They get attacked. They die. Satisfied, the attacker leaves. Later, Mansi come across remains. They say nothing. Someone else comes along, digs up the bodies. They get thawed, washed and dressed at the morgue. Someone else says put them back the way you found them. OK.. Later, college kids find a few bodies. Some are dressed funny. Some are flipped around. They get autopsied. Still later, more bodies are found. The same happens to them. With difficulty, all bodies get flown home.Some are buried in one place, some in another. One may not be buried where we think at all. Can't pin it on Mansi. Can't pin it on geologists. Can't pin it on prisoners. Can't pin it on military. Can't pin it on anyone. The whole matter is hurriedly concluded. It and the region are off limits for varying lengths of time. Conclusion, those who originally dealt with this were as much in the dark as we who come after. Me, I like the slab slide idea.
