Police and forensic experts are preparing to reopen a family grave in the search for the body of a schoolgirl who vanished more than half a century ago.
Moira Anderson was 11 when she went missing from her home in Coatbridge, North Lanarkshire, in February 1957 while running an errand for her grandmother.
It is widely believed that she was abducted and murdered, but her body has never been found.
The case remains unsolved, although convicted paedophile Alexander Gartshore, a Coatbridge bus driver who died in 2006, has been connected with the disappearance.
Investigators will on Tuesday start excavating the plot of Sinclair Upton, who was said to have been known to Gartshore, to see if the schoolgirl's remains were hidden there by her killer.
The exhumation of the gravesite at Old Monkland Cemetery in Coatbridge, which is reportedly known to contain eight bodies, is expected to take several days. Final preparations for the work were being carried out at the site on Monday.
The operation, which will be conducted by Strathclyde Police and led by forensic anthropologist Professor Sue Black, comes after a sheriff gave the green light to the move last month.
The process will involve highly-skilled personnel trained in the techniques required for this type of work, police said.
Experts are exploring the possibility that Moira's body may have been dumped under a coffin in the grave, which was thought to have been open around the time of her disappearance.
Gartshore was blamed for Moira's murder by his own daughter, Sandra Brown, in her book Where There is Evil.
