Cold case detectives are making a fresh appeal to find the killer of a Mytholmroyd pensioner on the 25th anniversary of her murder.
Agnes Ogden, 88, was found dead at her home in Erringden Road on the morning of 19th December 1991 by health authority staff.
She had suffered a blow to the face and had been asphyxiated and was discovered in her downstairs bedroom.
Detectives have said they believe someone in the local area will know the identity of her killer and it is time for that person to come forward.
Previous forensic reviews have been conducted into the case by homicide detectives and it is hoped that as technology improves and more work is conducted that fresh clues may be unearthed.
It is not clear whether anything was stolen from her house, and no motive has ever been established for the attack.
Detective Superintendent Jim Dunkerley of the Major Investigation Review Team, said:
"Mrs Ogden was a much loved and respected local woman who was the victim of a savage attack in her own home.
"We have never closed this case and are now conducting a review to try and determine what happened and who was responsible for a death which rightly shocked residents across West Yorkshire at the time.
25 years have now passed since Agnes’s murder and I strongly believe the answer to who murdered her remains in the local area.
