Kurt Cobain was the lead singer of Nirvana. He began using heroin for medicinal purposes in his early career to remedy a stomach condition. He also struggled with depression and anxiety. Police reports say that he passed due to heroin overdose on April 5th of 1994. However, there is substantial evidence pointing towards foul play.
Tom Grant was hired by Courtney Love on April 3rd to help find Kurt. Over the course of his investigation, he noticed a great many discrepancies. He continues to investigate using his own time and money to seek justice in the matter. You can find more information on his website. There is a link below.

I have plans to visit Washington for a week in the summer. Aberdeen has established The Kurt Cobain Memorial Committe, whose mission is to "Memorialize Aberdeen-native Kurt Cobain...within Aberdeen city limits". The committee recently had "Come As You Are" added to Aberdeen's Welcome sign. They also have other community projects pending, including a memorial park and a youth center. The committee relies heavily on donations.
