I just found another article:
" The examiners office had said it would conduct routine examinations and look for any evidence of what might have caused her 1990 collapse."

"Routine examinations" clearly mean they are not going to try to do anything, beyond the bare minimum.
No mention of the fact that she was dehydrated to death. And the media wonders why we don't kiss there fricking feet no more.
