The remains of a woman whose body was exhumed by cold case officers have been reinterred.
A post mortem has been carried out on Margaret 'Margot' Seery, who was exhumed from a grave in Rathkeale, Co Limerick, this morning.
Her remains were reinterred this evening and the results of the autopsy were not released.
Ms Seery was 42 when she died in 1994 in a Dublin flat.
She was found dead in the property in Rathmines and, following examination, it was determined that she choked to death after a night socialising.
Nobody else was sought as part of the investigation as gardai did not believe any foul play had occurred in her death.
However, during the summer a man walked into a Dublin city garda station and claimed he killed the young Limerick woman.
The man, who is understood to have a history of psychiatric problems, brought detectives to the flat where Ms Seery died and outlined the events of the night to officers, including how he met the deceased and spent the evening socialising with her.
The middle-aged man informed officers whom he was with and his account tallied with information received in the 1994 investigation into her death.
He claimed that he violently attacked her in the flat and strangled her to death.
It is understood that the man was also questioned in a recorded interview in a Dublin garda station after he came forward to officers and gave them his account of how she died.
Any future prosecution will depend on the post-mortem examination and report by Deputy State Pathologist Dr Michael Curtis, along with the man's admissions to gardai.
Ms Seery's relatives had been notified of what has occurred over recent weeks and are said to be extremely upset of the recent events.
