A growing number of U.S. cities and states have large numbers of unsubmitted sexual assault kits (SAKs) in police property facilities. Prior research conducted in large urban cities has found that testing these kits yields a sizable number of DNA profiles that meet FBI eligibility for upload to the national criminal DNA database CODIS (Combined DNA Index System) and uploaded profiles return a substantial number of matches to existing criminal profiles in CODIS. It is unknown whether these findings are unique to large urban cities with high crime rates. The purpose of current study was to document forensic testing outcomes from a state census of previously unsubmitted SAKs, which included large urban–suburban centers, as well as smaller cities and rural counties. We inventoried all previously unsubmitted SAKs in Michigan (N = 3422 SAKs) and submitted all kits for forensic DNA testing. A total of n = 1239 SAKs had a DNA profile that met eligibility for upload into CODIS (36.2% unconditional, 56.5% conditional CODIS eligible rate) and n = 585 SAKs yielded a CODIS Hit (17.1% unconditional, 47.2% conditional CODIS hit rate). These rates are consistent with studies from urban areas suggesting approximately half of SAKs tested yield a CODIS profile and approximately half of those uploaded profiles yield a hit. We compared SAK forensic testing outcomes by geographic and population density characteristics, and although rates were often higher in larger metropolitan areas, the obtained rates in micropolitan and rural areas suggest testing is warranted in smaller jurisdictions as well.  相似文献

A growing number of U.S. cities have large numbers of untested sexual assault kits (SAKs) in police property facilities. Testing older kits and maintaining current case work will be challenging for forensic laboratories, creating a need for more efficient testing methods. Methods: We evaluated selective degradation methods for DNA extraction using actual case work from a sample of previously unsubmitted SAKs in Detroit, Michigan. We randomly assigned 350 kits to either standard or selective degradation testing methods and then compared DNA testing rates and CODIS entry rates between the two groups. Results and conclusions: Continuation‐ratio modeling showed no significant differences, indicating that the selective degradation method had no decrement in performance relative to customary methods. Follow‐up equivalence tests indicated that CODIS entry rates for the two methods could differ by more than ±5%. Selective degradation methods required less personnel time for testing and scientific review than standard testing.  相似文献

This study examined the impact of types of women's verbal refusals, and the timing of her refusal, on men's discrimination of when a female wants her partner to stop making sexual advances. Male students were randomly assigned to 1 of 6 conditions (Explanations × Intimacy Levels). Before listening to an audiotape of a date rape, participants were told they would be listening to an interaction between a man and a woman who had just returned from a date. They were instructed to indicate when the woman wanted the man to stop making sexual advances by pressing a switch that synchronously stopped a timer (yielding the measure of latency). In the vignette, the woman provided an explanation for not engaging in sexual intercourse on the date either during kissing or when the man attempted to touch her breasts. She offered one of three reasons for refusing his sexual advances; fear of pregnancy, waiting until marriage, too early in the relationship. Results revealed an interaction in which participants in the too early in the relationship explanation at the level of breast contact condition displayed significantly longer latencies than individuals in the other groups. The implications of the findings are discussed.  相似文献

In recent years, drugs including flunitrazepam, gamma-hydroxybutyrate, ketamine, and ethanol, have become popularly associated with drug-facilitated sexual assault. Other drugs are also candidates as factors in "drug facilitated sexual assault" (DFSA). The true extent of DFSA is not known, and is difficult to estimate. We recruited sexual assault complainants at four clinics in different parts of the U.S. to anonymously provide urine and hair specimens, and to answer questions about suspected drugging, drug use, and the sexual assault incident. Urine and hair specimens were tested for 45 drugs, including ethanol, and those pharmacologically capable of inducing sedation, amnesia, or impairment of judgment. Analytical test results were used to estimate the proportion of subjects, and the proportion of all complainants to the clinic in the same time period, who were victims of DFSA. Overall, cases of 43% of 144 subjects, and 7% of 859 complainants, were characterized as DFSA. Subjects underreported their use of drugs. The role of toxicological results and history in characterizing DFSA cases is discussed.  相似文献

