Suicide bomber using a pipe bomb

Suicidal deaths caused by pipe bombs are rare. An 18-year-old man was found dead in a forest by hikers. In immediate proximity to the body, a crater was located obviously induced by a detonation. The postmortem examination revealed severe damage of the head, upper-body and both arms and hands along with the extensive presence of soot and dirt. Particularly noticeable were numerous "entry wounds" and the presence of five bullet like pieces of metal in the body. The young man had a history of drug abuse and psychiatric problems. On the basis of autopsy findings, the conclusions of the police investigation and psychopathological considerations regarding the victim's case-history, discussion centers upon the differentiation between suicide by self-explosion, homicide by explosion or death as a consequence of numerous bullet wounds followed by an attempt to burn the body. Also considered is the possibility of paranoid psychosis induced by cannabis use as a cause of suicide.     

A distant-range, suicidal shotgun wound of the back

The case being reported is one of a shotgun fatality with a thoracic back wound. A 23-year-old man was shot from a distance with trajectories going from back to front and on a nearly horizontal level. These findings observed in the autopsy could represent homicide, but scene investigation and police records were interpreted and it became clear that the case was suicide. Thus, this case shows that the determination of the manner of death requires a careful forensic investigation including autopsy findings, scene investigation, and reconstruction of the events.     

Motor vehicle-assisted ligature strangulation causing complete decapitation: an autopsy report

The victim, a 63-year-old prosperous businessman from Labasa, of the Northern Island (Vanua Levu) of Fiji Islands, was found completely decapitated in the early hours of morning in 2004. Initial police investigation did not reveal any history of any medical or family calamity. Further inquiry by the police revealed that on the previous day the deceased had visited all his friends and relatives, and his behavior was not out of the ordinary. The police suspected it to be a case of homicide. On visit to the scene, a completely decapitated body was found in a van on a downhill road. Tire marks were found on the road. A nylon rope was used for ligature strangulation. At autopsy, the decapitation wound of the head and the torso articulated well. The face was congested, and there was tongue bite. Wound margins were clear-cut, with well-demarcated abrasion and multiple imprints of the nylon rope on the neck. The upper one third of the larynx was attached to the head. No other injuries were found on the body. From the findings, it was obvious that asphyxiation was involved in the death before decapitation.     

Body Transportation after Homicides: Offender and Offense Characteristics

Body transportation is defined as moving the body of the victim from the scene of a homicide to another location. We analyzed data on 513 South Korean homicide cases with convictions to compare 104 homicides involving the transportation of victims’ bodies with 409 homicides that did not. Offenders who transported their victims’ bodies were significantly younger and more likely to be related to the victims and were less likely to use sharp instruments and more likely to use blunt instruments or strangle the victims than offenders who did not. Victims of homicide involving body transportation were more likely to suffer injuries to the neck and head and less likely to suffer injuries to the torso. Finally, offenders who transported victims’ bodies were more likely to have planned the offense and destroyed evidence. The present findings have practical implications for police investigations.     

Unusual circumstances in a fourfold complex suicide

Complex suicides are defined as suicides using more than one method, which may sometimes suggest homicide. We present the case of a 27-year-old man who killed himself by using four different methods. The man was known as a loner and sufferd from bipolar psychosis. An eyewitness saw him afire and falling out of a window on the 4th floor of a hotel. He was wearing a judo dress with the belt wound twice around his neck. He died in a hospital about two hours later. The autopsy showed signs of neck compression typical of (self)-strangulation, several stab and cut wounds in the thoracic and abdominal region from sharp force, extensive first- to third-degree burns caused by the effect of heat, contusions of internal organs, serial rib fractures and several bone fractures of the extremities as signs of blunt force. The CO-Hb value in the blood amounted to 7%; the other toxicological tests were negative. Death was found to be due to exsanguination from a deep stab wound in the abdomen and multiple trauma caused by the fall from a great height in the course of a suicide. Homicide could be excluded due to the circumstances of the case, which demonstrated again that both the medical findings and the investigation results of the police are indispensable for the differentiation between suicide and homicide.     

