They should just leave it alone. I think at the back of their minds, they would find a well-preserved body like what you read in the books due to the Holy Divinity.
St. Peter’s bones (or bones BELIEVED to be St. Peter’s) which were found under his basilica in Rome are just bone.
If there’s a hole to push cloth through, then it’s big enough to put a scope through and they can see what’s inside before doing a thing.
