The mum of missing Ben Needham from Sheffield collapsed and broke down in tears at the spot where her son disappeared 25 years ago.
Kerry, aged 43, visited the place on the Greek island of Kos where her son Ben was last seen alive, after police officers called off their search of the area.
They spent nearly three weeks excavating two sites on the island, with detectives working on the theory that Ben may have been crushed and buried by a digger.
Ben, who was 21 months old when he vanished, was playing outside a farmhouse his grandfather was renovating when he went missing in July 1991.
A digger was clearing a building plot nearby and it is believed that Ben may have been accidentally crushed.
Yesterday, South Yorkshire Police said the excavation work at two sites of interest had finished.
Ben's mum, Kerry, told the Daily Mirror: “I’d tear up the whole island to find him. I can’t say goodbye until I know where he is.”
Accompanied by her mum and dad, Christine and Eddie, she laid flowers at the spot where Ben was last seen and urged anyone with information to come forward.
“They know he’s dead but just can’t find him," said Kerry
“Police said it’s time we ended our 25-year search. They are right but I can’t say goodbye knowing he’s still on that island somewhere. I feel physically sick. I can’t feel any worse than I do.
“Somebody knows where he is. Somebody else put him there and I can’t say goodbye until I know exactly where he is. Please let me say goodbye to my son. I can’t leave him there on that island. I need to find him. I need to take him somewhere he can be at peace and I can be at peace and grieve for him and somewhere I can remember him."
Ben's family had always believed he had been abducted until police received information in June suggesting he may have been accidentally crushed and buried.
