Almost 60 years later, 80 year old career criminal Henry (Harry) James Burge claimed to have committed the theft, confessing to a newspaper, with the story being published in the Sunday Pictorial newspaper on 23 February 1958. He claimed to have carried out the robbery with two other men, although when discrepancies with a contemporaneous report in the Birmingham Post newspaper (the crime pre-dated written police reports) in his account of the means of entry and other items stolen, detectives decided there was no realistic possibility of a conviction and the case was closed. Burge claimed the cup had been melted down to make counterfeit half-crown coins, which matched known intelligence of the time, in which stolen silver was being used to forge coins which were then laundered through betting shops at a local racecourse, although Burge had no past history of forgery in a record of 42 previous convictions for which he had spent 42 years in prison. He had been further imprisoned in 1957 for seven years for theft from cars. Released in 1961, he died in 1964.
