While the names of those in civil confinement are often shielded, a comparison of records showed the 77 predators shared one of two addresses — both of which happened to be upstate mental hospitals that house the civilly confined. One of the predators is Hector Aviles, 61, who was known as the “voodoo rapist.” Aviles was convicted of second-degree rape in Westchester County in 2008 after telling three of his victims — the oldest of whom was 16 — that if they participated in a sexual “ritual” with him, he could help them with their problems. If they didn’t, he said, bad things would happen to them and their families.
