Police and forensic experts are to reopen a family grave today in search of the body of missing schoolgirl Moira Anderson.
Moira was 11 when she went missing over half a century ago from her home in Coatbridge, North Lanarkshire, in February 1957.
It is thought that she was abducted and murdered, but her body was never found.
Experts are looking into the possibility that Moira's body could have been dumped underneath a coffin in the grave, which might have been open at the time of her disappearance.
