I'm sorry for your loss.

I have been looking into these issues and have not been able to find alot on these terms. I will continue looking into it and when I am confident about a definition I will relay it to you. Hopefully, someone else on here will do a better job of researching than I am able to at the moment.(I have a firewall at work). And will be able to offer you some better information.

Are you trying to research a cause of death, or determine if you agree with the ruling on the cause of death?
