“I have no interest in parole and no plans to seek release,” David Berkowitz, the convicted “Son of Sam” serial killer, tells Fox News in a new letter. Berkowitz claims he is “already a ‘free man’” because he has found Jesus Christ. “I am not saying this jokingly,” he assures. “I really am.” But he’s really not: Berkowitz, 58, is serving six consecutive sentences of 25 years to life for murdering six people and injuring seven others. He has been denied parole five times previously in 34 years of incarceration. “I’m a hyperactive, always ‘on the go’ type person,” writes Berkowitz. “But I’ve often been told that I do not take enough time for myself.” Presumably it is easier behind bars.
