Abstract
Introduction：
It is an illegal act to deprive or murder other’s life, so the crime of homicide is of utmost importance in criminal law to ensure personal legal interest. I collected the Forensic autopsy reports of homicide victims and tried to analyze the concentration and types of CNS inhibitors in toxicological results. Furthermore, I also analyzed the correlations between the CNS inhibitors and death. From the analysis of the ratio of CNS inhibitors used in homicide victims and the purpose of the perpetrator, I hope to provide more useful information to both the judicial and Hygienic branches of government, thus preventing the reoccurrence of similar death.
Steps and methods
I collected 571 cases performed forensic autopsy and reported to the Institute of Forensic Medicine, Dept of Justice from 2006 to May, 2013 from my working experience. After requiring the initial statistics from cases that are regarded as “homicide” or “possible homicide” by judicial investigation, I analyze the methods and motivations of the crime, and the influence of types and concentration of CNS inhibitors to the cause of death. I further analyze the contribution of the concentration of CNS inhibitors to the cause of death after studying the autopsy reports. I also compare the difference of the relation between CNS inhibitors and the cause of death among homicide and non-homicide groups to determine whether the CNS inhibitors are an aid to homicide or just an aggravation to the intent.
Result ：
There were 252 cases indentified as using CNS inhibitors in the aforementioned 571cases after detailed forensic autopsy. The ratio in every cause of death is as follows: 31.8% in the natural death（n=211）, 46.8% in the accidental death （n=173）, 46.43% in homicide victims （n=56）,61.5% in the suicide death（n=91）, and 62.5% in undetermined（n=40）. On the other hand, when studying the relation between the murderer and the victim, the percentage of using hypnotic sedative drugs with ethanol at the same time is 50%（5/10） in parricide , 38.7% （5/13）in acquaintances , and 10%（3/20） in strangers. When concerning whether violence was also used, there are 30% （3/10）in parricide, 84.6%（11/13） in acquaintances, and 75% （15/20）in strangers .
Conclusion：
Murder by strangers mostly resulted from impulse such as dispute after drinking. The methods in the scenario are often diversified and not necessarily including the use of CNS inhibitor. However, cases such as parricide or murder conducted by relatives, CNS inhibitors are often used and concealed by other more apparent factors such as burned charcoal or medication to mislead investigation. Therefore, forensic investigators have to be more cautious and perceptive in these cases because it not only concerns the interests of specific individuals, but the social perception and believe in justice.
