The sister of a woman murdered in Aberdeen 40 years ago has appealed for anyone who may be able to help to come forward and speak to police.
Rita Ling made the appeal ahead of the 40th anniversary of the murder of Dr Brenda Page.
The 32-year-old geneticist was found dead in her home on Allan Street by her neighbour on Friday, July 14 1978.
The investigation into her death was reopened in 2015.
And now her sister is appealing for anyone who may be able to help police build up a picture of Brenda’s life in the days before her death to come forward.
Rita Ling said: “Forty years have passed since Brenda was found and not a day goes by when we don’t think about her and the horrendous ordeal she must have suffered that night.
“Brenda was an extremely intelligent woman with her whole life ahead of her. It pains us to think of the great things she would have undoubtedly achieved.
“It is important the Police and Crown Office have all potential information available to them to bring the person responsible for her death to court. Please come forward if you think you can help.”
Detective Inspector Gary Winter, of Police Scotland’s major investigation team, said: “I believe that there are people who lived near Brenda on Allan Street who have possibly never spoken to the police before, or at any great length.
“I don’t think there’s any untoward reason for this other than they didn’t think their information would be useful because it didn’t relate to Brenda’s death itself.
“I must stress that our enquiries don’t just focus on Friday July 14 1978 and the hours leading up to her body being found.
“It is crucial we build a picture of Brenda’s life generally as part of our inquiries which is where her neighbours, friends and colleagues come in.
“I appreciate this was a long time ago however if you do remember anything, I urge you to come forward.
“Brenda worked within the Genetics Department at the University of Aberdeen Medical School from 1973 until her murder in 1978 and would have crossed paths with many students and academics during this period of her work life.
“We have spoken to many of her former colleagues but I would appeal to any others not previously seen by the police to get in touch for the same reasons.
“If you know of anyone who might not live in this country anymore, I would ask that you share this appeal with them.”
He added: “Forensic techniques and processes have changed dramatically over the past 40 years and we continue to use every resource at our disposal to explore information relating to this case.
“It is crucial someone is brought to justice for Brenda’s murder.
“Please be assured we continue to ensure this happens.
“Anyone with information is urged to get in contact by calling 101 or by emailing SCDHOLMESAberdeen@scotland.pnn.police.uk”
