Dogs specially trained to find dead bodies have been drafted in to search for missing Fife man Corrie McKeague, his mother revealed.
Nicola Urquhart, 48, said the Cadaver dogs are being used by Suffolk police to find her missing son.
But despite the animals being trained to find corpses, the serving police officer insists RAF gunner Corrie, 23, could still be alive.
Writing on Facebook, Nicola said authorised searchers from Suffolk Lowland Search and Rescue have been allowed to use the dogs in the town centre of Bury St Edmunds, Suffolk.
Writing on the Find Corrie Facebook page Mrs Urquhart said: “It’s with mixed emotions that I can let you know the police have authorised SULSAR to use Cadaver dogs in specific areas in the town centre, I will update you once this has been completed.”
She posted the comment after receiving inquiries from concerned supporters on the page which has more than 100,000 members.
Also posting on the page Mrs Urquhart said that a lorry with a large TV screen displaying pictures of Corrie and CCTV images of people police still want to speak to would be driven around Bury St Edmunds.
She said: “This is something that we are working together with Suffolk Police MIT (Major Investigations Team) so that we can get all images of every person still unidentified out to those that maybe don’t have access to internet.
“The details of where and when will be provided as soon as we have them all confirmed.”
Corrie has been missing since disappearing after a night out in Bury St Edmunds, Suffolk, on 24 September.
Last week week Nicola Urquhart made an appeal for her son’s return in an interview with Phillip Schofield and Davina McCall on ITV’s This Morning.
Choking up, Nicola said: “I realise as each day goes by the chances of him being alive are slim but without someone saying he is, I’m not giving up.
“Someone could be holding him, but, if they are, the public support is amazing.”
It also emerged that Corrie’s girlfriend April Oliver, 21, is pregnant with his child.
Miss Oliver said Corrie did not know about the baby which is due in late spring or early summer.
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.
