Reddit mentions of Who Killed Kurt Cobain? The Mysterious Death of an Icon

He had something like 4 times the lethal dose of heroin in his body, even with a huge tolerance so he wouldn't die he would not be able to balance on one foot and pull the trigger with his other. They also found him with his shoes on, which makes it pretty impossible to pull a trigger. The door to the garage attic where they found him locked from the inside, so someone could have locked the door and pulled it closed behind them. They found a note in Courtney's bag that looked like she was practising Kurt's handwriting with sentences from the suicide note they found on him. Courtney had an alibi but I believe she set it up. There are other things that point to murder that I cant think of right now.

It just all seems pretty fishy to me. I read a book about it once, but I can't remember what the name was.

edit: it might have been this one but icr, there are several of them.

If you're interested more information can be found here, the the website of Tom Grant, the PI hired by Courtney to find Kurt who eventually concluded Cobain was murdered and she was at the least heavily involved. Just hits the main points, and has rather revelatory recordings of him with Courtney and her entertainment attorney Rosemary Carroll.

If that at all makes you curious, there's more information including police report pages here along with some unanswered questions.

If you're still interested, the two books written by Ian Halperin and Max Wallace are also pretty well done; they conclude Cobain was murdered, but that there isn't enough evidence to implicate Courtney. Just (in my opinion) an objective analysis of everything, including their own critique and criticisms of Grant.

*Forgot about this documentary. Also hits all the main points, not bad, but Soaked in Bleach looks like it is going to be a lot better.
