Police searching for a missing RAF man are confident they are right to be searching landfill after new information emerged about waste collected from the cul-de-sac where he was last seen.
Detective Superintendent Katie Elliott said data about the weight of rubbish collected from the 'Horseshoe' area had been found to be incorrect.
"We now know the weight of the waste collection from the Horseshoe on the night Corrie went missing was over 100kg, when the original information we were given indicated that this was 11kg, and this makes our search of the landfill the next logical step to try to find Corrie," said the detective.
Corrie McKeague, who was stationed at RAF Honington in Suffolk, was last seen in Bury St Edmunds in the early hours of 24 September 2016.
CCTV showed him entering a cul-de-sac loading bay area known as the 'Horseshoe' at 3.25am. However, there was no sign of him leaving.
"The investigation has identified that the company who provided the data usually charge per collection, not per weight of load collected, and it appears that it was genuinely believed by the company that the data provided was correct," Det Supt Elliott said.
"There was no intention to mislead the investigation, however our discovery, through persisting with this through our inquiries and evidence gathering, now puts a new emphasis on the search.
"Corrie's family have been made aware of this new information and we continue to liaise with them as we move forward."
Police have moved 8,000 tonnes of bulk material at the landfill site in Milton, Cambridgeshire in order to carry out the search safely.
It is expected to begin later this week.
The details about the rubbish carried by the truck came as police said a 26-year-old arrested on suspicion of perverting the course of justice would face no further action.
