Ten years after an 86-year-old woman was stabbed to death in her home police are launching a fresh appeal to find her killer.

Detectives are re-appealing for information in connection with the unsolved murder of Wisbech pensioner Una Crown.

Police were called after family members and a neighbour discovered the body of Mrs Crown in her bungalow in Magazine Lane on Sunday, January 13 in 2013.

She had not been seen alive since Friday, January 11, but had spoken to a friend over the phone at about 5pm on the Saturday - the day before her body was discovered by police. 

The death was initially treated as unexplained but following a post-mortem examination it was concluded that Mrs Crown died from stab wounds to her neck and chest and a murder investigation was launched. 

Mrs Crown's clothing had also been set alight, in an apparent attempt to disguise her injuries and destroy evidence.

But the fire did not spread to the rest of the house and self-extinguished.

Detective chief inspector Iain Moor, from the Bedfordshire, Cambridgeshire and Hertfordshire major crime unit, said: "Ten years on from this tragic case, Mrs Crown’s murderer remains undetected and we have not been able to get justice for her family. 

"We continue to seek opportunities for new lines of inquiry and on the tenth anniversary of the tragic events, I wanted to re-appeal to the public. 

"We still believe the answer to solving this case lies within the local community.

"I am urging anyone who has information but not yet come forward, to do the right thing and get in touch – someone out there knows what happened to Mrs Crown. 

"Any information, no matter how small or insignificant it may seem, may be key to solving this investigation."

Anyone with information should report to police online quoting Operation Valyrian, use the web chat service or call 101.
