It was 25 years ago today that Kurt was murdered.
He mastered music and a sound which reflected a the consciousness of a culture. The music is immortal.
He could easily have lived without the money. He loved his daughter and would not abandon her.
Some more reasons come to light why it could not be suicide:
A few weeks before someone roofied Kurt in Italy which nearly killed him. That was very likely a failed murder attempt.
Some have suggested that it mentally impaired him, triggering suicide. Seems like misinformation to me. All of the facts point to murder, not suicide.
Kurt had a place he rented near his known H supplier, when he was using. But at the time of his murder, he was clean and had been recovering from the OD on roofies, which someone slipped him. This is undoubtedly why he escaped from the rehab in CA. Why would you go through rehab if someone roofied you?
He would have known someone was trying to kill him. He was concerned about it and had Dylan buy the shotgun for protection! But like a lot of firearms bought for protection, it wound up getting used against him.
Now, imagine the scenario when he was murdered. He knew them. I think at least 2 people were there. He would not willingly shoot a 3x leathal dose. He was experienced. Someone injected him. Why would he allow it? Perhaps there was a conversation and he was held at gunpoint, the life of his daughter threatened. At first he didnt resist, but then seeing how much was being injected he became aware. What could he do? His own shotgun in his face, while someone else finds his vein. Whatever words... it was happening fast. The needle, he looks, sees the dose, just as it plunges in he lurches forward, scaring the shotgun holder and it goes off blasting K in the face, throwing him back. They take a moment, roll his sleeve down, clean up the needle kit, wipe the shotgun, putting it down near him.
In this scenario, he wasnt supposed to be shot. It was supposed to look like he just od'd. But he resisted just enough at the last second.
The alternative, if it wasnt K's body... someone went through a similar scene in his place. The difference to me is that with a double, the shotgun blast would be to damage the face and head allowing for a false identification.
Another thought is that he was tricked by people very close to him. Someone whom it would not bother him to be holding or playing with his shotgun, while someone else looks at his arm and offers to share a syringe with him. See if the syringe were filled for 2 or 3 people to share, he might not have been immediately alarmed. He might have found it strange, and being conflicted about using. A temptation, with very close trusted friends. He gets the first dose, he thinks, but he really gets it all. See no time to pull a trigger, but time to jerk forward causing the person to pull trigger.
