I agree that it will be messy-and it should. No suspicious death, under any circumstances should go uninvestigated. If something like this happens in Anycity, USA, cops get suspended, all vehicles involved are impounded, witnesses are interviewed, etc while a REAL investigation takes place.
In the meantime, the deceased person’s relatives get lawyered up, as does the city-there is nothing unusual about that-it is their right to do so-circumstances are not always what they seem, particularly when those who are supposed to uphold the law screw up bigtime...
RE: Getting lawyered up. Per the interview, the sisters have not even seen their sister’s body.
Now, if I am dealing with whatever is going on that prevents common decency being observed, you damn right I have a lawyer.
