For those that are genuinely confused, there’s two very important things you must know. The coroner is the job title for the guy who writes up what caused you to die. They do things like autopsies (when required), and they’re basically a doctor for dead people.
The other thing is the English idiom of “paying [someone] off”, which is basically a common way to not so subtley say that you’re bribing them.
So in plain language: there is an extremely good chance that my uncle bribed the coroner to ignore whatever he found on my uncle when he died and say he perished from natural causes. This normally implies something about self deletion and insurance, since insurance basically never pays out if you die by your own hands.
Is anyone still confused? Please let me know if you are and I can address any part of this that might not be crystal clear.
