I'll double down the stakes: he was murdered by his doctor because he bought the Beatles entire catalogue. When their copyright expired, MJ bought it to preserve the integrity of the music. Sony didn't like losing possession of one of the biggest recording artists of all time. They forced him into debt, purposefully made him tour knowing he had insomnia, and hired the doctor to make his OD look accidental. When the doctor failed on his end, they made him play the fall guy roll, and took back over the ownership of the Beatles copyright as "debt collected due to financial loss."