Secondary combined suicide viewed by the wife]

A 47-year-old man was found dead at the bottom of a wall outward the door of the cellar of his house. Preliminary physical examination at the scene of the death revealed a laceration of the scalp, an incised wound in front of the neck and several stab wounds in the left chest penetrating through the clothing. Questioned by the police his wife told that her husband who suffered from severe depression had inflicted the incised and the stab wounds himself, had made an unsuccessful attempt at self-strangulation and had finally jumped down from the wall beside the stairs declining to the cellar of their house. As the circumstances of the scenario were suspicious and as the pattern of injuries arose doubts concerning self-infliction homicide was taken into consideration as well. Autopsy showed additional hesitation marks adjacent to the left end of the incised wound in front of the neck. The stab wounds of the chest were restricted to the region of the heart and displayed only minimal penetration of the chest-wall, findings characteristic of self-infliction. As a consequence the manner of death could be determined as prolonged suicide, and exact reconstruction was possible with the help of the wife's testimony.     

Concealed homicidal strangulation by burning.

Compression of the neck, either with the hands or by a ligature, is not an uncommon method of homicide. Burning of the body to try to conceal the homicide may complicate the situation by making it difficult to interpret the findings. We hereby report two cases of homicidal ligature strangulation with extensive burning of the bodies. In both cases, external findings included the presence of a soft piece of fabric around the neck that, when removed, disclosed a portion of pale, unburned skin that vividly contrasted with surrounding areas. Osteocartilaginous lesions were present in only one case. Carboxyhemoglobin levels in both cases were very low, and the histopathologic examination of distal airways for soot particles was negative.     

Determinants of public confidence in police: An international perspective

Previous studies concerning public confidence in the police had primarily focused on demographic, attitudinal, and contextual factors in the United States. Little research, however, has used country-level variables to explain variations that exist across countries. As a result, this study examined the impact of country-level predictors (e.g., homicide rate and level of democracy) as well as individual-level predictors on public confidence in the police by utilizing data sets collected from three international surveys. Using hierarchical generalized linear modeling (HGLM) for the multinomial dependent variable, this study found a significant and negative relationship between homicide rate and public confidence in the police. People living in a country with a higher homicide rate reported lower levels of confidence in the police. Level of democracy was also found to be positively related to public confidence in the police. Of the individual-level variables, age and education were found to be significant predictors. A positive relationship was also found between political conservatism or personal satisfaction and confidence in the police. In line with attitudinal and contextual predictors, individuals with higher levels of acceptance toward deviant subcultures reported lower levels of confidence in the police. On the other hand, those who were more satisfied with their country's democratic development showed more favorable attitudes toward the police. The findings of this study implied that police organizations should put greater efforts toward the reduction of crime while protecting democratic values within a society.     

CIRCUMSTANCES IN SUPPLEMENTARY HOMICIDE REPORTS: VARIETY AND VALIDITY*

This paper presents a critical examination of homicide circumstances as reported in supplementary homicide reports (SHR). Different types of homicides can be distinguished by the circumstance codes and victim/offender relationship recorded on the SHR. Delineating murder by type invites analysis of this offense from a victimization perspective–homicides have much in common with nonlethal offenses. Different types of homicide present different policy problems to police. The paper also discusses various sources of error in SHR data, which must be recognized by researchers interested in theoretical or policy questions.     

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.     

THE IMPACT OF POLICE INVESTIGATIONS ON POLICE-REPORTED RATES OF GANG AND NONGANG HOMICIDES*

This paper is concerned with the utility of police-reported rates of gang violence, particularly important in an era which stresses officially determined rates of violence. The basic question is whether police investigation procedures have a major impact on the police designations of homicides as gang related, a question of causal order answerable only by the triangulation provided by multiple forms of data analysis. With minor qualification, the results suggest that“gang” designations of homicides reject characteristics of the incident settings and participants, that intrusion of investigative processes on reported gang versus nongang homicide rates was minimal, and that gang homicide rates reported by these departments could be used as reasonable criteria for evaluating program impact.     

