Well, it isn't required (except maybe for Muslims) that someone be buried immediately after death. My father's funeral was delayed a month at my request, and it posed no problems for the undertaker in the UK.
I understand that, but the article I posted said he died on Wednesday, which would have been May 28th. Quite a disparity I'd say. Wikipedia says Mar 28th so there could have been a typo in my article, only one letter difference.
