THE BOYS' BRIGADE

With that much blood, I have no doubt the dude was beheaded somehow while working on the elevator.

At Maxim, "BLOOD CRUISE: A CARNIVAL CRUISE TRAGEDY RIGHT OUT OF 'THE SHINING'."

And at WFTX FOX 4 Fort Myers, "SWFL couple shows video of 'bloody mystery' on Carnival Cruise ship."

Also at the Orlando Sentinel, "Warning: Graphic Video - Report: Couple witness grisly death scene on Carnival Ecstasy."

It's definitely bloody, so watch with caution.
