Reopening the Greenhouse: A Forensic Study Re-examines the Death of Kurt Cobain
In April 1994, Kurt Cobain, frontman of Nirvana and one of the defining voices of the grunge era, was found dead in the greenhouse above the garage of his Seattle home. The King County Medical Examiner ruled the death a suicide, citing a self-inflicted shotgun wound. The conclusion, supported by the Seattle Police Department, has remained the official account for more than three decades.
From the outset, however, questions lingered. Private investigator Tom Grant, hired by Cobain’s wife, Courtney Love, after the musician left a Los Angeles rehabilitation facility on March 31, raised concerns about the scope and handling of the investigation. Grant has long argued that key events in the days leading up to Cobain’s death were insufficiently examined, and that aspects of the case warranted closer scrutiny.
In 2025, that scrutiny took a new form. A paper published in the International Journal of Forensic Sciences, titled A Multidisciplinary Analysis of the Kurt Cobain Death, revisits the evidence using contemporary forensic methods. Drawing on bloodstain pattern analysis, firearm mechanics, wound trajectory reconstruction, toxicology, and document examination, the authors argue that the physical evidence may not fully align with the established conclusion of suicide. They stop short of definitive claims, but suggest that the possibility of homicide cannot be excluded.
Central to the study is the weapon itself: a 20 gauge Remington Model M11 semi automatic shotgun fitted with a Cutts compensator. The authors conducted experimental firings with a comparable firearm to examine how the weapon’s long recoil system behaves under different conditions. According to the original investigation, Cobain’s left hand was positioned on the barrel near the compensator at the moment of discharge. The study contends that such a grip could have interfered with the recoil mechanism, potentially preventing the ejection of the spent shell. Yet a spent casing was reportedly recovered at the scene. The argument is technically detailed, but rests on assumptions about hand placement and body position that cannot be definitively reconstructed.
The trajectory of the fatal wound is another point of contention. The autopsy described a contact or near contact shotgun wound entering through the upper palate. The study estimates the angle of fire at approximately 35 degrees. The authors note that self inflicted intraoral gunshot wounds are often recorded at steeper angles, while homicidal cases may present closer to perpendicular trajectories. Whether such comparisons are reliable, however, depends heavily on variables such as posture, movement, and positioning at the time of discharge. Without precise reconstruction, the significance of the angle remains open to interpretation.

Perhaps the most contested aspect of the study is its analysis of bloodstain patterns. Close range gunshot wounds to the head typically produce backspatter, biological material projected in the opposite direction of the bullet’s path. If Cobain had been holding the barrel near his mouth, the authors argue, such material might be expected on the hand. Available photographs, they claim, do not clearly show this pattern. Instead, they identify what they interpret as transfer staining, suggesting that the hand may have come into contact with blood after the shot was fired. They also point to blood inside the shotgun’s compensator vents alongside relatively clean areas on the outer barrel, raising the possibility of handling or wiping. These conclusions, however, are based on photographic analysis rather than direct examination of physical evidence, limiting their evidentiary weight.
The toxicology findings introduce further complexity. Cobain’s blood morphine concentration was recorded at 1.52 mg/L, with the presence of 6 monoacetylmorphine indicating recent heroin use. The official account holds that Cobain injected the drug, remained conscious long enough to put away the syringe, and then used the shotgun. The 2025 study questions whether such a sequence is physiologically plausible. The authors argue that an intravenous dose producing that level of morphine could have caused rapid sedation or unconsciousness, particularly in combination with diazepam, which was also detected. They also highlight a puncture wound on Cobain’s left forearm that they suggest may be inconsistent with the syringes reportedly found at the scene. Yet without detailed pharmacokinetic modelling or additional tissue analysis, the precise effects and timing of the drugs cannot be conclusively determined.
The suicide note, long central to the case, is also revisited. The study draws attention to longstanding concerns about the final lines of the note, which explicitly reference suicidal intent. Some handwriting analysts have noted stylistic differences between these lines and the main body of the text. The authors do not assert forgery, but argue that tonal and structural inconsistencies merit further examination. As with other aspects of the case, the absence of a comprehensive reanalysis of the original document leaves the question unresolved.
The study is careful to acknowledge its limitations. The authors did not have access to original physical evidence, several pages of the autopsy report remain unavailable, and much of the crime scene documentation has not been publicly released. No new laboratory testing was conducted, and the paper does not present direct evidence of third party involvement. Rather than offering definitive conclusions, it identifies areas where the available evidence may be incomplete or open to alternative interpretation.
Three decades on, the official ruling remains unchanged. Yet the emergence of new analytical frameworks highlights how forensic interpretation can evolve. Advances in imaging, bloodstain analysis, and biomechanical modelling offer tools that were not widely available in 1994. While such developments do not, in themselves, overturn established findings, they can prompt renewed examination of cases long considered closed.
The greenhouse above Cobain’s garage has become an enduring symbol, not only of a personal tragedy but of a cultural moment. His death continues to sit at the intersection of music history, addiction, and public myth. The 2025 study does not resolve the questions that have surrounded it. Instead, it underscores their persistence.
For now, the official conclusion stands. But the debate, forensic, cultural, and deeply human, remains open.
