Sorry to say, but as we speak, the cabin is occupied, and on the ocean.
Cabins are returned to normal as soon as the FBI releases it.
I had a cabin steward once who was on the clean up crew for things like this. Blood is not easy to remove due to the salt content of cabins, who are constantly exposed to sea air.
Yes, I have stayed in a cabin where the occupant died, and no they did not disclose it. I am nosy.
No I did not see a ghost, but the ice bucket always seemed like it had ice.
