The grandparents of missing RAF gunner Corrie McKeague, who vanished on a night out, have offered a five figure reward for information leading to his discovery and return. 

Mary and Oliver McKeague, from Cupar, believe their grandson's disappearance may involve a third party.

The 23-year-old from Dunfermline has been missing for over 10 weeks now after a night out in Bury St Edmunds.

Grandmother Mary McKeague said: “I can’t describe how empty and helpless you feel when a family member goes missing.

"This is what has happened to us. This is why we’re here. To ask for your help.

“We’ve pledged this reward in hopes that it will motivate someone to come forward and help us find my beautiful grandson, Corrie, who went missing the day of his stepmother’s birthday.

"We’re heartbroken, but we’re not giving up. Corrie would expect us to stay strong.”

The search has been widely reported because of two suspected kidnapping attempts of military servicemen earlier this year. 

Corrie's grandfather Oliver said: “Corrie’s base at RAF Honington is near two other military bases, RAF Marham to the north, and Aldershot Camp to the south, and each recently reported suspected kidnapping attempts of military servicemen.

"You could draw a near straight line on a map and connect all three. Corrie’s base is right in the middle.”

A qualified Gunner and Team Medic, Corrie joined II Squadron RAF Regiment three years ago and lives on the RAF Honington base in the southeast of England with his black pug puppy, Louell.

Corrie’s last sighting shows the young squaddie walking from a shop doorway and walking into a horseshoe-shaped area at 3.25am in Brentgovel Street and no sighting of him emerging.

Oliver said, “The CCTV cameras show him walking in but not coming out. He seems to have just vanished. But people don’t just vanish, they leave or they get taken away.

“We think Corrie arranged to meet someone that night but we don’t know who, and then got into a car and disappeared.

"We know he didn’t just run away; he loved his fellow squaddies, his life and the career direction he had chosen.

"He was so proud the day he passed out and joined 2 Squadron RAF Regiment three years ago, and so were we.”

The McKeague family are asking for any information from anyone who may have been in the town that evening or who may know of Corrie’s whereabouts to call Crimestoppers on 0800 555 111.
