A reward of £10,000 is still available for helping detectives to track down a South Yorkshire killer.
The crime-fighting charity Crimestoppers put up the reward last May in the hope that it would tempt those with vital information about the death of 80-year-old Tommy Ward to come forward.
Mr Ward was attacked in a robbery in his home in Salisbury Road, Maltby, Rotherham, in October 2015.
His £30,000 life savings, which he kept in a safe, were stolen in the raid.
An identical safe was found dumped in the canal in Kilnhurst, Rotherham, two weeks later.
Mr Ward died from his injuries in February 2016 and a murder probe was launched.
An appeal for information will be made tonight on the BBC's Crimewatch programme.
The Crimestopper's cash reward is for information leading to the arrest and conviction of the killer.
Detective Chief Inspector Vicky Short described the attack on Mr Ward as 'nasty and brutal'.
Anyone with information should call South Yorkshire Police on 101.
