Geez that sucks.
If they kill other one, too, we’ll never find out provide them with money, equipment, and marching orders, spiritual support. I don’t believe for a second that they did by themselves.
Of course, since the survivor would get the best lawyers the Moslems could buy, we probably wouldn’t find out anyway.
They had money to fund this. They had money to live off of. Why all of a sudden did they have to rob a convenience store for cash???
