You have a body to dispose of. It’s not a pet and it’s not a person you knew very well. Also, you are not the murderer, though it was not an accident. The job of hiding or just getting rid of it was tossed at your feet, literally. What can you do to get rid of a body so that it is never found? After all, your fingerprints are on it now and likely some part of your DNA will be there so simple to not even notice a stray hair or something like that.
