The relationship between the quantity of alcohol consumed and the severity of sexual assaults committed by college men

Researchers have suggested that intoxicated perpetrators may act more violently than other perpetrators, although empirical findings have been mixed. Past research has focused on whether or not alcohol was consumed, rather than the quantity consumed, and this may explain these inconsistent findings. The authors hypothesized that the quantity of alcohol consumed would have a curvilinear relationship to the severity of the assault. Data were collected from 113 college men who reported that they had committed a sexual assault since the age of 14. The quantity of alcohol that perpetrators consumed during the assault was linearly related to how much aggression they used and was curvilinearly related to the type of sexual assault committed. The quantity of alcohol that victims consumed during the assault was linearly related to the type of sexual assault committed. Strategies for improving assessment of alcohol consumption in sexual assault research are discussed.     

Multiple perpetrator sexual assault: how does it differ from assault by a single perpetrator?

Research that attempts to identify characteristic features of multiple perpetrator sexual assault (MPSA) is limited. This study compared demographic and assault related characteristics of 135 cases of MPSA with 139 cases of single perpetrator sexual assault (SPSA) reported to the Haven sexual assault referral centre, Camberwell, London, over a 4-year period, and aimed to identify any unique features of MPSA victims, perpetrators and assault type. Victims of MPSA were younger, less likely to be White, more likely to report previous self-harm and more likely to sustain injuries than victims of SPSA. Multiple perpetrators were younger, less likely to be White and more likely to be strangers to the victim than single perpetrators. The nature of the assault was different in single and multiple perpetrator cases; in MPSA, there were more completed rapes and more multiple rapes, and perpetrators were more likely to meet the victim in an outside location before carrying out the assault in a place of residence that was not the victim's. These findings add to a scant but growing evidence base.     

Circumstances surrounding male sexual assault and rape: findings from the National Violence Against Women Survey

Much work in the area of male sexual assault and rape relies on small clinical samples. From these samples, researchers reported that most male victims were physically injured during the attack and that penetration occurred. This work rests on a subsample of 219 men from the 1994-1996 Violence and Threats of Violence Against Women and Men in the United States Survey. Findings from the National Violence Against Women Survey (NVAW) show that the vast majority of male sexual assault victims reported that they were not physically injured during the assault, that a weapon was not used, that there was no substance use at the time of the assault, and that penetration did not occur. Only 29% of male respondents in the NVAW sought medical or psychological help after the assault. Prior work may have overrepresented men who reported being physically injured and/or penetrated. An analysis is presented of how those who presented for help in the NVAW differ from the whole sample. Results show that men who presented for help were more likely to have reported being physically injured during the assault and that penetration occurred. Thus, findings from prior work make sense; however, they may not be representative of male assault victims as a whole.     

Perpetrators of sexual assault continuing to have sex with their victims following the initial assault: evidence for evolved reproductive strategies

Among a sample of college students, roughly 30% of the women and 12% of the men reported having been the victim of a sexual assault sometime in their lives. Of the assault victims, approximately 23% of both sexes stated that they had sexual intercourse with their assaulters on at least one subsequent occasion. Female victims of a completed sexual assault were significantly more likely to continue being sexually active with their assailants than were female victims who managed to block the assault, while no such difference was found for male victims. This would imply that some men are using assaultive tactics to secure sex partners beyond a single sexual episode, thereby enhancing their potential reproductive success in evolutionary terms. Also, men who committed sexual assault reported having had more lifetime sex partners than did sexually experienced men with no sexual assault history. Overall, the idea that sexual assault is part of an evolved reproductive strategy is consistent with findings from this study.     

Patterns in sharp force fatalities--a comprehensive forensic medical study

A ten-year series of 142 homicidal fatalities caused by sharp force injury was studied with the aim to systematize information inherent in the characteristics of the victim and the pattern of injuries. The population of victims consisted of 112 males (79%) and 30 females (21%); among perpetrators, 125 (88%) were males. Among victims as well as among perpetrators, persons of non-Swedish origin were overrepresented in relation to their share of the nonselected population. In 82 cases (58%), one or two wounds had been inflicted; in 23 cases (16%), ten or more wounds. In the latter group, eleven victims but no perpetrators were female. In the majority of cases victim and perpetrator were known to each other, and in instances of multiple wounding, a close relationship between the two was clearly more common than in the group of one- to two-wound fatalities. Tests for blood alcohol were positive in 86 of 116 victims (74%), the majority being in elimination phase. Furthermore, 96 of 120 perpetrators (80%) had positive tests or were known to be drunk at the time of the killing. In multiple wound fatalities, alcohol inebriation was less common both among victims and perpetrators. In these cases, the two persons involved were usually closely related or intimately known to each other, and in the absence of psychiatric disorder in the assailant, the motive was of a passionate type.     

