Yep, same in my home state. My gf's mom actually was the coroner in the neighboring county, she was no doctor, nurse even, etc. We did have a doctor as ours for a period of time but the one after him wasn't.
The FBI was present and handling so not surprised there was an ME with something like this.
The family knows she is deceased and so I assume she was on the boat and not overboard but there's little info that's come out. It was also said it was a quick turn around. The FBI was on the ship just part of one day and then the cruise ship left. Also the ME seems to confirm her body was on board of course as the ME said she died Friday.
It isn't even out who she went on the ship with i.e., with family or friends or alone, etc.
