An inquest is an inquiry to determine the cause of death and if an autopsy is needed or not-the spokesperson for the funeral home stated that there was no evidence of foul play, and stated that Scalia died of natural causes-heart failure/heart attack-I’m pretty sure heart failure is still a natural cause...
I’ve lived in a remote area most of my life-most people die at home here, not in some facility, and so are not attended by a physician-so unless it was suicide, or there is suspected foul play, there is no autopsy unless the family requests it-most families dislike the idea, believing it disrespectful to the deceased unless there is a real reason for it.
Scalia is (was) not "most people" (he was one of the 10 most powerful people on the planet) and Scalia did not die at home.
