Missing RAF serviceman Corrie McKeague's mum 'desperate' to find him

The mother of a missing RAF serviceman has told Sky News she is desperate for someone to come forward and say: "I've seen him."

Corrie McKeague, 23, was last seen on a night out with friends early on 24 September in Bury St Edmunds, Suffolk.

Apart from a possible sighting, evidence of his whereabouts is frustratingly thin.

His mother, Nicola Urquhart, said she was struggling to maintain her composure: "It's really difficult as a mother not to be completely irrational and erratic and just run round screaming at everyone.

"It's getting worse every single day because on day one you thought of the simple things.

"As each day goes by it is looking harder and harder and harder that it's going to be a good outcome."

She added: "How did he manage to get out of Bury without being seen on CCTV?

"In this day and age nobody should be able to disappear from a town centre as big as Bury without leaving any kind of digital footprint. Nothing. Absolutely nothing."

Ms Urquhart doubts that her son remained in the town centre, saying that the "area where he last went into has been searched so thoroughly, he's not still in that triangle of shops".

She also thinks it unlikely that he tried to walk the eight miles back to RAF Honington.

"So then it leaves me with two other options," she said.

"Has he left willingly or unwillingly in a vehicle? To me, that is the one that I'm left with.

"Even if he's gone willingly in a vehicle, why hasn't he been able to get in touch since? Has he been taken against his will?"

Ms Urquhart doubts any suggestion that terrorists may have abducted him, but wonders whether local teenagers may know something and are afraid to come forward.

"If you're 16 or 17, and you were out in Bury that night but you don't want to come forward because then people will know that you were drinking, phone up Crimestoppers, it is utterly confidential," she said.

"You might be able to let us know something that really is important."

Just over a month since her son went missing, she said: "I am desperate - and so are the police - for one person to come forward and say to us, 'I've seen him'."

"We need the public's help. That's what's going to find Corrie."
