Journalists Ian Halperin and Max Wallace published their investigation of any possible conspiracy surrounding Cobain's death in their 1999 book "Who Killed Kurt Cobain?". Halperin and Wallace argued that, while there was not enough evidence to prove a conspiracy, there was more than enough to demand that the case be reopened. A notable element of the book included the journalists' discussions with Tom Grant, who had taped nearly every conversation that he had undertaken while he was in Love's employ. Over the next several years, Halperin and Wallace collaborated with Grant to write a second book, 2004's "".
