Twenty years after Nirvana frontman Kurt Cobain was discovered dead in his Seattle home, police have released a note found in his wallet that was kept private until now.

The note, which was obtained by CBS, mocks the rock idol’s vows with his then-wife Courtney Love, adding further intrigue to the two’s marriage and how that and his personal life led to his demise.

It reads: "Do you Kurt Cobain take Courtney Michelle Love to be your lawful shredded wife," he wrote. "even when she’s a bitch with zits and siphoning all yr money for doping and whoring…"

The note is written on stationery from the Phoenix Hotel outside of San Francisco and is in stark contrast to Cobain’s presumed suicide note that calls Love a “goddess of a wife who sweats ambition and empathy.”

As well, Seattle Police have publicly released 34 photographs taken at the crime scene. See them in a gallery at the Seattle Police Department blotter website.

Last month, Seattle Police Department Cold Case Detective Mike Ciesynski reviewed the Cobain case. To prepare, he said he studied conspiracy documentaries, articles and TV shows about Cobain’s death.

"We knew with the 20th anniversary coming up and we knew there was going to be a lot of media interest," he said in a statement. "I've been a detective in homicide for 20 years and I've been in the cold case unit for 10 years. Most of the cases I work on, I look for something that wasn’t done [in the investigation] in the past."

The review confirmed the King County Medical Examiner's original determination that Cobain's death was a suicide, using a shotgun to shoot himself after taking what would have likely been a lethal dose of heroin.

Though it is unusual for police to reopen a case closed two decades ago, Ciesynski said in the statement that because of the case’s high profile, detectives put the Cobain file into storage: "There were so many conspiracy theories out there, it was good judgement on their behalf to hold to this."
