inputs: hypothesis: Sean Hodgson was convicted of the murder of Teresa De Simone. premise: A man who spent 27 years in jail for a murder he did not commit finally had his conviction overturned today after DNA tests destroyed the prosecution case against him. But even as Sean Hodgson, a frail 57-year-old, celebrated his freedom on the steps of the Royal Courts of Justice, it emerged that the DNA tests which freed him should have been carried out 11 years ago. Mr Hodgson was found guilty in 1982 of killing Teresa De Simone, 22, who had been found strangled in her Ford Escort three years earlier in a car park below the Southampton pub where she was a part-time barmaid.
