Dr. Park Dietz, who works with us frequently, has stated, “None of the serial killers that I’ve had the occasion to study or examine has been legally insane, but none has been normal, either. They’ve all been people who’ve got mental disorders. But despite their mental disorders, which have to do with their sexual interests and their character, they’ve been people who knew what they were doing, knew what they were doing was wrong, but chose to do it anyway.”
