It could be just one phone call or piece of evidence that makes the difference to the Moira Anderson investigation.
Police say they are determined to find her remains, which could finally conclude that Alexander Gartshore was responsible for the 11-year-old’s death.
Prosecutors are so convinced he is the killer that in 2014 they issued a statement saying that, if he had still been alive, he would have been indicted for Moira’s abduction and murder.
