These 3 scenarios are the only explainations of what really happened.
In my mind, there are only 3 possible scenerios for what really happened. Suicide, assisted suicide, or murder. I will explain each.
Suicide: Kurt injected himself with a large dose of heroin so he wouldn't feel a thing when he pulled the trigger of the shotgun.
Assisted suicide: Kurt had someone there with him to make sure it happened and may have helped with the injection and/or shotgun.
Murder: Somone was there with Kurt and injected him with too much heroin without him knowing. Placed the shotgun in his hand and pulled the trigger for him.
I don't see any other scenarios other than these 3. What do you think?
I'm not going to point fingers that there was definitely foul play involved/murder. There are inconsistences and evidence to suggest possible foul play/murder. I could maybe look past some or most of it (the hand writing practice sheets are weird among other things) but then you have the investigation which was done very poorly and closed the same day. All of the important evidence (Kurt's body, the shotgun, and the green room itself) has been destroyed. Plus, there was motive as was mentioned in this movie. $$ With him deceased she gets the whole thing. Bottom line, if the investigation was done more thoroughly and properly (which for one of the biggest icons/legends in music history, it definitely deserved to be), this would not be as much of a discussion as it is today. R.I.P. Kurt Cobain.
