If someone is unconscious for 6 years, and NOT embalm when put contained by the coffin, what's the condition of the body very soon?

The answer is it depends on the type of coffin, and whether or not its maintained its structural integrity.
If its a wooden coffin that have its structural integrity the body is desciated, probably still identifiable.
If the coffin has broken down at adjectives the body is probably mostly bones by now.
If its one of those steel airtight coffins. the body is in a minute mostly liquid.
Bones?
Dust.
depends on what sort of soil they are buried surrounded by,but mainly bones and a bit of pelt and skin.but definatly not dust.
