Likelihood of Arrest for Robberies, Assaults, and Sexual Offenses Committed by Group and Lone Offenders.

Many criminologists have considered the role of groups in the commission of crime to gain insight into offender decision-making. Additional research is needed, however, that examines the likelihood of arrest as a function of whether an offense is committed by a group of offenders (two or more offenders in a criminal incident) or a lone offender, as well as the number of offenders in the group. Using 3 years of data from the National Incident-Based Reporting System for robbery incidents, assault incidents, and sexual offenses, the study finds that the relative likelihood of arrest for group-offender incidents, compared with lone-offender incidents, varies by incident type. For robbery incidents, the likelihood of arrest increases when committed by a group of offenders. Yet, for assault incidents and sexual offenses, the likelihood of arrest decreases when committed by a group of offenders. Further analysis looks more closely at incidents committed by a group of offenders and how the number of offenders in the group affects the likelihood of arrest. A consistent finding is that for each incident type, the likelihood that all offenders in a group will be arrested is lower as the number of offenders increases, which may justify offenders' perceptions of "safety in larger numbers."

Solo and Multi-Offenders Who Commit Stranger Kidnapping: An Assessment of Factors That Correlate With Violent Events.

Research has demonstrated that co-offending dyads and groups often use more violence than individual offenders. Despite the attention given to co-offending by the research community, kidnapping remains understudied. Stranger kidnappings are more likely than non-stranger kidnappings to involve the use of a weapon. Public fear of stranger kidnapping warrants further examination of this specific crime, including differences between those committed by solo and multi-offender groups. The current study uses National Incident-Based Reporting System (NIBRS) data to assess differences in use of violence among 4,912 stranger kidnappings by solo offenders and multi-offender groups using cross-tabulations, ordinal regression, and logistic regression. The results indicate that violent factors are significantly more common in multi-offender incidents, and that multi-offender groups have fewer arrests than solo offenders. The implications of these findings are discussed.

Juror Decision-making in Death Penalty Sentencing when Presented with Defendant's History of Child Abuse or Neglect.

Previous studies have found aggravating, mitigating, and null effects of defendant histories of abuse and neglect on punishment preferences in capital sentencing. Perceiving these defendants as more dangerous, jurors may be more likely to favor the death penalty when such evidence is presented. This is counter to the intuition that abuse or neglect reduces culpability, and therefore mitigates the severity of punishment. We investigated the effect of defendant childhood physical abuse, sexual abuse, or neglect on the probability of a prospective juror preferring the death penalty in an between-subject experimental design. Using vignettes and two large samples (students and jurors), defendant histories were found to mitigate the probability that the hypothetical defendant received the death penalty, with sexual abuse having the most salient effect. Further, the effects were conditioned by preference for the death penalty - larger mitigating effects were observed among individuals who favor the death penalty. These findings suggest that initial judgments of abuse and neglect are related to juror leniency, and further research on the interaction of jury instructions and defendant histories is needed.

Factors that affect college students' perceptions of rape: what is the role of gender and other situational factors?

Prior research has shown that various situational factors and behaviors can affect one's perception of whether a rape has occurred. Moreover, some hold false beliefs about rape. This can also affect one's perception of ambiguous situations. This study included the administration of a survey to 584 college students; the survey examined the prevalence of rape myths and responses to vignettes of potential rape scenarios. It was found that although the majority of this sample did not support rape myths, male students were significantly more likely than female students to support rape myths. Furthermore, approximately 20% of students did support one subscale of the rape myth scale: He didn't mean to [commit rape]. The results also revealed an interaction effect between the observer's sex and the victim's sex, suggesting a complex gender relationship.

Assessing gender differences and co-offending patterns of a predominantly "male-oriented" crime: a comparison of a cross-national sample of juvenile boys and girls arrested for a sexual offense.

