Idiot or killed.
Anyone who ingests fish tank cleaner is definitely an idiot. What purpose would be served by killing him?
And being an engineer .... well, that says it all right there. :-)
The latter sounds more reasonable.
My speculation is he was murdered by his severely TDS infected wife. The death of her husband is a small price to pay to cause PDJT trouble just to satisfy her thirst for PDJT blood.
This is the problem with madness unchecked. I spirals into an implosion.
