Applying social learning theory to childhood and adolescent firesetting: can it lead to serial murder?

Despite the fact that serial murder has existed for centuries, it has been given little academic attention in the social science literature. Existing studies have primarily examined the motivational factors involved in the commission of serial murder. However, research examining the childhood and adolescent backgrounds of serial murderers is scant. Based on three case studies of serial murderers, this study contributes to the existing literature by exploring the possible link between childhood and/or adolescent fire setting and adult serial murder by applying social learning theory.     

Inside the mind of the serial murder

This article approaches a position of delving into the thoughts of those who commit murder serially. The information comes from a variety of sources which include research literature, theory examination and most importantly, serial murderers themselves. More than 400 cases of serial fatal violence as well as interviews with incarcerated serial killers were utilized. Important issues such as locus of motives, expected gains, victim selection processes, planning of the event, the murder event itself, and organization and disorganization of the kill are also discussed. While admitting that serial killers have never been rehabilitated, a call is directed toward a better understanding of the mind of the serial murderer.     

Examining the relationship between childhood animal cruelty motives and recurrent adult violent crimes toward humans

Few researchers have studied the predictive ability of childhood animal cruelty motives as they are associated with later recurrent violence toward humans. Based on a sample of 180 inmates at one medium- and one maximum-security prison in a Southern state, the present study examines the relationship among several retrospectively identified motives (fun, out of anger, hate for the animal, and imitation) for childhood animal cruelty and the later commission of violent crimes (murder, rape, assault, and robbery) against humans. Almost two thirds of the inmates reported engaging in childhood animal cruelty for fun, whereas almost one fourth reported being motivated either out of anger or imitation. Only one fifth of the respondents reported they had committed acts of animal cruelty because they hated the animal. Regression analyses revealed that recurrent animal cruelty was the only statistically significant variable in the model. Respondents who had committed recurrent childhood animal cruelty were more likely to have had committed recurrent adult violence toward humans. None of the motives for committing childhood animal cruelty had any effect on later violence against humans.     

Serial killers with military experience: applying learning theory to serial murder

Scholars have endeavored to study the motivation and causality behind serial murder by researching biological, psychological, and sociological variables. Some of these studies have provided support for the relationship between these variables and serial murder. However, the study of serial murder continues to be an exploratory rather than explanatory research topic. This article examines the possible link between serial killers and military service. Citing previous research using social learning theory for the study of murder, this article explores how potential serial killers learn to reinforce violence, aggression, and murder in military boot camps. As with other variables considered in serial killer research, military experience alone cannot account for all cases of serial murder. Future research should continue to examine this possible link.     

The social and emotional context of childhood and adolescent animal cruelty: is there a link to adult interpersonal crimes?

The link between early animal abuse and later violence toward humans may depend on how acts of animal cruelty are experienced by those whose behavior demonstrates this graduation. Unfortunately, the research investigating the social and emotional context for the youthful commission of animal cruelty as it escalates to adult interpersonal violence is relatively nonexistent. Using 112 cases from a larger sample of 261 inmates surveyed at both medium and maximum security prisons in a southern state, the present study examined the effects of age of onset and frequency of animal cruelty, the covertness of animal cruelty, the commission of animal cruelty within a group or in isolation, and empathy for the abused animals. Inmates who had covered up their childhood and adolescent animal cruelty were more likely to have been convicted of repeated acts of interpersonal violence, demonstrating that the role of empathy and individuals present during acts of animal cruelty were less important than concealing those acts.     

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.     

Exploring the social and emotional context of childhood animal cruelty and its potential link to adult human violence

ABSTRACT

Those who commit acts of animal cruelty may do so differently based upon how they individually experience such acts. These experiences may impact the link that exists between childhood animal abuse and later interpersonal violence. Limited research exists that examines how social and emotional factors such as being upset after committing animal cruelty may impact the progression from early acts of animal cruelty to later acts of adult violence against humans. Based on responses from 180 prison inmates in a Southern state, the current study examined the effects of onset and frequency of animal cruelty, covertness of animal cruelty, the commission of animal cruelty alone or in a group, and being upset after committing animal cruelty. Inmates who committed recurrent acts of childhood animal cruelty were more likely to commit recurrent acts of adult interpersonal violence.     