Screening analysis for medicinal drugs and drugs of abuse in whole blood using ultra-performance liquid chromatography time-of-flight mass spectrometry (UPLC-TOF-MS)-Toxicological findings in cases of alleged sexual assault

An ultra-performance liquid chromatography time-of-flight mass spectrometry (UPLC-TOF-MS) method for simultaneous screening of 46 medicinal drugs and drugs of abuse in whole blood was developed and validated. The method includes most of the commonly used and abused drugs such as amphetamines, cocaine, benzodiazepines, and opioids. Chromatographic separation of the targeted drugs was achieved using a Waters ACQUITY UPLC coupled to a Waters Micromass LCT Premier XE time-of-flight mass spectrometer. The total chromatographic run time was 13.5min injection to injection. The estimated method LOQ is in the range of 0.06-27ng/g, which is below the therapeutic levels for each of the drugs analyzed but LSD. The extraction recovery ranged from 6% to 197% with median value 95% and mean value 82%. Matrix effect ranged from 81% suppression to 29% enhancement of the signals compared to signals obtained in the absence of biological matrix. The method was tested on 55 authentic forensic toxicology samples confirming the same positive results as found using the routine analytical procedures as well as some additional compounds. Recently there has been considerable attention paid to drug-facilitated sexual assault and the toxicological findings in these cases. As part of a pilot study to investigate the prevalence of medicinal drugs, drugs of abuse, and alcohol in victims of alleged sexual assault, biological specimens were obtained from 167 victims being examined at the Sexual Assault Center in Aarhus, Denmark. The obtained blood samples were analyzed using the novel screening method supported by additional analyses for e.g. THC and alcohol. 124 victims reported they have been drinking alcohol prior to the assault (74%). Alcohol analyses revealed 59 positive findings (48%). 35 of the cases were found positive for one or more drugs excluding alcohol (21%). 20 of the victims reported they have been subject to a drug-facilitated sexual assault (12%). For the victims suspecting drug-facilitated sexual assault, the toxicological analyses revealed four positive for alcohol and nine victims were positive for one or more drugs, with six of the victims found positive for benzodiazepines or other drugs with sedative effects. It was notable that victims tested positive for medicinal drugs and drugs of abuse as well as victims of alleged drug-facilitated sexual assault in average underwent medical examination later than the whole study population.     

Interpersonal violence cases reported to the police: a Nigerian study

The study involves 204 cases of interpersonal assault reported to the police during a period of 1 year. The patterns of domestic violence and community violence involving friends, neighbors, and strangers are described. The most common type of violence reported to the police is community interpersonal violence in which victims are mostly females and perpetrators are mostly males and members of gangs. Cases of rape are reported, whereas spousal violence tends to be underreported. On the whole, female victims are more likely to be younger than their male counterparts, whereas the male perpetrators are more likely to be unemployed. Repeat assault is found in 43 instances. Possible psychological and sociological explanations are offered for violent gang activities. The need to sensitize the police to become more involved is emphasized. The author proposes suggestions that may help reduce the incidence of community violence.     

Lessons learned and unanswered questions about sexual assault perpetration

The most important lesson learned about interpersonal violence in the past 20 years is the astonishingly high prevalence of sexual assault in American society. The extensiveness of unreported sexual assault has been repeatedly documented through the use of self-report data from well-constructed surveys of victims and perpetrators. In contrast, little has been learned about how to effectively reduce rates of sexual assault perpetration. Theoretically derived universal prevention programs targeted at adolescents are sorely needed.     

The spectrum of sexual abuse in daycare: An exploratory study

Findings from an exploratory study of 48 children sexually abused in daycare centers and daycare homes are presented. About two thirds were female and one third male. Approximately half of victims were maltreated by a single perpetrator and about half by more than one perpetrator, in the latter instance almost always by both men and women. On average, the children were subjected to 5.3 types of sexual abuse, experienced 2.1 different sorts of threats to obtain their cooperation or prevent disclosure of their victimization, and suffered from 3.7 symptoms regarded as sequelae of sexual abuse. Differences in the characteristics of offenders, victims, the sexual abuse, threats, and sequelae were found based upon the daycare context, that is, whether children were victimized in a center with multiple perpetrators, a center with a single perpetrator, or a daycare home.     

