Griffiths admitted murdering three prostitutes in the town of Bradford and was sentenced to life in prison in 2010. Sutcliffe, who was known as the Yorkshire Ripper, was sentenced to 20 life sentences in 1981 for murdering 13 women and he pleaded guilty to 7 counts of attempting to murder seven other women.  The majority of his victims were prostitutes. His first serious attack on a prostitute happened in 1969, but because the woman did not want to press charges he was not charged. On 16 July 2010 this sentence was extended to a full life term, meaning that Sutcliffe will not leave prison alive, barring any judicial developments to the contrary. Sutcliffe appealed this decision, but on January 14th, 2011, he lost the appeal.
