I think it's likely that the hotel is trying to cover their @$$ and are making some mistakes and PR blunders in the process.
Also, in today's information age we expect to have an answer to everything and understand every incident within a short period. Sometimes things are inexplicable and we may never understand.
Not sure what the hotel really did wrong.
Even if this were true, and the hotel was covering up some mistakes or wrongdoing, their coverup would most likely be uncovered by the feds, and even if it wasn't entirely uncovered, it still doesn't explain the strange silence and lack of information on this story.