Many protocols for the examination of sexual assault victims include the preparation of vaginal wet mount slides to determine whether sperm are present and if so, whether the sperm are motile. We have reviewed findings in 501 case reports to compare the efficiency of sperm detection on wet mounts to subsequent crime laboratory results of sperm searches on vaginal swabs. Sperm were detected on wet mounts in only 41% of cases in which sperm were detected in the crime laboratory. Motile sperm were observed in only 12% of cases reporting a 0–9 h postcoital interval; in three cases, motile sperm were seen at 15 h and beyond, indicating that motile sperm are not reliable evidence of a short postcoital interval. These findings demonstrate that wet mount examinations are of little value in guiding subsequent analyses in the crime laboratory or in corroborating other investigative aspects of the case.  相似文献

Abstract

The present study sought to identify consistent patterns in the actions of sexually violent offenders to determine whether sexual homicide and rape reflect different behavioral emphasis of a single thematic model of sexual assault. Crime scene behaviors of 74 (37 sexual homicides and 37 rapes) solved cases of sexual assaults were compared, and results of a multi-dimensional analysis revealed three thematic styles of interacting with the victim during a sexual assault (Exploit, Control, and Violent). Further analysis indicated that offender–victim interactions in sexual homicide and rape are predominantly distinguished by the degree of violence, such that behaviors associated with each type of offense were found to occur in two discrete areas along a single continuum. Findings are discussed in terms of producing a general framework for understanding sexual violent interactions.  相似文献

The frequent absence of a documented history of sexual assault/rape in the prior research on serial sexual murderers is curious. In order to address several methodological problems in prior research, a closed-case archival review of a nonrandom national sample of 53 serial sexual homicide cases was conducted which identified 14 offenders with a history of sexual assault/rape for an overall prevalence rate of 26.4%. Of the 14 offenders with a prior known history of sexual assault/rape, 11 (78.6%) sexually penetrated at least one of their homicide victims at the crime scene. Implications for investigation of serial sexual homicide as well as for further understanding of this exceptionally rare crime are presented.  相似文献

Violence against women is a problem around the world. Addressing the issues of physical and sexual violence against women has been a complicated endeavor for criminologists. Much of the traditional criminological research on violence against women has frequently focused on rape as a crime of power between individuals. However, this framework has been expanded to incorporate the analysis of rape during times of war and rape as a state crime. In these cases, rape serves a broader purpose within the military and social structure. By focusing on the specific case of the gang rape of Mukhtar Mai, the goal of this paper was to demonstrate and analyze the role of the state in many of these crimes. Mukhtar Mai’s case should not be understood in isolation, but as a way to illuminate the role of the state in these numerous crimes.  相似文献

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.  相似文献

Abstract:  We report on a case of extreme sexual self-mutilation in which the subject inflicted severe trauma to his genitalia and then falsely reported a sexual assault. The 30-year-old white male did not report the incident for 10 days and then checked into a hospital. The hospital called the Westminster Police Department after the subject reported that he was the victim of a sexual assault in our city. This case is unusual in that the subject's initial behavior and story did not indicate deception. It was not until the subject's computer was searched that investigators determined that the injuries were self-inflicted. Without this critical information the case might still remain open as a sexual assault. This case is reported to broaden our understanding of this behavior and inform investigators of the potential for this type of self-inflicted injury.  相似文献

This paper examines violent sexual assaults and the factors associated with those assaults with lethal outcomes. It utilizes a criminal events perspective in conceptualizing the nature of these assaults and divides the event into three domains: victim characteristics, situational characteristics, and crime characteristics. Using a method developed by Miethe, Hart, and Regoeczi, conjunctive analysis of case configurations, we find that certain characteristics of the crime itself and certain characteristics of the victim appear strongly associated with fatal outcomes in sexual assaults, while situational characteristics appear relatively weakly associated with lethality.  相似文献

