The note was released after Seattle Police Department (SPD) decided to review internal files regarding the rock star's death, reported CBS News.
Along with the note, the SPD also released dozens of never-before-seen photos from the scene where Cobain's body was found, along with a report on the re-examination of the rockstar's suicide file.
On April 8, 1994, when police arrived to find Cobain dead at his Seattle area home, this hand written note was recovered from his wallet. It served as a prime evidence and was never made public.
The note that was kept secret until now, promises to add fuel to the death of the rockstar and the role his famously troubled personal life and marriage played in his demise.
The note is written on stationery from the Phoenix Hotel, located on the outskirts San Francisco and confronts a much known note in which he calls Love, "goddess... Who sweats ambition and empathy."
