I'll add this to the OP.

A completely random person will die. If you kill someone it doesn't count. You will be hunted and stabbed to death by a murderer. The person who dies gets no money.  Not even for his family. 

Do you get to fight back? Because I think I could take a murderer with a knife. And if you beat him does he go after someone else? Or do you get to kill the murderer in self defense and collect the 10m?
