The sister of the Scots child at the centre of one of the country's oldest missing persons cases says the family is still desperate for answers - 46 years on from his disappearance.
Sandy Davidson disappeared from his grandparents' garden in Bourtreehill, Irvine, on April 23 1976 when he was just three years old.
He had been playing with little sister Donna when he is believed to have chased a family pet dog out of the garden gate.