Locard's Principle of Exchange,Dental Examination and Fragments of Skin

The transfer of materials between victim and perpetrator was first reported by Locard in the nineteenth century. While in recent years DNA testing has been very successful in matching biological material from crime scenes to perpetrators, the following cases demonstrate that other more time‐honored methods remain useful. Two cases of lethal assault are reported where the victims had bitten their assailants resulting in fragments of the perpetrators’ skin being wedged between their teeth which were discovered during post mortem oral examinations. As the fragments were able to be matched to injuries in the perpetrators, identification was established prior to confirmatory DNA testing. In case 1 a criminal conviction for manslaughter resulted, and in case 2 the identity of the assailant was confirmed. Examination of a properly exposed and illuminated oral cavity may provide useful evidence in assault cases. These cases represent an unusual dental variant of Locard's principle.     

Temporary Restraining Orders in the Netherlands: A Qualitative Examination of Perpetrator and Victim Views

In 2009, the Netherlands introduced a 10-day temporary restraining order (TRO) intended for adult perpetrators of domestic violence to defuse dangerous situations and to reduce recidivism by combining a legal action with social services. For this study, 18 victims and 10 perpetrators were interviewed about their experiences with the TRO, related professional help, and the influence the TRO had had on their lives. The interviews were transcribed verbatim and subsequently qualitatively analyzed. Most of the victims were positive about the TRO period. Perpetrators were less positive. The vast majority of respondents accepted help during the TRO and were positive about the professionals’ attitudes, but not necessarily about the type of help. Most respondents reported an increase in their wellbeing, new insights, and no or less serious re-assaults by the perpetrator. The results suggest that, in the short term, TROs have a mainly positive effect on both victims and perpetrators.     

The link between recurrent maltreatment and offending behaviour

This article considers recurrent maltreatment and offending behaviour. The sample was 60 males and 19 females (11 to 18 years) resident within a secure institution in England and considered a risk to themselves and/or others. Overall, 20.8% had not experienced maltreatment, 6.5% had experienced a single incident, 11.7% were repeat victims (same perpetrator), 6.5% were revictimised (different perpetrators), and more than half (54.5%) had suffered both repeat and revictimisation. Of those who had committed a violent and/or sexual crime, 74% had experienced some form of revictimisation, compared to 33% of those who committed nonviolent offences. Those young people most likely to have committed violent and/or sexual crimes were those who had been victims of recurrent extrafamilial maltreatment (many of whom had also experienced recurrent intrafamilial maltreatment). Thus, in this sample, revictimisation was associated with serious crimes. However, these findings are preliminary, and prospective research with a larger sample is needed.     

Analysis of 1989-1999 homicide crimes in the catchment area of the Bonn Institute of Forensic Medicine with reference to selected aspects

195 cases of homicide, grouped according to juridical assessment, were retrospectively analysed with regard to individual characteristics of perpetrators and victims, circumstances, and mode of commitment. The involvement of underage victims and perpetrators as well as differences between the urban and rural areas studied were taken into special consideration. To summarise, the majority of the offences studied was carried out by a male perpetrator with a mean age of 35 years driven by personal motives or greed in his immediate vicinity and affected family members or close acquaintances. The fatal injuries were mainly attributable to sharp or blunt force. With regard to killings of children, a higher prevalence of female victims and male assailants, emotional motives and an even higher importance of the social vicinity were found. Particularly in victims younger 12 years of age, manual modes of commitment without application of any tools were predominantly encountered. The comparison of urban and rural areas revealed a higher homicide rate in municipal areas especially of offences with a loose relationship between victims and assailants (greed, sexual assault). In contrast, rural areas exhibited higher rates of bodily harm with fatal consequences as well as offences by highly intoxicated assailants.     

Do trials of perpetrators retraumatize crime victims?

Attendance at trials of perpetrators could be retraumatizing for crime victims suffering from posttraumatic stress disorder. To investigate this hypothesis, two studies were conducted in which retraumatization was defined as a significant increase in posttraumatic stress reactions. A cross-sectional study of 137 victims of rape and nonsexual assault revealed that trial variables do virtually not predict posttraumatic stress reactionsat a time several years after trial. A longitudinal study of 31 victims of rape and nonsexual assault revealed intraindividual stability of posttraumatic stress reactions for the time interval from a few weeks before the trial to a few weeks after the trial; in addition, interindividual stability was high. The results of both studies do not support the retraumatization hypothesis, which should therefore be used with caution.     

