Only other thing I could think of would be a blood choke but that would require a slightly different hold than I saw in the little 2 minute clip. And he would have to maintain it pretty hard for a bit even after the dude goes limp and unconscious which I highly doubt but you never know.
probably drug related.
choking someone for a couple minutes then letting go soon after they're unconscious is not going to kill a normal healthy person.
people can hold their breath 2+ minutes pretty easily. actual brain damage takes 5+ minutes.
idk if the autopsy is ever going to be released

So yeah my money is on drugs at the moment.
UFC guys get choked out all the time and no one dies.
