Judy Payne made the emotional plea today (Thursday) as detectives returned to Magazine Lane, Wisbech, in a fresh bid for information about the 86-year-olds 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, its a lifetime. We need answers. Its important that they catch somebody as they could be out there and do it to somebody else and that is the last thing we would ever want. We wouldnt want anybody to go through what we have been through. Mrs Crowns body was discovered in her bungalow in Magazine Lane on January 13. 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 (Thursday) 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. Detective Inspector David Grierson said: It is six months since this terrible crime where Mrs Crown was murdered in her own home. We have a dedicated team still working on the investigation but are urging people to come forward if they have any information which could help us catch her killer. We believe the answer lies in the local community and we need their help. We want to hear from anyone who was in the area of Magazine Lane over that weekend in January. Did you see anything suspicious? Do you know a friend or loved one who came home acting strangely, smelling of smoke or had clothing that was burned or had blood on it? We still havent located a murder weapon, most likely a long knife, Mrs Crowns wedding ring and her front door key. Again, if anyone has come across any of those items we would urge them to call police. A £10,000 reward is being offered by independent charity Crimestoppers for information which leads to the arrest and conviction of the killer. INFORMATION: Anyone with any information should call the Major Crime Unit on 101 or Crimestoppers, anonymously, on 0800 555111.
