Peter Sutcliffe, also known as the Yorkshire Ripper, said his life was 'torment beyond belief’ in a never-seen-before letter. He's infamous for murdering 13 women in a killing spree between 1975 and 1980. He was found guilty of all 13 counts of murder and was handed 20 concurrent life sentences. A newly emerged letter has offered some rare insight into the state of mind of the murderer during his time in Broadmoor Hospital. | Metro