This study examines male-female differences of juveniles arrested for a sex offense. A cross-national sample of juvenile boys (n = 177) and a population of juvenile girls (n = 177) arrested for a sex offense are utilized for this analysis. It is hypothesized that (1) boys and girls differ substantially in their offending patterns. Based on Moffitt's social-amplification hypothesis, it is also hypothesized that (2) juveniles who act with a co-offender commit more serious offenses (i.e., more likely to be arrested for rape and have more victims) compared to those who act alone. The results show boys differ from girls: juvenile girls are slightly younger, more likely to be White, more likely to have a co-offender, less likely to commit rape, and be processed formally by law enforcement. The results yielded indicated social amplification appears to occur when girls offend with a co-offender, but not when boys acted with a co-offender.

Assaultive behavior in bars: a gendered comparison.

This research assesses the prevalence, nature, and arrest patterns of barroom aggression; it includes a cross-national sample of men and women involved in simple or aggravated assault. Prior research indicates bars are a haven for assaults; however, little research has focused on female involvement in barroom assault. Data from the National Incident-Based Reporting System are used to assess differences between men (n=9262) and women (n=2787) involved in barroom assaults during 2005. Results shed light on an understudied population of barroom offenders. Specifically, women are younger than their male counterparts and more likely to use a weapon during a barroom altercation. Additionally, while barroom assault is intrasexual in nature, women are more likely than men to assault outside their sex.

Female sex offenders: a comparison of solo offenders and co-offenders.

Even though much of the prior sex offender literature focuses on males, recent research has included females as offenders. Such research, however, has been limited by small sample sizes. Several researchers have proposed typologies of female sex offenders that include both females who act alone (i.e., solo offenders) and females who act with another person (i.e., co-offenders), often a male. The current research includes a cross-national sample of 123 females who were solo offenders and 104 who were co-offenders. It was found that the two groups of females were not significantly different in regard to their age, race, time of offense, and the location of the offense. Co-offenders were more likely than solo offenders to have more than one victim, to have both male and female victims, to be related to the victim, and to have a nonsexual offense in addition to the sexual offense listed.

A prospective analysis of juvenile male sex offenders: characteristics and recidivism rates as adults.

This research assesses the recidivism rates of a sample of 300 registered male sex offenders who were juveniles at the time of their initial arrest for a sex offense. This sample is followed for 3 to 6 years after they reached adulthood; recidivism rates are assessed during their adulthood only. The typical juvenile is a 15-year-old Caucasian male who was arrested for sexual assault or indecency with a child. The majority of the victims are females with an average age of 8. Although only 13 are rearrested during the follow-up period for a sex offense, more than half of the sample is arrested at least once for a nonsexual offense. The results of a Cox regression indicate that victim age, offender age, and victim sex are significant predictors of recidivism during adulthood.

Juvenile female and male sex offenders: a comparison of offender, victim, and judicial processing characteristics.

This research examines 61 juvenile female sex offenders in terms of their offending patterns, demographics, and victim characteristics; these findings are compared to 122 juvenile male sex offenders. Relying on sex offender registration data and criminal history records, bivariate analyses are conducted to assess male-female differences. Logistic regression is also employed to further assess group membership (male and female). Females were typically younger than males at the time of their arrest for a sex offense. Female offenders also chose male and female victims proportionately, whereas males were more likely to choose female victims. Logistic regression analysis revealed two significant predictors of the offender's sex: victim's sex and length of sentence. This research, therefore, indicates different modalities of offense characteristics for males and females, which predicates different management strategies in terms of identification for these groups of offenders.

Offender and victim characteristics of registered female sexual offenders in Texas: a proposed typology of female sexual offenders.

Victim and offender characteristic of all registered adult female sexual offenders in Texas (N = 471) were examined. The most common offenses the females were arrested for were indecency with a child--sexual contact, sexual assault on a child, and aggravated sexual assault on a child. The majority (88%) of the females were Caucasian and the ages ranged from 18 to 77 (M = 32). The results of Hierarchical Loglinear Modeling yielded a complex relationship between offender and victim characteristics; thus, identification of preferred victims is mitigated by more than one variable. Additionally, the employment of cluster analysis yielded 6 types of female sexual offenders. The most common group includes 146 offenders, heterosexual nurturers. They were the least likely to have an arrest for a sexual assault. The victims were males who averaged 12 years of age. The other types of offenders included, noncriminal homosexual offenders, female sexual predators, young adult child exploiters, homosexual criminals, and aggressive homosexual offenders.
