And they were all very wrong.☺
Btw, they would have known almost immediately there was no obvious foul play involving the dog either. ie, no signs and physical trauma, injuries etc. I was pretty confident from the beginning this was not a who done it.
At the beginning you would have been disagreeing that it could have been a gas leak, the first responders and law enforcement dived into that along with the public.
Still some unanswered questions though...about what was wrong with the dog that required hospitalization, his wife dying suddenly of a rare rodent borne virus just after bringing the doghome, and the bodies being discovered a week or so later by (my understanding) a pest exterminator.
