A submarine went missing, and body parts were found a week later in the water (2023x49)

:

The submarine went missing, and the whole world stopped to watch. Two people were trapped inside - underwater with only hours of oxygen left. Would it be possible to find them in time? People wondered if it was engine failure - or maybe the sub had imploded. But the mysteries kept piling up - why did the submarine sink? Why did only one person make it out alive? And why were body parts washing up ashore?
