“If they are thorough, which the LA corner is, they will find a cause.”
Not so sure about that. My SIL died in her 50s in Brentwood, apparently healthy. The LA coroner / medical examiner investigated, but they never gave us an answer — just a lot of bagglegab. That was late in 2007. We weren’t impressed.
Did you ask for a private autopsy? Under the law you can request it.
