I pulled up near a gas station. I told the service station guy to give me all of his money. I then took him to the bathroom and told him to kneel down and then I shot him in the head twice. The guy didn’t give me any trouble but I just felt like I had to do it. [The next morning, I left my car at another service station] I went in and told the guy to give me the money…Then I shot him.
