As my parents went out to dinner, I contracted a murder
Did you really do that? Why would you contract a murder?
I can tell you later.
I think murder is the worst crime that you can commit in the United states, and in any other country for that matter. So I don't understand why you have contracted to murder someone just because your parents are away for dinner. There are a lot of things that you can do to entertain yourself, so I would suggest that you either just watch a movie, play video games, or maybe go on a date yourself instead of killing someone.
I can assure you that it's all under control.
Eventually your confession will be traceback and you will be just as guilty as the person you hired. Convicted murderers are not good people.
