We know many things about the 1981 triple murder of Fred Alvarez, Patricia Castro and Ralph Boger. We know that the bagman for the hit, Jimmy Hughes, confessed. We know that a 2010 trial was interrupted when charges were abruptly dropped and evidence lost. We know from witness statements that the murders appear to be connected to the corruption surrounding Wackenhut and the PROMIS affair. We know from FBI’s own records that the Bureau looked into the matter. And most recently, we know that the FBI has not only repeatedly refused to release those files, but apparently removed the request from their FOIA tracking system.
