The fate of a schoolgirl who disappeared more than 50 years ago remains a mystery after a grave search found no evidence of her remains.
Moira Anderson was 11 when she failed to return home from running an errand in Coatbridge, North Lanarkshire, in February 1957.
Following a two-day search of a grave plot at Old Monkland cemetery in Coatbridge, chief inspector Kenny McLeod from Strathclyde Police said: "I can confirm that Moira's remains have not been found. The case will remain open."
It is widely believed that Moira was abducted and murdered, but her body has never been found.
Detectives recently reopened the case, focusing on a family grave plot where they believed it was possible that her body may have been dumped.
Convicted paedophile Alexander Gartshore, a Coatbridge bus driver who died in 2006, has been connected with the schoolgirl's disappearance.
On Tuesday investigators began excavating the plot of Sinclair Upton, said to have been an acquaintance of Gartshore, to see if the youngster's remains were put there.
The operation was led by Professor Sue Black and a team from the forensic anthropology department at Dundee University.
Mr McLeod said Moira's family has been made aware that searchers had turned up a blank.
The officer stressed that it did not mean the search for the missing girl was over. "Any further lines of inquiry will be fully investigated," he added.
