Gardai are to excavate a shallow grave in their search for missing Donegal girl Mary Boyle.
Mary was just six when she went missing at Cashelard outside Ballyshannon in 1977.
Gardai have visited the lands in recent weeks where Mary was last seen as they reviewed the case.
Despite being reported to Gardai on three different occasions, the area of land has yet to be dug up.
Mary’s twin sister Ann said she also wants the area examined as she said she has always believed Mary was never moved from the mountain where she disappeared.
In recent weeks a team of officers under Assistant Garda Commissioner Kieran Kenny have taken fresh statements into Ireland’s longest running missing person case.
The Sunday World newspaper has today published a special supplement on the case.
They interview the last person to see Mary alive – her uncle Gerry Gallagher.
Ann said she never believed child killer Robert Black, long claimed to be linked with the case, was ever involved in Mary’s disappearance.
Ann said “I believe she is on the mountain. And I am sure the truth is closer to home.”
Ann said she had never heard claims about a shallow grave and the fact that it had not been searched.
However, she said if there is such a location then it should be searched immediately.
