Official crime rates and victim surveys: An empirical comparison

This paper compares the Uniform Crime Reports (UCRs) to the results of the National Crime Survey (NCS). Six Part I offenses are used to form the basis for comparison across twenty-six large American cities. The two data sources are conceptually comparable. Empirically, the NCS reveals significantly higher rates for all offenses but auto theft. The two sources are compatible in that the UCR revealed the same distributional pattern as the NCS. Thus it was concluded that the UCR provides an accurate indicator of the relative occurrence of criminal acts.     

Ecological considerations in victim reporting to the police

A review of recent criminological literature suggests that different systems of social control operate across the urban-rural dimension. Specifically, it is expected that victims in urban areas will report crimes to the police at a higher rate than victims in surburban and rural areas. Moreover, it is anticipated that urban, suburban, and rural victims will have different reasons for not reporting the crime. In this paper these issues are examined empirically using the National Crime Survey victimization data. These data show that, contrary to theoretical expectations, the extent of victim reporting does not vary across the urban-rural dimension for the crimes of rape, robbery, assault, and personal larceny. Characteristics of the offense, notably seriousness, are shown to be more important in victim reporting than the extent of urbanization. In addition, these data indicate that victim residence in conjunction with type of crime and victim-offender relationship has an influence on the reasons selected by victims for not reporting the crime to the police.     

Cyanide poisoning: forensic toxicology observations in the study of 54 cases of fatal poisoning

The present study describes various observations made during the examination of 54 cases of lethal cyanide intoxication at the Institute of Forensic Medicine of the University of Zürich during a period of more than 40 years. Data pertain to the scene of death, the medicolegal inspection, the autopsy, the histological examinations, the chemical analyses, the various types of poisoning observed and the diagnostic criteria used. The intoxicated victims were mostly adults who had professional access to various cyanogenic compounds and had ingested them with the intention of committing suicide. Cases of accidental and criminal poisoning were rare. In spite of this fact, and although its frequency has not increased in the last few decades, cyanide poisoning has maintained undiminished importance.     

Hanging: suicide or homicide?

Death by Hanging: Suicide or Homicide. Six cases of homicidal hanging and murder presented as suicidal hanging are recorded. Suspension followed strangulation by ligature or throttling and head injuries in 4 cases. Distinction between homicide and suicide was easy in 5 cases: two of the perpetrators gave themselves up to the police, one committed suicide immediately after he had hanged his 15 year old daughter; in two cases tracks of blood, heavy injuries of the victims, and traces of robbery were obvious. Unless the victim is an infant or an adult person incapacitated by drink, disease, or drugs, or unless there are several assailants murder is difficult to accomplish. Distinction between murder and suicide may be impossible by an examination of the body alone. Detailed investigation of the scene, reconstruction of the position of the suspended body, examination of the rope, the knots, the direction of the fibres on the rope may serve to discover homicidal hanging. - Compared to suicidal hanging homicide has a frequency of about 1% in our autopsy material. However, we cannot estimate the number of obscure cases.
