Watery death—Do I leave a body?

[Survivor-Kyle 148]

If a player were to, hypothetically, loot Rify but then get catapulted down some stairs and flung overboard, would they leave a body? I spent a while running back to check, but couldn't find one anywhere in the water :(

"Hypothetically", I doubt it very, very much. Even if so, it would be on the sea bed wouldn't it?

Bodies disappear in 10 minutes or less without any players around to prevent cleanup.  Rifles that are in hands will drop and persist for some time longer.
I haven't tested in in .63/1.0, but watery graves were indeed unlootable.  Found multiple bodies on the seabed near prison island.
