It's undisclosed, actually

To the person who found me by searching "someone dies ground is frozen what do with the body," I'm very sorry for your loss. I don't know what they do with all bodies, but my mother's is in "a very secure place" owned by the funeral home.

Truth be told, it freaked me right out how insistent they were that it's secure. Great. Another thing to be weirded out about. Not only is she dead, but some psychotic necrophile might try to take her body. It's bad enough that--well, it's bad enough.
