I believe the Nov 21, 2019 news story from KRON4 adds some interesting detail.
Still no answers in Utah tech CEO Erin Valenti’s death in San Jose
1) "The coroner’s office says the cause of death is pending toxicology tests and evaluation of medical records."
I know the coroner was waiting for toxicology teats, but I didn't know they were also evaluating EV's medical records.
2) "San Jose police have since offered no new details citing a pending investigation."
So the investigation of SJPD is still open.
3) “So she was having dinner with former colleagues and bosses, many of whom had attended her wedding,” Joseph Valenti said.
So far as I can recall, everything with EV was fine and normal (except a minor thing, she was late in checking out from her hotel). Then there is this last dinner, with "former colleagues and bosses". After this dinner, she couldn't find her vehicle, called her parents, and began acting weird. It is apparent that some happened to her at that dinner. I wonder if she was allergic to something? Or did she ingest a drug or some kind, knowingly or unknowingly? Were I the police, I would concentrate heavily on this last dinner, for logic dictates it was where her troubles began.
