Might be wrong but...Wasn't it that the family said no to an autopsy. Didn't know you could do that.
Also, a judge pronounced him dead without seeing the body.
Typically, any death without a physician present to call the time of death, or an unattended death, automatically becomes a coroners case and an autopsy must be conducted to determine the cause of death. Old Age is not a cause of death. Death in hospital from a diagnosed condition would not necessarily require autopsy. Catholics are known to be opposed to the autopsy, and after autopsy we would return the organs of the deceased to the family (in a hefty garbage sack sewn back inside the body) as it was deemed important to them to have as much of the remains as possible to inter.
My experience was from a different county in a different state in a different era (middle-late 70s) but I was shocked at the apparent lack of procedure in West Texas after the dearly departed Justice Scalia case.
Question. Why are seven members of the Supreme Court about to be Catholic and the other two Jewish?
