Nina Gill, the granddaughter of murder victim Sharif Demirsay, says the reward is designed to help get justice for her granddad.
Bedfordshire Police have offered a £10,000 reward in the hunt for the killers of a Kempston pensioner.

Mr Demirsay's 68-year-old partner was hurt as she tried to fight off the men who had got into their home in Vineyard Way on May 14 this year.
They stabbed him multiple times. As he lay dying in the hallway the attackers demanded money and jewellery form his partner, who was also stabbed and needed surgery.
£1,000 cash and gold jewellery was taken.
Police are still searching for the murder weapons - believed to be kitchen knives - that could have been discarded in hedgerows or gardens by the killers as they left the scene.
