Michael Briere raped and murdered 10-year-old Holly Jones because he was consumed with desire after looking at child pornography. Paul Bernardo was driven by deviant fantasies of torturing women. He murdered teenagers Kristen French and Leslie Mahaffy and raped dozens of other women. Selva Subbiah drugged and raped hundreds of women to feed his sexual perversions. Now these predators have something in common. They’re together in the same miserable cellblock of maximum-security Kingston Penitentiary that houses the lowest of the low, the sex offenders, child molesters and killers who can’t survive among their own kind.
