Recent studies have offered compelling evidence supporting a relationship between childhood cruelty to animals and later violence against humans. This study investigated whether violent offenders were significantly more likely than nonviolent offenders to have abused animals of various types during childhood. Interviews were conducted with 45 violent and 45 nonviolent offenders incarcerated in a maximum-security prison and randomly selected for this study by institutional staff members. Two data collection instruments were used. The first extracted demographic and social history from the participants. The second was used to gather information regarding cruelty to animals as categorized into four types (wild, farm, pet, and stray). Results indicated that a statistically significant relationship existed between childhood cruelty to animals and later violence against humans. Furthermore, the study found, consistent with prior research, that violent offenders were significantly more likely than nonviolent offenders to have committed acts of cruelty toward pet animals as children.
The reliability and predictive validity of two experimental self-report versions of two measures of psychopathic features in youth, the Antisocial Process Screening Device (APSD: Frick & Hare, 2001) and a modified version of the Child Psychopathy Scale (CPS: Lynam, 1997) were examined in a sample of 69 arrested youth (M age = 14.4 years) referred to a juvenile diversion program. Parents or legal guardians completed parent-rating versions of the same measures. Reliability indicators for the APSD total measure were satisfactory although internal consistency indices (coefficient alpha) for the Callous/Unemotional and Impulsive/Conduct Problems scales were slightly lower than desirable. Reliability indicators for the CPS were excellent after deleting items that had poor corrected item-to-CPS total score correlations. Positive and statistically significant correlations for all measures were obtained with prospective measures of program failure (range 0.22-0.36) and rearrest at 1 year follow-up (range 0.33-0.56). Although further research is needed prior to the clinical use of these measures, these results signal the potential of such measures to inform clinical judgments regarding treatment compliance and risk with justice-involved youth.
This article first synthesizes the literature on clinical and empirical findings related to youth homicide. Thereafter, it reviews the literature with respect to the treatment of juvenile homicide offenders. Although a large body of literature exists, many questions regarding etiology, associated risk factors, intervention strategies, and long-term outcomes remain unanswered. The article concludes with recommendations to guide future research efforts with the aim of increasing understanding of etiological factors associated with juvenile homicide and designing effective intervention strategies. Greater advances in knowledge will follow with the implementation of enhanced methodological designs that examine juvenile homicide across four distinct time frames: the years preceding the homicide, the time period immediately following the homicide, the incarcerative or treatment period, and the post-release period.
Most studies of sexual murderers consist of small samples made up of primarily adult offenders. Accordingly, little is known about similarities and differences between juvenile (under 18) and adult (over 18) sexual murderers. This article is the fi rst to utilise a large sample (n = 3845) that spans almost three decades of Supplemental Homicide Reports data to analyse juvenile (n = 452) and adult (n = 3393) sexual murderers, particularly in terms of weapons used to kill different victim types. This study underscores the importance of analyses of specifi c types of murderers. In comparison with homicide arrestees, those arrested for sexual murder were more likely to be male, less likely to be black, and about as likely to be under 18. Consistent with previous literature, sexual murderers in this study were more likely to use personal and close contact weapons than fi rearms and other more distant methods of killing. Several signifi cant differences emerged in weapons selected to kill different victim types between juvenile and adult offenders. Findings with respect to weapon selection by offender age groups are consistent with Heide's physical strength hypothesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
