Nora Sheehan, a 54-year old woman from Innishannon, Co Cork, was discovered by forestry workers in Shippool Wood, Innishannon in June 1981.
A Serious Crime Review investigator disclosed that there is real “potential” to progress the investigation into the death of the mother of three.
Ms Sheehan had been missing for almost a week when she was found. She was last seen when she attended Cork’s South Infirmary Hospital for treatment for a dog bite to her arm.
Over the last few years, the Serious Crime Review team has been investigating more than a dozen cases including Garda Dick Fallon, Eileen Costello, Séamus Doherty, Felix McCann, Dessie Fox, Patrick Heeran, Irene White, Deirdre Jacob, and Charles Brooke Pickard.
The disappearance of 18-year-old Deirdre Jacob outside her Newbridge, Co Kildare, home in 1998 is the latest case completed by the Serious Crime team.
Gardaí in Co Kildare are now planning to implement recommendations from the Serious Crime Unit which includes re-interviewing witnesses.
Deirdre was to start her second year of teacher training at St Mary’s in Strawberry Hill, Twickenham, and was getting a bank draft to send to a college friend for her rent deposit.
She went to the bank, the post office and then visited her granny in her shop before heading home. She was last seen shortly after 3pm inside the gate of the family home in Roseberry, Newbridge.
Her father, Michael Jacob, said: “Every day we have memories and thoughts. We are all the time waiting for a phonecall. We are convinced someone, somewhere has information.”
