A reconstruction of the 86-year-old’s last-known movements will be shown on the programme which will be aired on BBC1 at 9pm tonight (Monday).

It will include an interview with Mrs Crown’s niece and nephew, John and Judy Payne.

Mrs Crown’s 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.

Detective Inspector David Grierson said: “We hope the Crimewatch appeal will help us get that vital piece of information to help bring whoever is responsible for Una Crown’s murder to justice.

“She was a small lady who posed no threat to anyone – hopefully the reconstruction will show that and encourage anyone with information 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.

A 58-year-old man remains on bail until May 15.

Anyone with any information should call the Major Crime Unit on 101 or Crimestoppers, anonymously, on 0800 555111.