Paths to destruction: the lives and crimes of two serial killers

Although research into the phenomenon of serial murder has revealed that serial killers frequently do not fit the initially described paradigm in terms of their physical and psychological profiles, backgrounds, and motives to kill, the media continues to sensationalize the figures of such killers and the investigators who attempt to analyze them on the basis of aspects of their crimes. Although the so-called "typical" profile of the serial murderer has proven accurate in some instances, in many other cases the demographics and behaviors of these killers have deviated widely from the generalized assumptions. This report details two unusual cases in which five and eight murders were committed in upstate New York. The lives and crimes of these offenders illustrate the wide spectrum of variations in the backgrounds, demographics, motivations, and actions witnessed among serial murderers, and highlight the limitations and dangers of profiling based on generalities.     

Childhood and adolescent animal cruelty methods and their possible link to adult violent crimes

Few researchers have investigated the potentially predictive power of childhood and adolescent animal cruelty methods as they are associated with subsequent interpersonal violence in adulthood. Based on a sample of 261 inmates at medium- and maximum-security prisons in a southern state, the present study examines the relationship between several retrospectively reported animal cruelty methods (drowned, hit or kicked, shot, choked, burned, and had sex) and violent criminal acts committed against humans (assault, rape, and murder). More than half of the sample reported they had shot animals, and almost half had either kicked or hit them. About one in five said they had choked animals, and about one in seven said they had either drowned, burned, or had sex with them. Regression analyses revealed that drowning and having sex with an animal was predictive of later interpersonal violence as adults.     

The effect of inmates' self-reported childhood and adolescent animal cruelty: motivations on the number of convictions for adult violent interpersonal crimes

Few researchers have investigated the potentially predictive power of motives for childhood and adolescent animal cruelty as it is associated with interpersonal violence in adulthood. Based on a sample of 261 inmates at medium- and maximum-security prisons in a southern state, the present study examines the relationship among several retrospectively reported motives (anger, fun, dislike, and imitation) for animal cruelty and violent crime convictions (assault, rape, and murder). Almost half reported abusing animals out of anger, whereas more than one third did so for fun. Dislike for the animal and imitation were less frequently occurring motives. Participants who abused animals at an earlier age and those who did so out of anger or for fun were more likely to repeat the offense. Regression analyses revealed that abusing an animal out of fun in their youth was the most statistically salient motive for predicting later interpersonal violence as adults.     

Frequency of serial sexual homicide victimization in Virginia for a ten-year period

The frequency of serial sexual murder has been widely discussed, and estimates of the number of victims in the United States range from 500 to 6000 per year. This study attempted to quantify the number of serial sexual murder victims in Virginia for a ten-year period. Multiple sources of data were utilized, including Federal Bureau of Investigation (FBI) case files, FBI's Violent Criminal Apprehension Program (ViCAP) reports, Virginia State Police ViCAP reports, Virginia Homicide Investigators Association, and the Virginia Division of Forensic Science DNA database, to effectively cull out all the known serial sexual murder victims for the given time period. Review of these records revealed a total of 28 victims of serial sexual murder, compared with a total of 5183 murder victims for the same ten-year period. The frequency of serial sexual victimization was 0.5% of all homicides for the given period. These results highlight the unusual frequency of serial sexual murder.     

Exploring the potential of stricter gun restrictions for people with serious mental illness to reduce homicide in the United States

This study explores the potential that current efforts to limit access to firearms for individuals with serious mental illness (SMI) have for reducing overall rates of murder by firearm in the United States. Official arrest, court and health records provided data on personal and offense characteristics of 95 individuals with SMI and 423 without, all of whom had been convicted of murder in the State of Indiana between 1990 and 2002. Bivariate analyses examined differences between the two groups and logistic regression models examined the relationship between SMI and offense characteristics. Compared to those without, a relatively small proportion of convicted murderers had a diagnosis indicating SMI. The presence of SMI was associated with reduced likelihood of targeting a stranger and was not associated with having multiple-victims or firearm use. Focusing on access to firearms exclusively by individuals with SMI will have little impact on multiple-victim or firearm-related homicides.     

Is animal cruelty a "red flag" for family violence? Investigating co-occurring violence toward children, partners, and pets

Cross-reporting legislation, which permits child and animal welfare investigators to refer families with substantiated child maltreatment or animal cruelty for investigation by parallel agencies, has recently been adopted in several U.S. jurisdictions. The current study sheds light on the underlying assumption of these policies-that animal cruelty and family violence commonly co-occur. Exposure to family violence and animal cruelty is retrospectively assessed using a sample of 860 college students. Results suggest that animal abuse may be a red flag indicative of family violence in the home. Specifically, about 60% of participants who have witnessed or perpetrated animal cruelty as a child also report experiences with child maltreatment or domestic violence. Differential patterns of association were revealed between childhood victimization experiences and the type of animal cruelty exposure reported. This study extends current knowledge of the links between animal- and human-directed violence and provides initial support for the premise of cross-reporting legislation.     

