African-Americans and serial homicide

African-Americans are usually over-represented among offenders arrested in “normal” homicide cases, making up a considerably larger proportion than would be expected from the Black presence in the population at large. Among serial murderers, however, African-Americans are much less in evidence—perhaps one-fifth or less of known American serial killers are Black. It may be that African-Americans are in fact less involved in serial murder activity than are Anglo Whites or Hispanics; but it must also be asked whether this is simply an impression gained from the ways in which serial murder activity is identified and investigated. For a number of reasons, law enforcement agencies might be less likely to seek or find evidence of serial murder activity where the victims are Black. As homicide is primarily an intra-racial crime, this would then mean that Black serial killers would be far more likely to escape detection.     

DETERRENCE OR BRUTALIZATION? AN IMPACT ASSESSMENT OF OKLAHOMA'S RETURN TO CAPITAL PUNISHMENT*

On September 10, 1990 Charles Troy Coleman was put to death by lethal injection at the Oklahoma State Penitentiary. Coleman's execution was the first in the state in more than 25 years, generating significant media coverage and providing a unique opportunity to assess the impact of the state's return to executing capital offenders. Interrupted time-series analyses are performed with weekly data from the UCR Supplemental Homicide Reports for the state for the period January 1989 through December 1991. Analyses are performed for the total level of criminal homicides and homicides disaggregated into two types of murder–felony murder and stranger homicides–testing hypotheses that predict opposing impacts for each type of homicide. As predicted, no evidence of a deterrent or a brutalization effect is found for criminal homicides in general. Similarly, the predicted deterrent effect of the execution on the level of felony murders is not observed. Evidence of the predicted brutalization effect on the level of stranger homicides is observed, however. Supplementary analyses on further offense disaggregations continue to support these initial findings and permit a more coherent interpretation of the results.     

Domestic Homicide: Neuropsychological Profiles of Murderers Who Kill Family Members and Intimate Partners

Domestic homicide is the most extreme form of domestic violence and one of the most common types of homicide. The objective was to examine differences between spontaneous domestic homicide and nondomestic homicide offenders regarding demographics, psychiatric history, crime characteristics, and neuropsychological status, utilizing neuropsychological test data from forensic examinations of 153 murderers. Using standard crime classification criteria, 33% committed spontaneous domestic homicides (SDH) and 61% committed nondomestic homicides (NDH). SDH offenders were more likely to manifest psychotic disorders, but less likely to be diagnosed with antisocial personality disorder or to have prior felony convictions. SDH offenders manifested significantly worse neuropsychological impairments than NDH offenders. The mean number of victims was lower for the SDH than the NDH group and only 14% of SDH offenders used a firearm, whereas 59% of NDH offenders used a firearm. These findings corroborate the notion that spontaneous domestic homicide may represent a discernible criminological phenotype.     

Profiles in the offending process of nonserial sexual murderers

The aim of this study was to investigate specific pathways in the offending processes of nonserial sexual murderers and to examine possible relationships with different precrime, per-crime, and postcrime factors. Included in this study were 36 offenders who have committed at least one sexual murder against a female victim and they were classified using cluster analysis. Participants using the sadistic pathway planned their offenses and used physical restraints during the offenses. Furthermore, they mutilated and humiliated their victims. Finally, they hid the bodies of the victims. Participants using the anger pathway had not premeditated the homicide. Mutilation, humiliation, and physical restraints were less predominant with these participants than with those using the sadistic pathway. Moreover, these offenders were more likely to leave the bodies at the crime scenes after the killings occurred. These two profiles are compared with empirical studies addressing sexual homicide.     

Gender-specific risk factors for intimate partner homicide--a nationwide register-based study

The present study examined gender differences in intimate partner homicide (IPH) and offender characteristics with the focus on putative gender-specific risk factors in a nationwide consecutive sample of homicide offenders. Data on all offenders (N = 642; 91 females, 551 males) convicted of homicide and subjected to a forensic psychiatric examination in Finland were obtained for the years 1995 and 2004. IPH offenders, 39 female and 106 male, were compared for risk factors with female and male offenders whose victims were not spouses. The forensic psychiatric examination reports were retrospectively analyzed, and the Hare Psychopathy Checklist-Revised (PCL-R) was rated. Significant gender differences were found in four risk factors: employment, intoxication of victim, self-defense, and quarrel, mostly related to alcohol as a factor of the offense. The findings support the notion that female IPH is linked to defensive reactions resulting from prior abuse, and that IPH offenders resemble the general population more than offenders of other types of homicide.     

