It may have been almost three decades since his death Kurt Cobain, but there are many people who still do not believe that suicide was the cause of his death.

One of them is the author Ian Halperin, who claimed to have proof that Cobain had used heroin (70 doses were found in his system) when he was found dead in his home. He clarified that scientifically it makes no sense that the music star committed suicide.

“Cobain was murdered according to the evidence I have collected,” the author told the American newspaper “The US Sun”.

“He had 70 times the lethal dose of heroin in his system. Medical examiners say it’s impossible for anyone to take that much heroin for more than a second, let alone turn around, pick up a rifle and kill themselves. It is scientifically impossible that Cobain killed himself with the shotgun.

To be clear, the heroin was 70 times more than a normal person, who had not used before, could handle, and three times the amount that a user could handle.

I also write that there were no prints on the gun they found. The dead don’t wipe their tracks,” added Ian Halperin.