Attitudes towards police use of consumer/private DNA databases in investigations

Consumer DNA products, such as databases that allow the public to explore familial relationships, have recently been used by police to assist in investigations. This has moved the collection of DNA used in criminal investigations away from the limitations of criminal databases and has opened up ethical concerns regarding privacy and consent. This study explored public attitudes and support towards police use of consumer DNA databases in investigations to assess whether different crime types or moral and attitude alignments influenced the level of public support of police using these consumer products. An international survey of 438 adults, using theory and scales pertaining specifically to retributive punishment and attitudes towards law, courts and police, found that moral alignment and attitudes did influence the level of public acceptability towards police usage of these techniques and that support did vary based on crime type. This research found that higher levels of public support was given for the most serious case types explored (sexual assault and homicide). Participant support for police access to private DNA databases by case type was as follows; 83.5% for sexual assault, 83.2% for homicide, 85.2% for identifying unidentified human remains, 62.8% for robbery and 58.9% for illicit drug related cases. Small to medium effects sizes were observed for these results. Although these findings provided context towards public attitudes, further research specific to international attitude differences and variance between serious crime types and public acceptability could further develop these findings.     

Differences in female and male involvement in lethal violence in Russia

Relatively little is known of the distributions of homicide event characteristics in non-Western nations in which women relative to men are involved. This article utilizes unique homicide narratives drawn from Russian court and police records to compare homicide victim, offender, and event characteristics by sex of victim and separately by sex of offender. Results from logistic regression show that homicides in which a female was the victim or offender were more likely to occur between intimates and to occur in the home, whereas homicides involving males were more likely to occur in a public place, to be alcohol-related, to involve a firearm, and to involve a victim and offender who did not know each other well. These results not only present an important first glimpse at women as homicide victims and offenders in Russia specifically, but also provide a point of comparison with findings from similar analyses undertaken in the West, and present further initial observations upon which to construct a cohesive theory about female involvement in serious violent events.     

The effectiveness of psychological profiles

Although psychological profiling of unknown offenders is becoming a popular media topic, there has been little research on the effectiveness of these profiles. In this study, surveys were sent to 95 police departments in the United States, asking participants to indicate if they use psychological profiles to solve crimes. The survey also asked whether the profile was helpful, and in what sense it was helpful. The results from this sample indicate that profiles are used mainly in cases of rape and homicide, and that police officers view profiles as an effective tool to guide interrogations of a suspect and to guide the criminal investigation but not necessarily to identify the suspect.     

Police shooting and criminal homicide: The temporal relationship

This study examines the temporal relationship between the incidence of police shooting and the incidence of criminal homicide for New York City between 1971 and 1975. The research finds that there is no temporal relation between the incidence of police shooting and the incidence of criminal homicide and concludes that the very strong and widely supported cross-sectional correlation between police shooting and criminal homicide is spurious, not causal.     

CAPITAL PUNISHMENT AND LETHAL ASSAULTS AGAINST POLICE

This investigation provides a multivariate analysis of the deferrent effect of the death penalty on the rate of lethal assaults against the police. Examining statelevel data for the period 1961 to 1971, we hypothesize a significant inverse relationship between the rate of police killings and (1) the statutory provision for capital punishment and (2) the execution rate of convicted murderers. Contrary to the deferrence hypotheses, no support is found for the argument that the provision and use of the death penalty provides an added measure of protection for the police. Rather, variation in police killings rates, like the general homicide rate, would appear to be largely a function of various sociodemographic factors.

Death notification

Death notification--informing the deceased's family of an unexpected death--is a singularly stressful task common to medical personnel, clergy, and police. We surveyed by questionnaire a group of 50 Los Angeles Police Department homicide detectives, 21 of whom were subsequently interviewed by telephone. The detectives stated that their initial apprehension stemmed from feeling unprepared. Identification with victims' families was common and compounded the stress. One prevalent worry concerned the possible reactions of the family upon hearing the news, especially the risk of a violent attack on the police officer. Several coping styles were recognized. Our findings suggest that the repetitive performance of this continuously stressful task may be a prominent and underappreciated contribution to occupational burnout.     

THE FEMALE HOMICIDE VICTIM

This study examines the ways that females meet violent death and the role that illegal drug use plays in precipitating such deaths. The sex role hypothesis and the transactional risk thesis are explored to help account for homicide victimization of women. Data were drawn from the records of the Medical Examiner's Office in Philadelphia. Records of all illegal drug using homicide victims were compared with a random sample of non-drug-using victims. Data included interviews with relatives of the deceased, autopsy reports, police and other records. Both hypotheses received support. The importance of these findings can only be assessed, however, when more is known about how sex role constellations work in drug-using groups
