Here's my guess:
Eache robber is going to want the largest share of the money possible.
Therefore The first guy dies automatically because that increases the share
size.  This continues on until there are only two robbers left.  Robber #19
suggests that he receives the full 20 million and since his vote is 50%, he
receives it all.  18 robbers dead.