Exploring the age of onset and recurrence of childhood animal cruelty: can animal cruelty be learned from witnessing others commit it?

Despite recent research, few studies have examined the specific social contexts in which animal cruelty may be learned. Using data collected from 180 inmates at a medium- and maximum-security prison in a southern state, the authors seek to replicate findings from the Hensley and Tallichet study that examined the potential for the onset and recurrence of childhood animal cruelty to become a learned behavior, specifically in terms of demographic characteristics and childhood experiences with witnessing animal abuse. In the current study, those who were younger when they first witnessed animal cruelty initially hurt or killed animals themselves at a younger age. Respondents who had witnessed a family member hurt or kill animals reported engaging in recurrent animal cruelty and were older when they committed their first act of animal cruelty.

The predictive value of childhood animal cruelty methods on later adult violence: examining demographic and situational correlates

The present study seeks to replicate Tallichet, Hensley, and Singer's research on childhood animal cruelty methods by using a sample of 180 male inmates surveyed at both medium- and maximum-security prisons in a southern state. The purpose of the current study was to first reexamine the relationship between demographic and situational factors and specific methods of childhood animal cruelty. Second, the correlation between an abuser's chosen method(s) of childhood animal cruelty on later recurrent acts of adult violent crimes was reinvestigated. Regression analyses revealed that respondents who engaged in frequent animal cruelty were more likely to have drowned, shot, kicked, or had sex with animals. Those who had grown up in urban areas and those who did not become upset after abusing animals were more likely to have kicked animals. Respondents who covered up their abuse were more likely to have had sex with animals. Sex with animals was the only method of childhood animal cruelty that predicted the later commission of adult violent crimes.     

Mephitic projects: a forensic leisure science analysis of the BTK serial murders

Although it has been suggested among both forensic experts and a small number of leisure scientists that serial murder may be a form of recreational leisure, such suggestions remain largely unexplored both theoretically and empirically. Given the absence of scholarship on this possibility, this project explored and analyzed the structure and function of leisure activities within an unusual case (Dennis Rader) of serial murder. A thorough analysis of relevant case documents confirmed that serial murder itself can be experienced by the killer as a form of recreational leisure with the potential for optimal psychological experience (flow), and that various leisure activities may function in specific ways within the serial murder process. An unexpected finding in this case was that leisure, specifically project-based leisure, served to structure specific killings. Findings provide valuable new insights for forensics behavioral experts that may be used to guide future research.     

Sequential angulation,spatial dispersion and consistency of distance attack patterns from home in serial murder,rape and burglary

Abstract

Three related measures of spatial movement (sequential angulation, spatial dispersion and consistency of distance in attack target) were compared across three serial offence types: serial homicide (n=35), serial rape (n=41) and serial burglary (n=30). In each case, each offender had committed at least five offences. “Spatial dispersion”, defined as the extent to which an offender distributes his offences across either a focused or relatively more evenly distributed area, revealed that burglary was less evenly distributed (i.e. more focused) than rape and murder. “Sequential angulation”, defined as the degree of rotational movement around the home of the offender from one offence to the next, revealed that serial murderers have higher angulation scores than do rapists who, in turn, have higher angulation scores than burglars. Lastly, a comparison of the offender's consistency in the relative distance travelled from home to each attack site (“consistency of distance in attack target”) was relatively similar across the three groups. This was despite the comparison of different serial offence types from disparate geographical areas. The supposition that differences in dispersion and sequential angulation scores across crime types are related to the perceived risk of the crime has been confirmed. The specificity and the mobility of the targets are also discussed.     

A methodological model

Clues derived from the locations connected to violent repeat criminal offenders, such as serial murderers, rapists, and arsonists, can be of significant assistance to law enforcement. Such information allows police departments to focus their activities, geographically prioritize suspects, and to concentrate saturation or directed patrolling efforts in those zones where the criminal predator is most likely to be active. By examining spatial data connected to a series of crime sites, this methodological model generates a choropleth probability map that indicates the areas most likely to be associated to the offender—home, work site, or travel routes. Based on the Brantingham theoretical structure and the routine activities approach, the model goes beyond simple cluster or centroid analysis by employing specific serial murder research, overlapping modified Pareto functions, and Manhattan distances. The methodology is also sensitive to the target/victim opportunity backcloth, landscape issues, and problems of spatial “outliers.”
