Forget Me Not: Corrie McKeague

Corrie McKeague went missing from the Bury St. Edmunds area on 24 September 2016 at the age of 23. He was an RAF Reginment Gunner and father to one. He has not been seen since. It is largely accepted that Corrie fell asleep in a bin and ended up at landfill, never to be found, but is it as clear cut as this?
