The mother of missing Suffolk airman Corrie McKeague has said she believes a person caught on CCTV wearing “incredibly bright” clothing could be her son - but police have revealed they have identified the man in question.

Nicola Urquhart said people would be “horrified” to see some of the CCTV footage taken around the time of her son’s disappearance back in September 2016, as it casts doubt on the police theories over Corrie’s whereabouts.

In one piece of footage, three individuals are seen, at a distance, walking away from the ‘horseshoe’ area in Brentgovel Street, where Corrie was last seen.

Mrs Urquhart said she had viewed CCTV footage and described it as “grainy”. However, she said it showed a person “wearing incredibly bright, reflective clothing, which looks like white trousers” leaving the bin loading area.

On the night he disappeared, Corrie was wearing white jeans and a pink shirt.

Police viewed the footage during their early investigations into the disappearance of the RAF Honington serviceman and have ruled out any connection with Corrie’s disappearance.

A Suffolk police spokesman said: “The investigation into the disappearance of Corrie McKeague resulted in over 2,000 hours of CCTV footage being viewed by detectives and technical support staff.

“Corrie was last seen on CCTV entering the ‘Horseshoe’ in Brentgovel Street at 3.25am. All persons entering and leaving this area between 3am and 6am have been captured on CCTV recordings and their movements tracked by investigators. Each person has subsequently been eliminated from the enquiry.”

Referring specifically to the footage Corrie’s family have questioned, the spokesman added: “In order to provide particular reassurance as to the identification of those persons captured, Suffolk Constabulary can confirm that the three individuals were tracked walking into the area and away from the area.

“ These individuals have been spoken to by police and identified themselves from these images. They confirmed their presence in the area and the reason for their presence.

“Detectives involved in this process are therefore confident that none of the three persons is missing airman Corrie McKeague.”

Corrie was last seen entering the bin loading bay when he was on a night out in Bury St Edmunds leading police to believe he had gone into one of the bins.

But his remains were not found despite a 20-week trawl of a landfill site at Milton, near Cambridge.
