The father of missing RAF airman Corrie McKeague believes his son may have killed himself after learning that his girlfriend was pregnant.
Martin McKeague has revealed his theory that his son found out that he was going to become a father and that may have had a 'profound effect' on his mental health.
Martin, 49, said the news would have had a ‘profound effect’ on Corrie’s mental health, and that he may have chosen to ‘get in that bin that night knowing what would happen’.
April Oliver, 23, has always maintained that she only found out about the pregnancy two weeks after Corrie was last seen.
It comes as it was suggested the inquiry into Corrie's disappearance will be stood down and passed to a cold case team amid mounting costs and a lack of leads.
Mr McKeague was 23 when he was last seen walking through Bury St Edmunds, Suffolk, in September 2016 after a night out with friends.
Police conducted two searches of a landfill site near Cambridge last year, with the first search lasting 20 weeks and the second concluding in December.
No trace of Mr McKeague was found.
It is thought Mr McKeague may have climbed into a waste bin and was taken away by a bin lorry, prompting the landfill search.
The Daily Mirror reports Suffolk Police will announce the inquiry will be shelved – as Mr McKeague's father Martin said he fears the airman may have killed himself.
Martin, 49, added: 'I just can't help thinking this would have weighed on him heavily and he may have actually chosen to get in that bin that night knowing what would happen.
'It's as probable as anything else and it makes it no less heartbreaking.'
In January, it was revealed that the investigation into Corrie's disappearance has cost £1,325,000 plus salary costs of £826,000, Suffolk Police said.
The force added that around 34,000 police officer hours had been spent on the case, not including police staff time or overtime hours.
The total number of police officer overtime hours spent working on the case to date is more than 5,600 hours, costing £235,000.
This figure excludes overtime that will be paid in January relating to December claims, and the force said data about police staff overtime hours is not held.
A Suffolk Police spokesman said: 'Careful consideration is always given to all decisions regarding the resourcing of any long-running major investigation.'
No trace of Mr McKeague was found during the police searched but they are 'committed to continuing with the inquiry'.
Mr McKeague, from Fife but based at RAF Honington in Suffolk, was last seen on CCTV at 3.25am on September 24, 2016.
