Roger Wilkes, a BBC news editor, investigated the case for a radio programme to be broadcast on the 50th anniversary of the crime in early 1981. Wilkes learned that Goodman's suspect, a man named Richard Gordon Parry, had given the police an alibi for the time of Julia's murder a woman to whom he was engaged. However, after Wallace's death and after being jilted by the suspect, the woman offered to swear to Wallace's solicitor that the alibi had been false. Wilkes also discovered that, on the night of the murder, Parry had visited a local garage where he had used a high-pressure hose to wash down his car. A mechanic at the garage had noticed that one of his gloves was soaked in blood. Wilkes attempted to track down Parry, only to learn that he had died but a few months previously.
