When i saw Claus twitter that he was coming over to play at St Marys i too thought that strange,i think it ties in nicely with the above,or something very similar.
They could not have buried him on land,the place would've become a shrine,however much of a secret location it would have been.
He did not get an Islamic burial,if the said person dies at sea and cannot reach land it is permitted that they can be buried at sea.
If not, they have to be buried on land and again within 24 hours.
