The RAF Honington serviceman has not been seen since he went for a night out in Bury St Edmunds almost three weeks ago on September 24.

CCTV footage showed him in Brentgovel Street at 3.20am on the Saturday morning but he has not been since.

One of the theories from Suffolk Constabulary is that he intended to walk back home.

“Please come back I’m missing you so much and so is everyone,” wrote his niece Tyler.

She later adds: “I am writing this note because we are missing you so much.”

Tyler’s mum Kelly Watson posted the letter on Facebook, saying: “My daughter wrote this for Corrie (her uncle). She just wants him to come home safe and be with his family.”

Police are pursuing a number of enquiries and searches for the 23-year-old continued yesterday.

Corrie’s mother Nicola Urquhart shared more pictures of her son yesterday, saying: “Please keep Corrie in your thoughts. My boys are my world. Please keep sharing. No matter how unimportant you think it may be. If you were out on Friday, September 23, in Bury please let the police know.

“If you have CCTV please make it available to the police. You could bring Corrie home to us with information you maybe didn’t think was relevant. It’s never too late to contact the police.”

Corrie has been based at RAF Honington three years this month and often went on nights out in Bury.

More than 20,000 leaflets have been printed free of charge by local printing firms in an overwhelming public effort to find him.

An expert sniffer dog search team searched along the A134 this week, but was unable to find any trace.

Searches have also focused around the Barton Mills area after data from his mobile phone placed it in that area.

A key line of inquiry remains finding the phone, which is a Nokia Lumia.

Anyone who spoke with Corrie in Bury the night he vanished should contact police.

He had a Scottish accent and was wearing a pink Ralph Lauren shirt, white jeans and brown suede Timberland boots.

Corrie is described as white, 5ft 10ins tall, of medium build, with short light brown hair.
