A 92-year-old man has been charged with murder and rape following the death of 75-year-old Louisa Dunne in Bristol in 1967, Avon and Somerset Police said.
Ryland Headley was charged overnight by detectives and has been remanded into custody to appear at Bristol Crown Court on Thursday.
Ms Dunne’s body was discovered by a neighbour inside her home in the Easton area of Bristol in June 1967, almost six decades ago.
Her cause of death was recorded as strangulation and asphyxiation.
Headley, who was accompanied by his solicitor, was not asked to enter pleas to the two charges against him.
He spoke only to confirm his name, date of birth and address, and that he understood the hearing was taking place as if he was physically present in court.
Detective Inspector Dave Marchant said: “This development marks a hugely significant moment in this investigation.
“Now criminal proceedings are under way it’s important to stress the defendant has the right to a fair trial.
“Any speculation or misinformation on the circumstances of this case has the potential to prejudice these ongoing proceedings.
“We’ve updated Louisa’s family about this charging decision and a specialist liaison officer will continue to support them in the coming days, weeks and months.”
