premise: A man who spent 27 years in jail for the murder of a barmaid in Southampton had his conviction quashed at the Court of Appeal today after DNA tests proved that he could not have been the killer. Sean Hodgson, 57, was found guilty in 1982 of killing Teresa de Simone, 22, who was found strangled in her Ford Escort three years earlier in a car park below the pub where she worked part-time. He has long pleaded his innocence after retracting a confession initially given to a Roman Catholic prison chaplain - one of hundreds of crimes to which he pleaded guilty because, as he told his original trial, he was a "pathological liar".
hypothesis: Sean Hodgson was in jail for 22 years.
