I would imagine something similar to the worst of the Byford Dolphin decompression accident, which was a torso and large limbs crushed to the point of being almost unrecognizable with internal organs and some chunks of soft tissue separated from the body. Photos of that exist and you can find the relevant research paper by googling “Byford Dolphin Autopsy,” but seriously those pictures are gruesome. In the case of the Titan, because the hull was compromised, large portions of those bodies were probably lost to the sea.
