I'm not a mechanical engineer but I imagine there's not much recognizable left out of their bodies. The carbon fiber hull is said to have failed catastrophically in an instant shattering to pieces. Water hammered in from all sides with ~400 kg of force applied on every square cm of their bodies + extreme shearing effects. This means they were turned into organic goo in an instant as if passed through a blender. I don't think there's much left of them except for small pieces of bones with a little organic tissue barely hanging on.

Insanely high pressures resulting in insanely high temperatures, instant incineration, followed by a supersonic wall of water smashing everything happening in a small number of milliseconds - faster than anything the mind could perceive.

With the pressures involved, nothing that remains could be identified as a human body. Everything within the ship got rapidly squished and disintegrated.

Mythbusters Pig Diving Suit pretty much explains what happens. Its gross.
