Well there is plenty. The most recent one that is weird is the death of Mac Miller. Some says it was accidental, some that it was the drug seller that hated him and sold him shitty stuff intentionally, some said it was suicide. Etc..
However, I cant see anyone taking as much different drugs he took at once, at those doses, and suicide is definitely out of context for many reasons even though he used and probably still was depressive. And even the second one feels odd.
