Astounding but true.

This is the second case of cannibalism:

I ignored the first case. I did so because I did not have the stomache for it.

It concerned two persons digging out the grave of a child and and were proposing to dine on it!!!!!!!!!!!!!

Questions:
How did these persons become this way in 2014?

How many more of these are there?
