The musician and frontman of the grunge band "Nirvana" Kurt Cobain did not commit suicide, but was murdered.

This was stated today by Canadian documentary film director and investigative journalist Ian Halperin, who invited Cobain's widow, Courtney Love, to take a polygraph test and dispel doubts that she killed him, NOVA reported.

As reported by the Sun, in an interview to promote his new book Case Closed: The Cobain Murder, Halperin said the polygraph test would help Courtney Love "clear her name" after nearly three decades of suspicion of Nirvana fans and the question of what really happened.

"The sentence should be changed from suicide to murder."

All of this relies on forensic evidence, new evidence that I dug up.

I'm not accusing anyone of murder, but I challenge Courtney to finally take a polygraph.

I will pay to clear her name.

If she passes the polygraph test, I'm going to rent a billboard in Times Square and write on it, 'Courtney Love is innocent,'” he said.

Halperin's 2009 book, Unmasked: The Final Years of Michael Jackson, was a #1 bestseller on the New York Times list on July 24, 2009.
