The mother of missing RAF gunner Corrie McKeague has said she has passed on allegations to the police that her son was a victim of a crime.
Nicola Urquhart said she was concerned that police were not taking the allegations seriously after the search focused on a landfill that did not provide any trace of him.
A 20-week search of the site at Milton near Cambridge finished earlier this year, and a second search, lasting seven weeks, finished earlier this month.
Speaking to Sky News, Ms Urquhart said: “We have had various calls suggesting a crime, but when we passed them on to police they took little action to follow them up.”

Suffolk Police has said the investigation into Mr McKeague’s disappearance would remain open.
Mr McKeague was 23 when he was last seen walking through Bury St Edmunds, Suffolk, in September 2016 after a night out with friends.
