Whatever the death toll figures are reported, the actual number is likely to be many times of these official figures.
If you have been to such areas, you would have seen how the area is like. I believe there are many people not properly recorded in official govt records, undocumented people etc. There will be people living in ultra secluded areas, homeless people too. Especially on Nepal's side.
The extent of the damage means many many bodies will never be recovered, be it buried deep under all that silt and mud, or torn to pieces by the debris. That flow is full of debris, rock, stones, ice. It's like a washing machine filled with sand, that kind of abrasive power.
RIP.
