The latest exhibit – a note written on hotel stationery found in the Nirvana frontman’s wallet at the time of his death in April 1994 – referencing his wife Courtney Love in less than flattering terms.
It says: "Do you Kurt Cobain take Courtney Michelle Love to be your lawful shredded wife..." It goes on to say, "even when she's a b**ch with zits and siphoning all (your) money for doping and whoring..."
The never-before-seen note was released by Seattle Police in response to public information requests from CBS News and will no doubt prompt speculation about the state of the pair’s marriage at the time of Cobain’s death.
But as CBS does point out: “The note may show the author, presumably Cobain, poking sarcastic fun at the marriage; or perhaps it reveals a deep-seated resentment towards Love about drugs, sex, rock and roll.. and money. One might even imagine two lovers penning the note together, fully aware of the scrutiny their relationship engendered.”
Indeed the note is at odds with Cobain’s handwritten suicide note which states: “I have a goddess of a wife who sweats ambition and empathy.”
Conspiracy theories over Cobain’s suicide continue to abound, as do accusations Love was somehow directly involved in her husband’s death.
Much gossip abounds about the couple’s marriage too – with some unfounded sources suggesting Cobain had been in the process of trying to arrange a divorce before he took his own life.
In an interview with Spin magazine in 2012, Love openly mused on where her late husband would have been had been alive today.
"We'd probably live on the Upper West fuckin' Side now and have three fuckin' kids," she said, adding: "We might even have a divorce, like both be on our third marriage. I don't fuckin' know. He might be a playwright, [or have] his latest show in MoMA [New York's Museum of Modern Art]."
Perhaps in anticipation of the upcoming anniversary of Cobain’s death, last month Seattle Police released previously unseen images showing drug paraphernalia at the scene of his death.
The images came from rolls of undeveloped film discovered by Detective Mike Ciesynski, who was reviewing the case.
The development prompted speculation Cobain’s death was being reinvestigated, but a police statement clarified: “There are no new developments, no new twists or turns in the case.
“He came upon this film, and that’s pretty much it. It is still a suicide.”
The images showed a cigar box filled with needles, a spoon and a lighter. Cigarettes, a pair of sunglasses and a crumpled banknote are also visible.
There were further pictures of Cobain’s body at the scene but they will not be released.
