Was Kurt Cobain Murdered?

This question has been floating around for several years, About the Nirvana singer.
There are many facts pointing towards murder. Fact one: 225 MGS of Heroin was found inside of his body, That is enough to kill, or put a person in coma within seconds. If he was out cold, or already dead, how could he possibly shoot himself? Also, there wasn't any gun or bullet evidence on the scene. It was already 'swept clean'. One of the suspects is Courtney Love, the singers wife. Or soon to be ex-wife. Also, Eldon Hoke said Courtney offered 50,000 dollars for him to kill Kurt. He was tested with a lie detector, and it showed he was 99.7% telling the truth. A motive for her to kill him was that he wanted to divorce her, And take custody of their child. Its also said he was taking steps to remove her from his will. We will probably never know the truth, But i just wanted to share that with you guys. But ever since he's been dead, The foo fighters formed! There's my favorite song of theirs over somewhere. haha, So, have a good day. And keep on.. doing what you do..
