Reward over death of Risbury pensioner Albert Ryall
West Mercia Police are offering a £10,000 reward for information about the death of a Herefordshire pensioner.
Albert Ryall, 75, was found dead on 13 November 2000 after a break-in at The Hop Pole Inn, a former pub, in the village of Risbury.
A team of 20 detectives are now reviewing the case in the hope of finding out who was responsible.
Det Ch Insp Andy Hughes said: "Until we find out the truth this investigation will not go away."
"It's absolutely clear to me that Albert's death was as a result of a criminal incident, his heart attack was clearly brought on by that incident."
An inquest in 2002 found Mr Ryall was a victim of unlawful killing.
Seven people were arrested as part of the original investigation but no-one was charged.
Mr Hughes said: "I wish to either implicate or eliminate them [those arrested] as part of this investigation. I'm absolutely sure that there are a number of people in the community that know what happened to Albert Ryall.
"I'm appealing for those individuals to come forward and provide information in the strictest of confidence."
The police believe advances in forensic technology could help drive the case forward.
"The emotions suffered by the family are as raw today as they were 10 years ago and I'm determined to work as hard as I can, and my team the same, to ensure we establish the truth," Mr Hughes said.
