Medical investigations were carried out on the remains of the four divers. The most notable finding was the presence of large amounts of fat in large
arteries and
veins and in the
cardiac chambers, as well as intravascular fat in organs, especially the
liver.
[3]: 97, 101 This fat was unlikely to be
embolic, but must have
precipitated from the blood
in situ.
[3]: 101 The autopsy suggested that rapid bubble formation in the blood
denatured the
lipoprotein complexes, rendering the
lipids insoluble.
[3]: 101 The blood of the three divers left intact inside the chambers likely boiled instantly, stopping their circulation.
[3]: 101 The fourth diver was dismembered and mutilated by the blast forcing him out through the partially blocked doorway and would have died instantly.

Coward, Lucas, and Bergersen were exposed to the effects of explosive decompression and died in the positions indicated by the diagram. Investigation by
forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal
organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic
spine. These were projected some distance, one section being found 10 metres (30 ft) vertically above the exterior pressure door.
