http://www.bbc.co.uk/news/uk-england-lancashire-12396506 Joan Harrison, 26, who was found dead in a derelict garage in Preston in 1975, was once thought to have been killed by the Yorkshire Ripper. But detectives said DNA found at the scene matched that of Christopher Smith from Leeds, who died in 2008 aged 60. Smith had a DNA swab taken when he was arrested for drink driving in 2008, but he died six days later from a terminal illness. 'Put record straight' Investigations have revealed he had criminal convictions ranging from assault and theft to sex attacks.
Good to see this case is closed but unfortunately they did not catch him in time partly due to the less advanced type of DNA testing at that time but mainly due to that idiot who kept sending letters claiming to be the Yorkshire ripper in which he claimed to have done this murder. Fortunately they caught him but should have doubled the number of years he spent in prison.
