THE father of missing serviceman Corrie McKeague has revealed that he feels he has “lost all three” of his sons over a family dispute in the wake of the RAF gunner’s disappearance.

Martin McKeague, from Cupar in Fife, said he has had no contact with sons Makeyan, 26, or Darroch, 21, since the family rowed days after middle brother Corrie, 23, vanished in September last year.

Mr McKeague, who split from his sons’ mother Nicola Urquhart 14 years ago, said: “When something terrible happens, you hope your family will pull together. But we have fallen apart.

“The last time I saw Makeyan and Darroch, it was emotional. We were upset, things started to get heated and I had to walk away.”

Mr McKeague said he did not want to disclose details of the argument but said he did not understand why his sons had “turned against me”.

It comes after it emerged on Saturday that police searching for Corrie, who was brought up in Dunfermline, have traced a potential witness.

They are speaking to a cyclist who was seen on CCTV in Bury St Edmonds, Suffolk, around the time as Corrie vanished following a night out with friends.

The serviceman was last seen walking towards a refuse site in the town at 3.24am on September 24. He was reported missing on September 26 when he failed to turn up for duty at RAF Honington.

In December, the McKeague family announced that they were offering a five-figure reward for information which leads to Corrie’s discovery, branding the Suffolk police investigation “incompetent”.

It also emerged in January that Corrie’s girlfriend of five months, April Oliver, is pregnant with his child.

Last week, police announced they were to begin searching the landfill site in Bury St Edmonds for Corrie.

Mr McKeague said this had been a “body blow”.

He added: “Searching the landfill site will be a biblical task, it is so huge, and all we can do is wait – and it’s a gruelling, agonising, gut-wrenching kind of waiting.

“We just want answers about what happened to our boy, and we want him back.”