Young women and gang violence: Gender,street offending,and violent victimization in gangs

Drawing on multiple data sources in St. Louis, this article examines how gendered situational dynamics shape gang violence, including participation in violent offending and experiences of violent victimization. Combining an analysis of in-depth interviews with young women in St. Louis gangs with an examination of homicide reports from the same city, we find that young women, even regular offenders, highlight the significance of gender in shaping and limiting their involvement in serious violence. They use gender both to accomplish their criminal activities and to temper their involvement in gang crime. Consequently their risk for serious physical victimization in gangs is considerably less than young men's. St. Louis homicide data collaborate these qualitative findings. Not only are young women much less likely to be the victims of gang homicide, but the vast majority of female gang homicide victims were not the intended targets of the attack. In contrast, homicide reports suggest that the majority of male gang homicide victims were the intended targets. We suggest that gendered group processes and stratification within gangs are key factors explaining both violent offending and victimization risk in gangs.     

Journey to murder: examining the correlates of criminal mobility in sexual homicide

Although the empirical research on the journey to crime seems to indicate that most crimes are committed close to home, only a few studies have specifically examined the journey to crime in cases of sexual homicide. Using a sample of 214 sexual homicide cases, the current study investigates, using logistic regression, offenders who travel during the crime to those offenders who commit their crime, all at the same location. Current findings suggest that sexual murderers who engage in intra-crime travel tend to use a vehicle in the commission of their offence, target adult victims who are involved in the sex trade and move the body post murder.     

Injuries inflicted on homicide victims: A longitudinal victiminologic study of lethal violence

For the purpose of studying homicidal violence from a victiminologic point of view, we have examined the number and nature of injuries inflicted on homicide victims examined at the Department of Forensic Medicine in Stockholm during the periods 1976–1978, 1986–1988 and 1996–1998. Evaluation of the total number of injuries (both lethal and non-lethal) revealed a break in the earlier trend during the last of these periods, which demonstrated a clear increase in the number of injuries probably caused by intense and prolonged violence. Thus, there were 14 victims with 40 or more injuries (the maximum being 101 injuries) in the 1996–1998 period, whereas there was only one such victim in each of the two earlier periods. Furthermore, the proportion of victims exhibiting multiple lethal injuries was greater during the last period than during the two preceding periods. These findings indicate a general enhancement in the level of aggression exerted by violent offenders, as well as an increase in the number homicide victims with injuries apparently inflicted by acts of aggression characterized by outrage.     

When is violence planned?

We examine what types of violent offenses tend to be planned using self-report data from a nationally representative sample of state and federal inmates. We find mixed support for the idea that predatory offenses are more likely to be planned than dispute-related offenses. As expected, robbery offenders are much more likely to report that they planned their crime ahead of time than homicide and physical assault offenders. However, sexual assault offenders are no more likely to report planning than homicide offenders. We also find mixed support for the idea that domestic violence-the supposed crime of passion-is less likely to be planned than violent offenses involving strangers. Finally, we find substantial demographic variation depending on type of crime. Robberies involving offenders of lower socioeconomic status and homicides and assaults involving African American offenders and victims are less likely to involve planning.     

Do Gang Members Commit Abnormal Homicide?

Gang membership is a robust correlate of homicide offending and victimization, but little is known about the association between gang status and various abnormal forms of homicide (e.g., multiple-victim homicide, sexual homicide, and abduction homicide). The current study utilized data from a large sample of 618 male convicted murderers to empirically examine gang status and diverse forms of homicide perpetration. Gang-involved offenders were nearly three times as likely to commit a normal homicide characterized as a single-victim murder. However, gang members were 64 % less likely to perpetrate multiple-victim murder. In other models, gang status reduced the likelihood of sexual homicide by 75 % and reduced the likelihood of abduction homicide by 56 %. These findings present an anomaly in the gang-homicide literature, and suggestions for additional research are offered.     

