Don't worry, people post stuff to cause upset and panic, the casket was empty the whole time, or maybe had something in that wasn't the body of Michael. Even if the grave did have a number the grave is in a city or suberb with a name and a burial place of rest with a name also so therefore is not a place with no name if you know what I mean. A place with no name I imagine to be a remote far off place that has so far been inhabited and not named yet-there are very many Islands and remote places round the world with no name.
