A search for missing RAF airman Corrie McKeague appears to be closing in on the area where his body could be found, his parents have said.
Officers scouring the landfill site in Milton, near Cambridge, are finding rubbish dating close to the time he was last seen on September 24 last year, the Daily Mail reports.
They began sifting through 8,000 tonnes of waste in early March and Corrie's mother Nicola Urquhart said the task could take a further four weeks.
The operation is now focused on one particular area.
Urquhart, of Dunfermline, said: "Although the search doesn't start again until Tuesday, I pray we get some news this week.
He wrote on Facebook: "They've even told us that where they're now looking, they're finding more and more mail and newspapers with dates and addresses near to the time and area where Corrie disappeared.
"While I dread the thought of finding my son here, not knowing what's happened to him is almost worse."
Urquhart said even though she believes he is at the landfill, the vehicles that were in the same area the night Corrie disappeared are still being investigated.
She said: "Given the information that the police have give me and stuff that I know I would say I'm just like the police - absolutely amazed that Corrie has not been found yet in the landfill site.
"All of those vehicles are still being looked at because he must have gone in one of them.
"None of the vehicles have been ruled out completely at this point, they've not been able to say that none of them have had anything to do with it completely so they are still carrying out enquiries."
She added: "It's still my belief that Corrie will be found at that landfill, that's what I think and that's what police think and they do still have another four weeks of searching potentially.
"Although it's impossible waiting for the landfill to be searched we will manage."
Corrie, 23, from Fife, a Royal Air Force Regiment gunner, has been missing since a night out in Bury St Edmunds near his base at RAF Honington.
He was last seen in the early hours of September 24 walking into a loading bay known as the The Horseshoe which is used as a bin store.
A bin lorry linked to his disappearance was initially thought to have collected an 11kg load but was later found to have been carrying more than 100kg.
