A psychopathic sex offender has been set free again in British Columbia, after being briefly detained, despite the revelation that he was “harassing a vulnerable female” near the halfway house where he’s under supervision and other troubling discoveries. Authorities expressed “significant concern” after learning that Donald Gazley (inset) secretly struck up a pen-pal relationship with a female sex offender in a U.S. prison – a woman who helped a man abuse her daughters. Gazley has a three-decades long criminal record that includes sex crimes against children and vulnerable adults and a conviction for involvement in a murder. He appears to be a rare and particularly dangerous offender – a sexual psychopath who preys on children and adults, male and female. Most offenders like him resist treatment and never stop committing crimes.
