Now this is pure conjecture... 100% no proof... 100% no idea... but,
It wouldn't surprise me if there was at least one body buried in Hunter's past... doing that many drugs, with the types of groups he was running with, and especially overseas... well, let's just say, it's not unlikely.
Again, no proof... but if you've ever known, or been in the life yourself, everyone... and I mean everyone, knows someone that has died from the associated activities... And you're going to tell me the dude was banging eastern bloc sex trafficked hookers run by the mob, doing massive amounts of coke and heron... in places where the police can literally be bought for $100 bucks to look the other way?
Not saying it did, but wouldn't surprise me.