Stranger and acquaintance sexual assault of adult males

This study examined victim and assault characteristics and the nature and extent of coercion, violence, and physical injuries among adult male victims of sexual assaults. Client records of three groups presenting to a sexual assault care center were included: males assaulted by a stranger (n = 64), males assaulted by an acquaintance (n = 81), and females assaulted by an acquaintance (n = 106). Study results revealed that male victims of sexual assault tended to be young, single men who reported high rates of vulnerabilities such as homelessness and physical, psychiatric, and cognitive disabilities. Male stranger assailant victims were more likely to experience assaults involving weapons and physical violence. Injuries sustained by victims and services delivered at the sexual assault care center were similar for both male and female clients. The results of this study reveal new information about violence in male sexual assaults and the vulnerability of the male victims.     

Factors Influencing the Filing of Complaints,Their Investigation,and Subsequent Legal Judgment in Cases of Sexual Assault

In Geneva, examination of victims of sexual assault is performed by a gynecologist and a medical examiner. 48% of the victims file a complaint and we wanted to investigate the factors leading to file a complaint, those leading the Prosecutor to go to trial, and those influencing a conviction. Between 2006 and 2012, 676 victims of sexual assault were investigated (averaged age 26 year, mean 22). Information on injuries, perpetrators, and circumstances of the assault was collected and analyzed. The attacker being the ex‐spouse or a friend and the presence of semen were factors leading to file a complaint. The assailant being a family member or ex‐spouse and the presence of genital/anal lesions were factors influencing the Prosecutor. The presence of nongenital lesions, the assailant being known by the victim, influenced conviction. This study shows that the medical examiner plays a vital role in the investigation of cases of sexual assault.     

Sexual assaults in Geneva between 2006 and 2010

In Geneva, all sexual assault victims are examined both by a gynaecologist and a forensic pathologist with special training in clinical forensic medicine. Between 2006 and 2010, 473 victims were examined following such an assault. Over the years, the number of sexual assaults rose steadily. Most victims were aged between 15 and 30 years. The majority of the assaults occurred at night and on the weekend and often happened at the place where the perpetrator or the victim lived. Usually, the offender acted alone and was known to the victim. Many victims hesitate to present for an examination, which makes it difficult to collect evidence. Penetration was usually vaginal and without the use of a condom. Injuries on the body or genitals were seen in only half of the cases for the first ones and in less than one third for the second ones. Quite often (at least in 42 % of the cases), the victim consumed alcohol before the assault and the use of drugs--especially cannabis--was not uncommon either.     

Homicide‐Suicide in Konya,Turkey Between 2000 and 2007*

Abstract: Homicide followed by the suicide of the murderer is a relatively rare lethal incident in which an individual kills another person and subsequently dies by suicide. Cases involving a homicide and a suicide in which death examinations and autopsies were performed at The Konya Branch of the Forensic Medicine Council between 2000 and 2007 were retrospectively investigated. During the studied time period, there were 10 homicide‐suicide cases identified with 10 perpetrators killing 12 victims. Nine of the perpetrators were men and eight of the victims were women. The precipitating motive was an impending divorce in four of the cases. Two perpetrators were described as severely depressed, one had a diagnosis of antisocial personality disorder, and one was a pedophile who had reactive depression. Firearms were used in eight of the homicide cases and seven of the suicides. Constricting the use of firearms may reduce/prevent future homicide‐suicide cases, as it is the most commonly used method to carry out homicide‐suicides.     

Divergent Perspectives: Exploring a Multiple Informant Approach to Cyberbullying Victimization and Perpetration

The present research adopts a multiple informant approach to identify victims and perpetrators of cyberbullying. Similar approaches have been successfully applied in the field of traditional bullying, and they are highly relevant for studying cyberbullying as well. Three informants can provide key perspectives on cyberbullying incidents: victims, perpetrators, and bystanders. To collect data on these actors, all eighth-grade students in 11 secondary schools were invited to participate in a survey. In total 1458 respondents completed peer-nomination questions on cyberbullying involvement. The results indicated that the prevalence of cyberbullying varied depending on the type of informants that was consulted. In addition, limited overlap was observed between the reports of different informants, resulting in different profiles of victims and perpetrators, depending on the informants that identified them. In sum, different informants tended to have divergent views on cyberbullying, which has important implications. It warrants accurate reporting and critical reflection on the sources of data in cyberbullying research. Moreover, it demonstrates the need to study a more diverse set of informants to advance the understanding of cyberbullying and to enhance prevention efforts.