Medico-Legal Evaluation of Adolescent Parricide Offenders: Thirty Nine Cases from Turkey

Parricide which is defined as the murder of one’s parents is a rare event. We describe a consecutive series of adolescent parricide offenders referred to the Council of Forensic Medicine for medico-legal evaluation. Majority of the adolescent parricide offenders were male with a frequency of 79.5%. Age of the offenders ranged from 12 to 18 years old with a median age of 15.13. The majority of the victims were the fathers of the offenders (27; 69.2%). Firearms and cutting devices were the most frequently used weapons. The history of abuse in the family as a motive for the murder was detected in 51.2% of the offenders. The major abuse type was physical abuse. There was no history of psychiatric disorders in the majority of the offenders (37; 94.9%). After the medico-legal evaluation of the adolescent parricide offenders in the Council of Forensic Medicine, psychiatric disorder was diagnosed only in 4 offenders. Schizophrenia was the final diagnosis in 3 cases and paranoid disorder (otherwise unclassified) in only 1 offender. Our study confirmed the frequency of mental illness among adolescent parricide offenders to be very low when compared to adult offenders. Adolescent parricide offenders differ from the other perpetrators particularly in terms of motives of the murder and psychiatric illnesses. Abuse in the family seems to play an important role in these murders. Therefore, it is extremely important that individuals in the legal, criminal justice, social work, psychology, educational and other professional communities be more conscious and informed of child maltreatment and family violence and more research is essential in understanding and preventing adolescent parricide offenders.     

An Empirical Study of Rape in the Context of Multiple Murder

In recent years, multiple homicide offending has received increased research attention from criminologists; however, there is mixed evidence about the role of rape toward the perpetration of multiple murder. Drawing on criminal career data from a nonprobability sample of 618 confined male homicide offenders selected from eight U.S. states, the current study examines the role of rape as a predictor of multiple homicide offending. Bivariate analyses indicated a significant association between rape and murder charges. Multivariate path regression models indicated that rape had a significant and robust association with multiple murder. This relationship withstood the confounding effects of kidnapping, prior prison confinement, and prior murder, rape, and kidnapping. These results provide evidence that rape potentially serves as a gateway to multiple murder for some serious offenders. Suggestions for future research are proffered.     

Association between homicide injury severity and benzodiazepine influence

There are case reports of offenders inflicting excessive injuries on their victims when under the influence of benzodiazepines. However, the potential association between benzodiazepine influence on the offender and victim injury severity in a general homicide population has not been studied. We investigated associations between offender positive testing for benzodiazepines or z-drugs (zolpidem, zopiclone and zaleplon) and victim injury severity. Data were drawn from 95 Swedish homicide cases from 2007–2009 in which offenders had known toxicology. There were no significant differences in injury severity between cases in which the offender tested positive vs. negative for benzodiazepines/z-drugs. Thus, the findings do not support the hypothesis that there is an association between benzodiazepine influence on the offender and victim injury severity in a general homicide population.

Key points

• Some previous studies have linked benzodiazepines to aggression, violence and excessive homicide injuries.
• The present study analysed the association between homicide injury severity and benzodiazepine status of the offender.
• Offenders who tested positive for benzodiazepines did not inflict more severe injuries on their victims.
• These findings do not support the hypothesis that benzodiazepine influence generally causes offenders to inflict more severe injuries on homicide victims.

     

FELONY MURDER AND CAPITAL PUNISHMENT: AN EXAMINATION OF THE DETERRENCE QUESTION

A proper test of the deterrent effect of the death penalty must consider capital homicides. However, the criterion variable in most investigations has been total homicides—most of which bear no legal or theoretical relationship to capital punishment. To address this fundamental data problem, this investigation used Federal Bureau of Investigation data for 1976–1987 to examine the relationship between capital punishment and felony murder, the most common type of capital homicide. We conducted time series analyses of monthly felony murder rates, the frequency of executions, and the amount and type of television coverage of executions over the period. The analyses revealed occasional departures (for vehicle theft and narcotics killings) from the null hypotheses. However, on balance, and in line with the vast majority of capital punishment studies, this investigation found no consistent evidence that executions and the television coverage they receive are associated significantly with rates for total, index, or different types of felony murder.     

Homicide–Suicide in Cuyahoga County,Ohio, 1991–2016

Research on homicides followed by suicides has relied heavily on small samples and relatively short time spans of data. This study helps to fill this gap by examining 26 years of homicide–suicide data from Cuyahoga County, Ohio, between 1991 and 2016. The main data source for the study is medical examiner files. Analyses of the data indicate the rate of homicide–suicide in Cuyahoga County is consistent with other studies but fluctuates considerably across years studied. The majority of victims are female while perpetrators are overwhelmingly male. Black people are overrepresented as victims and offenders. Use of drugs and/or alcohol leading up to the incident is common among perpetrators. Both the homicides and suicides were overwhelming committed with firearms. When comparing our results to the typology of murder–suicides developed by Marzuk, Tardiff, and Hirsch (JAMA 1992;267:3179), we find amorous jealousy is a significant motivating factor in a many cases, including those involving nonintimate partners. Our findings underscore the importance of widespread use of lethality assessment instruments.     

