The Medical Examiner ruled that this wasn't a suicide or murder and that there was toxic levels of alcohol involved.
So, once you evaporate antifreeze does the ethylene glycol further separate into its alcohol component?
This case still bothers me ~ thinking of the risk taken by all those rich people who park their more expensive SUVs inside their garages. (/s)
Ethylene glycol won’t break down to alcohol. No, I have not done any fire experiments yet this year.
I think sometimes the police like to close a weird case, and will accept or gin up a weird reason for all the loose ends.
