As I recall, according to Michael, Terri didn't like "bugs". That was the reason to honor her "wishes" to be cremated. Greer agreed and that is why the Schindlers were not successful in their endeavor to have a normal burial.
And despite what I posted about Florida's cremation laws, Thugmartin didn't delay it by one minute.
Yeah, yeah, yeah. I suppose that's why he wouldn't let her have religious medallions or cards in her room, and why he wouldn't let her take Holy Communion (2003 murder attempt). Michael was being his usual spiteful self, inflicting as much evil as he could conceive on his victim. Like any sociopath, he blamed her for what he did.
Contrary to Florida statute, the M.E. was by no means "assured that no future question will arise about the cause or circumstances of the death of the individual" when he did it.
I can think of a question or two that either went unanswered or got dubious answers that needed rechecking. I have no doubt that a top pathologist could think of several more very pointed questions.
