couple of silly ideas.
1 he died on concord and his religion stated that he must be buried immediatly he was on lande ( only just poss but extremely far-fetched!
2. He was burried by mistake (ie still alive) and when realised the following day he was exhumed but just too late to save him!
sorry if wasted your time . basically i don't know, but your international date line seems good... but again there must be a reason to rush the interment.
He wasn't David Blain (or Blane) was he ?
