I was a paramedic for 14 years. I have seen more dead bodies than I care to remember, in fact, I am still trying to forget most of them.
We had a guy went missing in the river swamps, they found him 6 months later, snagged up on a tree in the river, most of the flesh gone a little hair on the skull, ribs showing very little flesh, still had blue jeans on, had one tennis shoe on, the other foot was a skeleton.

Lots of fun putting that in a body bag, yes sir.

Anyway I have seen it all, and whatever I haven't seen I don't want to see, but no, a body cannot stretch 10 feet.
