Police investigating the disappearance of RAF serviceman Corrie McKeague say there is currently “no evidence held to suggest criminal involvement”.
The force said it has remained open minded throughout the inquiry and will ensure that all “proportionate and relevant lines of enquiry” are completed.
The statement comes after Corrie’s mother, Nicola Urquhart, said she has passed on allegations to the police that her son was a victim of a crime.
Mrs Urquhart said she was concerned that certain leads had not been followed up after the search focused on a landfill site in Milton, Cambridgeshire.
Two searches, which in total lasted 27 weeks, provided no trace of the RAF Honington gunner.
Corrie went missing after a night out with friends in Bury St Edmunds in September 2016 and was last seen on CCTV at a loading area behind Greggs, known as the Horseshoe.
Speaking to Sky News, Mrs 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.
“I spoke to the senior investigating officer two weeks ago and mentioned one call that we alerted them to, but she said she knew nothing about it.”
Mrs Urquhart told this paper yesterday that she was confident that other lines of enquiry are now being followed up.
A Suffolk police spokesman said: “Police are continuing to investigate the disappearance of Corrie McKeague.
“This will involve re-examining the evidence relating to other theories to identify whether there is anything else that can be done to establish what could have happened to the RAF serviceman.
“We will ensure that all proportionate and relevant lines of enquiry have been completed, in order to be able to provide answers to the family and help them understand what may have happened to Corrie.
“Throughout the investigation police have remained open minded about what may have happened to Corrie and this approach was confirmed by the East Midlands Special Operations Unit review team.
“There is currently no evidence held in this investigation to suggest criminal involvement in Corrie’s disappearance.”
