunity procedure, alleged electronic surveillance and requested protection against translation errors in English-language proceedings. Torres Maldonado’s source-cited history reports that he was sent to the penal camp at Sabana Hoyos, Arecibo, in April 1976 and actually spent five days imprisoned before the grand jury expired. The six-month contempt term described by the source was not six months actually served. The exact admission and release days remain unknown.
