Very sad outcome and the remains will have been scavenged by marine life soon after the breakup. It's likely they suffered the same fate as the saturation divers from the Byford Dolphin disaster who were killed when the pressurised diving chamber they were in was suddenly depressurised. The force pushed one of divers through a hole the size of a fist which mutilated the body instantly and it scattered remains of the other divers and internal organs around the inside of the diving chamber. The blood doesn't boil in the veins but it instantly becomes a thicker substance and stops circulating. If that happened to the people on the sub it may have been more a more preferable way to go than slowly and helplessly suffocate. The sub doesn't look like fail safe measures were high on the priority list.
Sorry, but what you are describing is more like a DECOMPRESSION incident like an explosion in a space capsule, not an implosion in a submarine.
In this accident: The water pressure on each square inch of the submarine was about 2 and a half TONS, when the chamber walls failed the water would rush in in a split second and exert that 2 1/2 tons on each square inch of each human person. So each person would be squished, the fluids are generally not compressible though they would stiffen under that pressure, but every chamber, especially the lungs and abdomen containing air (or other gas) pockets would be squished to less than 1% of their normal size, All the chest bones would break immediately probably wrecking the heart. The head too with its air pockets in the ears nose and throat would also be instantly ruined.
I suspect that the incident you quote was in a decompression tank with a mere 45 pounds per square inch, with the divers in there, for several days, because they had been diving at say 150 feet (58 psi) and had nitrogen dissolved in their blood, which takes time to come out to avoid "The Bends" (decompression sickness).
I suspect that the Titan submarine ran with an internal pressure approximately the same as our atmosphere (about 14.5 psi) , so that the passengers would not need to be decompressed when they (normally) got back to the surface.
Gruesome description, I know, but at least death would be very very quick.