Female murderers in a southern city, 1975–1992

A study of a population of 36 females arrested for homicide in a southern, nonurban city from 1975 to 1992 was conducted using both qualitative and quantitative data. The study explored the demographic, social, legal, and offense characteristics of female homicide offenders as well as events leading to the murder. The profile of female homicide offenders in a southern, non-urban setting that emerged from this study is supportive of earlier studies focusing on female homicide offenders in large urban areas.     

Assessing the interaction between offender and victim criminal lifestyles & homicide type

Purpose

This study examined the interaction between homicide victim and offender criminal lifestyles and the situational characteristics of homicides that occurred in the city of Newark, New Jersey from 1997 through 2007. Three research questions were explored: (1) what are the lifestyles exhibited by homicide victims and offenders; (2) are there different types of homicide actors (i.e., victim and/or offender) based on their criminal lifestyle; (3) do varying homicide actor (i.e., victim and/or offender) types influence the characteristics of homicide incidents?

Methods

Five hundred and thirteen homicide incidents was used to answer the three research questions. Hierarchical Agglomerative Cluster and Logistic Regression Analyses were employed to answer the research questions.

Findings

The findings showed that criminal lifestyles were indeed very common among homicide victims and offenders, and that they resemble each other. The findings also showed that there were two types of homicide victims and offenders, and that these types influenced the etiology of homicide incidents.

Conclusion

Overall, the results suggest that researchers and practitioners should take into account the criminal lifestyles of potential victims and offenders when tailoring homicide prevention strategies.     

Criminal history and social disadvantage as predictors of the severity of violent offending

ABSTRACT

Lethal violence is often seen as the tip of the iceberg and homicide perpetrators are seen as manifesting the most extreme number of various risk factors. This article explores whether that is the case. Using a unique data set combining data from several administrative registers with a nationally representative sample of different types of police-reported violence committed during 2010–2011 (N = 26,303 offenders) in Finland, we compare the offenders of five different types of violence (minor assault, assault, aggravated assault, attempted homicide, and completed homicide). In addition, we examine the association between the severity of violence and prior criminal history and different types of strain. The results give partial support to the hypothesis: the more serious the violence, the more crime prone and socially disadvantaged the offender. Yet, lethal offenders do not stand out alone; the division, rather, appears to be between offenders of serious (aggravated assault, attempted homicide, completed homicide) and less serious (minor assault, assault) forms of violence.     

“Undoing” (or Symbolic Reversal) at Homicide Crime Scenes

A closed case file review of a nonrandom national sample of 975 homicides disclosed 11 cases (1.13%) of undoing, wherein offenders engaged in crime scene behavior that has been considered an attempt to symbolically reverse the murder. The frequency of the various methods of undoing involved the use of blankets to cover the victim's body (55%), positioning the body (55%), use of a bed or couch (42%), washing the body (36%), using pillows (36%), as well as removing clothing and adding other types of adornments (27%). Ten of the 11 offenders were male, and one was female; all 12 victims were female. Ten of the 12 victims were family members or relationship intimates. These findings are consistent with prior reports which concluded that the motivation for undoing behavior is an attempt to compensate for guilt or remorse for having committed the homicide.     

Psychopathic traits in Finnish homicide offenders with schizophrenia

There is a paucity of studies examining psychopathy in comparable samples of violent individuals with and without psychotic illness. The main goal of the study was to assess the prevalence and nature of psychopathic traits as measured by PCL-R among Finnish homicide offenders with schizophrenia. Further, the impact of co-morbid psychopathy on the homicidal incidents, as well as the associations of psychopathy and offender background factors, among offenders with schizophrenia was investigated.A retrospective study was performed using extensive forensic psychiatric evaluation reports and crime reports as sources of information. The sample consisted of 72 homicide offenders with schizophrenia and 72 controls without psychotic illness.Psychopathic features were prevalent among Finnish homicide offenders with schizophrenia, although for the most parts to a lesser extent compared to other homicide offenders. Like non-mentally ill psychopathic offenders, offenders with schizophrenia and many psychopathic traits are likely to present early starting problems in many areas of life and they also commit homicides that resemble other psychopathic offenders' in their choice of victims, intoxication and post-offense behavior.The observed prevalence of psychopathic traits highlights the importance of psychopathy assessment among violence-prone individuals with schizophrenia. In most respects, offenders with schizophrenia and high levels of psychopathic traits seem to be similar to psychopathic offenders without psychotic illness, which has implications for early intervention and management.
