2.) INCAPACITATED OR DEAD BEFORE GUNSHOT: Large overdoses of heroin by heroin addicts are a phenomenon which is well understood. Research clearly shows that an overdose in the range of that received by Cobain would lead to immediate and complete incapacitation and/or immediate death.

3.) OTHER FACTORS ENSURED OVERDOSE LETHALITY: The 1.52 mg/L blood morphine level does not compensate for the presence of diazepam, or Cobain's low body weight, both of which are well proven to substantially increase the lethality of the heroin.

4.) CASE UNPARALLELED IN SUICIDE & OVERDOSE REPORTS: A review of 3586 suicides, including 760 violent suicides, shows no case involving both a gun and narcotic overdose of any kind, supporting theories regarding the absence or extreme rarity of violent suicide among addicts.

5.) CASE CONSISTENT WITH HOMICIDE PATTERNS: A review of cases involving homicides shows many similarities with patterns in the Cobain case.

6.) OTHER EVIDENCE INDICATES HOMICIDE: Officially acknowledged evidence exists which indicates the possibility of homicide, including a misleading missing persons report, postmortem credit card usage, handwriting discrepancies on the "suicide" note, and the lack of legible fingerprints on the weapon. It appears the police were prejudicially in favour of a suicide ruling, and that the coroner was involved in a conflict of interest predisposing him towards this major discrepancy in the evaluation of his findings.

7.) CONCLUSION: HOMICIDE: The evidence indicates that a massive intravenous dose of heroin, and possibly a benzodiazepine, was administered to Cobain. The final of the two known injections incapacitated and/or killed Cobain, and the gunshot is evidence of a homicide staged to look like a suicide. The case should be re-opened by an independent investigatory body.

INTRODUCTION

Kurt Cobain's untimely death is admittedly a morbid subject. This essay is intended solely to contribute to the efforts of thousands of Cobain admirers and others who seek to put an end to the copy-cat suicides, and to discover the truth behind this horrible tragedy. Estimates from 1995 listed over 150 acknowledged copy cat suicides, some of which are described in Appendix B. Concerns regarding potential lawsuits from bereaved parents against the Seattle Police Department has been suggested to be a factor in their determination to keep the case officially closed unless "new evidence" comes forward. One such piece of new evidence is the following re-interpretation of the officially released evidence. The official time of death is unknown, but is estimated as occurring no later than towards the evening of Tuesday, April 5th, and the body was found Friday, April 8, at 8:40 a.m. This will be the starting point for the following research and observations which attempt to present the facts supporting the claim that Cobain was incapacitated or dead at the time he supposedly shot himself, a situation which would obviously completely eliminate the possibility of suicide. The essay is somewhat technical, so efforts have been made to simplify and explain these matters for those who are not familiar with the scientific nature of this research. Additionally, some are details of the Cobain case are presented for those who are unfamiliar with the case in general.

1.) TRIPLE MAXIMUM LETHAL DOSE
EVEN FOR SEVERE ADDICTS:

1.52 MG MORPHINE PER LITRE OF BLOOD
Cobain's death in April, 1994 led to wide media coverage, and it was soon revealed that his blood morphine level was 1.52 mg per litre (mg/L). One biographer mistakenly claimed that Cobain "injected" 1.52 mg of heroin. The figure 1.52 mg actually refers to the level of drugs found in Cobain's blood, not the amount he originally injected. This can be seen in other reports, both biographical and mass media, where the 1.52 mg level is sometimes further described as "per litre of blood" or "triple the lethal dose," usually with subsequent notes that an addict has higher tolerance. Cobain would have needed to inject much more than 1.52 mg of heroin to help even the most mild headache. Additionally, the Seattle Police Department reported that a cigar box of drug paraphernalia was beside the victim, including pieces of what appeared to be black tar heroin, generally regarded as Mexican in origin. Also, according to the Seattle Police Reports, two puncture marks were found on Cobain's body, one in each arm, in the inside crooks of the elbow region.

TOLERANCE HAS A WELL DEFINED LIMIT
The fact that there is "higher tolerance among addicts" is commonly misunderstood. This concept is evoked apparently as an attempt to describe how it could be remotely possible that Cobain was alive and functioning well enough to fire a shotgun, despite the otherwise triple maximum lethal dose. The "1.52 mg" figure refers specifically to the morphine per litre of blood. No doubt exists that a blood level of 1.52 mg of morphine per litre represents just a little bit over three times the maximum lethal dose, but the implications of this fact are not well understood.

WHAT IS THE LETHAL DOSE OF HEROIN?
Table 2, below, shows that the lethal dose range of intravenous heroin is generally regarded as 10 mg to 12 mg. Sometimes even a tiny dose can kill, so the lethal dose of intravenous heroin can go as low as 3 mg, possibly even lower. Some people get confused and think that high variability in the minimum lethal dose means that a similar variability exists for the maximum lethal dose. The most serious heroin addicts will die with virtual certainty with much less than a dose of 75 mg to 80 mg of heroin. After studying many hundreds of such cases, it is clearly established that 75 mg to 80 mg is the maximum lethal dose for even the most severe heroin addicts. Note that in a low tolerance person, in an average hospital setting, a small effective therapeutic dose of intravenous heroin is only 3 mg to 4 mg. The important thing to note here is that the problems associated with establishing a "lethal dose" for intravenous heroin primarily relates to the problem of establishing a "minimal lethal dose," i.e. the smallest amount of heroin which will kill. The "maximum lethal dose," i.e. the highest dose of intravenous heroin a severe heroin addict can withstand without immediately collapsing into a coma and/or immediately dying, is very well documented. The blood morphine level of 1.52 mg per litre found in Cobain's body represents a heroin dose which is substantially higher than this well established maximum lethal dose.
