Actually without knowing the autopsy results it is the opposite - very suspicious. 35 years old people don't just die at home. Let's hope the results will not be that he died of some kind of drug "overdose".
35 year-olds most certainly do die at home. The mechanism of death could have been something highly personal and highly embarrassing, nothing to do with drugs or conspiracies.
I once learned more than I bargained for when I asked too many questions at a friend's funeral. If his close family members don't want to elaborate on the circumstances surrounding his death, it is probably best not to press them.
To be clear, I wasn't making a comment about Barnaby Jack's death specifically. I have no idea what happened and if the family would like to keep it to themselves, I fully respect their wishes. I was just making an honest observation that whenever someone dies and people won't talk about it, that's always the first thing that pops into my head, particularly when there is a suggestion of embarrassment involved (which pertains to the person I was responding to, but not Barnaby Jack).
My brother died, unexpectedly, at 36. He'd had an apparently long running problem with prescription pills that nobody knew about. I had an aunt (sort of, she died before I was born) who was 25 and went to lie down in the bedroom because she felt unwell; she had an undetected congenital defect in her aorta and bled to death internally. My father in law died of a heart attack at 27 because he had congenital familial hypercholesterolimia. His elder brother died a year later by electrocution.
Young people do just die for unobvious reasons, both to the (comparatively) famous and the obscure.
If you hear hoof-beats, you'd expect a horse, not a zebra (unless you are on a Safari).
It's not that uncommon that 35 year old people die at home. Common causes are suicide, unintentional overdose, aneurysm (brain, AAA), arrhythmia, a fall.
