Sister of murdered Anne Dunwell appeals to end '50-year nightmare'
The sister of a murdered school girl has appealed for information to "see the killer brought to justice" and end a "50-year nightmare".
Anne Dunwell, 13, was sexually assaulted, strangled and left naked at the foot of a manure heap in Maltby, Rotherham, on 6 May 1964.
The killer has never been identified and it remains South Yorkshire's oldest unsolved murder case.
Irene Hall, 68, believes "somebody does know" what happened to her sister.
"You learn to live with the pain and heartache but it never goes away," Mrs Hall said.
"I appeal to those who, for their own reasons, have kept information to themselves for so long.
"It is possible that the person responsible may now be dead but did they admit what they had done?"
'Never be forgotten'
Anne had been visiting her aunt in Bramley that day, and disappeared while on her way home to Whiston.
Her body was found the next day.
A post-mortem examination revealed the teenager had been strangled with her own stockings.
Det Supt Richard Fewkes, of South Yorkshire Police, said: "The case has been reviewed on a number of occasions in the past and new lines of inquiry identified.
"Sadly these did not lead to the identification of Anne's killer."
But he said the murder "should never be forgotten".
Mrs Hall added: "My father always wanted to know who could do such a thing before he passed away, but he never got to know.
"I'd like to see the killer brought to justice too, but I'm not getting any younger. If I don't then the burden will fall to my children."
