A missing airman who is believed to have climbed into a bin was a "heavy sleeper when drunk."
Corrie McKeague disappeared from a night out in Bury St Edmunds in September 2016.
The 23-year-old gunner, from Dunfermline, Fife, was last spotted on CCTV at 3.25am going into a service area behind a Greggs bakery and police reckon he climbed into a bin which was tapped into a waste lorry.
