A £50,000 reward for to help find missing Fife airman Corrie McKeague is to be withdrawn.
His mother Nicola Urqhuart said the offer of the cash put forward by an anonymous business couple, will end on Saturday.
The news comes as police prepare to search a landfill site in Milton in Cambridgeshire.
Corrie, who has family in Cupar and Dunfermline, disapeared following a night out with friends in Bury St Edmunds on September 24.
Despite huge search and social media campaign, he has yet to be found.
Now his mum, Nicola, says it is time to withdraw the reward.
It will be formally taken down on February 18.
Writing on the ‘Find Corrie’ Facebook page, Nicola said: “In early December 2016, a £50,000 reward for information leading to Corrie being found was offered. The reward was kindly and very generously put forward by a business couple, local to Suffolk.
‘‘It was their wish that they remained anonymous. At this moment in time, the offer of a reward hasn’t brought to the fore, the information we had hoped for.
“Following discussion, we consider it sensible that the offer of a reward should not remain in place indefinitely. As such, we have decided to leave a reward in place for one more week.
“On behalf of my family, I would wish to publicly thank from the bottom of our hearts the couple concerned.
“Not only have they offered what would be to most of us, a life changing sum of money in the shape of the reward, they have also given their time and made great efforts to assist us find Corrie. We will be forever grateful to them for this.”
Corrie is originally from Fife and moved down to Suffolk to live at RAF Honington where he worked as a gunner and team medic in the air force.
