Michael Riconosciuto is an electronics and computer expert who was arrested in early 1991, shortly after providing Inslaw, Inc. with an affidavit in support of their lawsuit against the U.S. Dept. of Justice. Riconosciuto professed a defense centered on the Inslaw Affair (a legal case in which the U.S. Government was charged with illegal use of computer software). Riconosciuto claimed to have reprogrammed Inslaw's case-management program (Promis) with a secret "back-door" to allow clandestine tracking of individuals. Riconosciuto stated that he had been threatened with prosecution by a justice department official. Riconosciuto provided an Affidavit detailing threats to a House Select Committee investigating the Inslaw Affair.
Riconoscuito has demonstrated some technical and scientific talents. According to an article originally published in the Village Voice:
Riconoscuito was a gifted child: When he was just 10 years old, Michael wired his parents' neighborhood with a working private telephone system that undercut Ma Bell; in the eighth grade, he won a science fair with a model for a three-dimensional sonar system. By the time he was a teenager, he had won so many science fairs with exhibits of laser technology that he was invited to be a summer research assistant at Stanford University. Dr. Arthur Schalow [sic], a Nobel laureate, remembers him—"You don't forget a 16-year-old youngster who shows up with his own argon laser."
Riconosciuto was employed as an engineer at a mine in Maricopa, California. Hercules Properties, Ltd. had raised financing and purchased a 167-acre (0.68 km2) contaminated waste-disposal site which had once been a portion of a 1,300-acre (5.3 km2) TNT and fertilizer manufacturer known as Hercules Powder Works, and which was located along San Pablo Bay in Contra Costa County, California. ("The community of Hercules, named for the factory, is still recognized by its rusting tanks and smoke stacks.")
Riconosciuto stated in 1993 that he had knowledge of the October Surprise conspiracy allegations.
Nathan Baca's Emmy winning series "The Octopus Murders" featured documents from the archives of Michael Riconosciuto. These documents have been the subject of interest for recently reopened cold case homicide investigations.
