While living in his house boat a guy tries to rob him. He says he’ll give the robber everything he’s got. He goes to the bin where he has a gun and pulls it out on the robber. The Robber freaks and jumps into the river to swim away. The other guy is pissed and would have chased him to apprehend the villain so he doesn’t do it again but is questionable about jumping into the nasty river with his expensive close. So he tries to shoot at the guys feet so he is forced to swim out eventually and he’ll go along the river waiting. Instead he shoots him through the heart.
