THE family of missing RAF gunner Corrie McKeague have retraced his last-known steps exactly one year after he vanished.

The 23-year-old was last seen walking through Bury St Edmunds, Suffolk, after a night-out with friends.

His mother, Nicola Urquhart, led a group of about 30 people around the town centre on Sunday in a bid to “jog someone’s memory”.

The journey was filmed by Mr McKeague’s older brother Makeyan and broadcast on Twitter.

Mr McKeague, from Dunfermline but based at RAF Honington in Suffolk, was last seen on CCTV at 3.25am on September 24.

Suffolk Police still believe his remains are somewhere on a sprawling landfill site at Milton in Cambridgeshire but called off the search after 20 weeks.

A bin lorry was caught on CCTV near Brentgovel Street in Bury St Edmunds around the time Mr McKeague was last seen.

It took a route which appeared to coincide with the movements of his phone.

The bin lorry linked to Mr McKeague’s disappearance was initially thought to have collected a 24lb (11kg) load but police said it was later found to be more than 220lb (100kg).

A five-month search of a landfill site was called off in July after no evidence of his body was found.

“I know with every fibre of my being that Corrie wouldn’t climb into a bin,” Mrs Urquhart said. “But I wasn’t there that night and people have climbed in bins before, so I cannot say it didn’t happen.”

She added: “It’s the most logical, simplistic explanation as to what’s happened, that nobody else has been involved. So, that’s why it should be exhausted and thoroughly investigated.”

Mrs Urquhart revealed police were still looking into a number of possible sightings of her son.

A police pod was also visible over the weekend in Bury St Edmunds, where investigators were available to speak to members of the public to see if they can generate any new lines of inquiry.

Detective Superintendent Katie Elliott said: "Our thoughts are with Corrie’s family and friends 12 months on from his disappearance. It is fair to say that a year on from him going missing, we never thought we would be in this position of not yet locating Corrie or establishing exactly what happened to him.

"We have always wanted to provide answers to Corrie’s family about what happened to him.

"The search for Corrie remains an active investigation.

"We would ask the public to call us if they have fresh information that may be of benefit to the investigation. We have deliberately placed the police pod on Brentgovel Street as we know this is the route Corrie took on that evening and hope our presence will jog someone’s memory."

Suffolk Police have confirmed that they have further identified people of interest in CCTV images from the night Corrie disappeared.

A group of four men who spoke to Mr McKeague the night he went missing were spoken to by Suffolk Police this month but their interaction with him was deemed not to be significant.

Police have said that the pod was well attended this weekend and they will now process the information they have been told.
