Murdered pensioner Una Crown's niece has appealed for help to catch her killer six months after she was found dead in her Wisbech home.
Judy Payne made the emotional plea today as detectives returned to Magazine Lane in a fresh bid for information about the 86 year old's death in January.
In a video, Mrs Payne, 69, said: "I really hope that somebody out there who knows anything, or thinks they know anything at all, comes forward to the police. Six months has now gone by and for us, it's a lifetime. We need answers.
She had been stabbed and then set on fire in an apparent effort to disguise her injuries and destroy evidence.
She had not been seen alive since Friday, January 11, but had spoken to a friend by telephone at about 5pm on the Saturday.
Officers will be returning to Magazine Lane today to put up posters and speak to residents. Officers will also be in Market Place in the town handing out leaflets. A mobile police station will also be in the town.
A £10,000 reward is being offered by independent charity Crimestoppers for information which leads to the arrest and conviction of the killer.
Anyone with any information should call the Major Crime Unit on 101 or Crimestoppers, anonymously, on 0800 555111.
