Peter Sutcliffe is an infamous English serial killer, who was also known as the ‘Yorkshire Ripper.’ He was convicted for the murder of 13 prostitutes and attempt to kill seven more women. Born and raised in Yorkshire, England, he had mental troubles since childhood. Before his marriage, he would hire a lot of prostitutes and, according to his friends, he was conned by some of them very badly, which led to his hatred toward them. He committed his first murder in 1975 and continued for the next five years, until he was finally tracked down by the police in January 1981. Following this, he received 20 life sentences, which meant that he would be spending the rest of his life in jail. Soon after his prison sentence began, he showed signs of mental illness and was found to be suffering from schizophrenia. He was sent to a psychiatric unit for treatment and was then sent back to prison.
