A post-mortem examination is being carried out in Belfast today on the body of pensioner Attracta Harron, found hidden near a stream.
A specialist search team discovered the body near Sion Mills in Co Tyrone yesterday afternoon.
Mrs Harron, from Strabane, had been missing since December 11. She was returning over the border from Mass in Lifford, Co Donegal.
The body had been buried near a stream on the Concess Road, about a mile outside Sion Mills.
Her identity was confirmed last night after the body was taken to Foster Green Hospital in Belfast.
Det Insp John Gilmore, who has been heading up the investigation into Mrs Harron’s murder, said the body had been “concealed under the ground”.
Police on both sides of the border have been working closely to try and trace her.
Extensive searches were conducted in Strabane, Sion Mills and Lifford. A total of 14 detectives were assigned to the case.
Last month a 21-year-old student appeared at Omagh Magistrates Court charged with the pensioner’s murder. He was remanded in custody until April 22.
