First photo of Charles Manson in three years California's Department of Corrections released the two photographs, which show Manson, now 77, with long, flowing grey hair and a long grey beard. Prison photographs are taken when prisoners are either transferred or their appearance changes - in Manson's case, his hair was shaved in the last photo. "He looks a lot different," Terry Thornton, a department of corrections spokesman, told CNN, who obtained the photos. Manson is due a parole hearing on April 11. He has spent the last 40 years in prison after he was jailed for brainwashing members of his commune known as The Manson Family into butchering eight people in August 1969. Among those killed was Sharon Tate, the eight months pregnant wife of film director Roman Polanski. He was jailed in 1971. Last April he broke a 20-year silence to warn the world of an impending apocalypse due to global warming. "Everyone's God and if we don't wake up to that there's going to be no weather because our polar caps are melting because we're doing bad things to the atmosphere," he said. The automobiles and fossil fuels are destroying the atmosphere and we won't have air to breathe. He also described President Barack Obama as a "slave of Wall Street." Five members of "The Family," four of them women, were found guilty for carrying out the murders and Manson - who was not present at the scenes of the crime - for being the ringleader.