Abstract: Little is known about the racial patterns of crimes committed by sexual homicide offenders (SHOs). This study examined race and age influences on victim–offender relationship for juvenile and adult SHOs. A large sample (N = 3868) from the Supplemental Homicide Reports (1976–2005) was used. Analyses of victim–offender patterns included examining victim age effects (child, adolescent, adult, and elderly). The findings revealed several race‐ and age‐based differences. Black offenders were significantly overrepresented in the SHO population. This finding held for juveniles and adults independently. White SHOs were highly likely to kill within their race, “intra‐racially” (range 91–100%) across four victim age categories, whereas Black SHOs killed both intra‐racially (range 24–82%) and inter‐racially (18–76%), with the likelihood of their killing inter‐racially increasing as the age of the victim increased. This study underscores the importance of considering victim–offender racial patterns in sexual murder investigations, and it offers practical implications for offender profiling.  相似文献

After a drug-facilitated sexual assault (DFSA), a woman was found in a drowsy state at home. She remembered having drunk an unknown beverage by the accused. Blood samples (collected 8 hours after the DFSA), two glasses, and a teaspoon seized by the police were analyzed. Acepromazine, a phenothiazine tranquilizer used in human and veterinary medicine, was detected in the residue of one of the glasses. In spite of acepromazine absence in the victim's blood, the possible use of acepromazine in the DFSA was reported to the police. Two weeks later, a suspect admitted having orally administered acepromazine to the victim. Using a liquid chromatography-tandem mass spectrometry method, this compound was subsequently detected (31 pg/mg) in a sample of the victim's hair collected a month and a half after the DFSA. A potential short elimination half-life in humans and/or the well-known in vitro degradation of acepromazine could explain the negative blood result. DFSA toxicological investigations are challenging and can be complicated when a rather unusual substance is concerned. In particular, special care should be taken when interpreting the results, taking into account elimination and/or instability data, when available.  相似文献

Implicit evaluations reflect people’s gut response toward an attitude object and are based on associative processes. They are the starting ground for more reflective processes and subsequent explicit evaluations. The present research examined determinants and consequences of implicit evaluations in a rape case. Situational (i.e. specifics of the rape case) and personal factors (i.e. rape myth acceptance) were demonstrated to influence both explicit and implicit judgments of the rape case. Moreover, sex of participant influenced participants’ implicit evaluations but affected explicit judgments only indirectly via the implicit evaluation. People’s gut response was shown to affect their explicit judgment of the case, and this effect was particularly pronounced for people with a low need for cognition (i.e. people who do not like to engage in effortful processing). The discussion focuses on the role of implicit cognition and implicit biases in judicial decision-making.  相似文献

DNA analysis has been widely used in the forensic field in order to contribute to identifying the perpetrator of a crime. Forensic investigation in sexual assaults usually focuses on locating and identifying biological fluids, followed by DNA analysis. The identification of certain compounds present in condoms can be useful to reconstruct the occurred event, especially in cases of sexual assaults where the DNA analysis did not show the presence of a male profile and where RNA analysis did not show the presence of sperm markers. Herein we describe the case of a woman reporting to be victim of sexual assault, who was not able to provide accurate information concerning the dynamics of the event; she remembered only forced penile–vaginal penetration by a single perpetrator. We performed short tandem repeat (STR) analyses and mRNA typing for forensic genetics testing on vaginal and rectal swabs collected on the victim, and Fourier-transform infrared spectroscopy (FTIR) followed by chromatographic analyses for the detection of condom compounds on the same swabs. The STR analysis showed only the victim’s genetic profile, and RNA analysis showed only the presence of vaginal and skin markers. In this situation, the identification of condom compounds residues on vaginal swabs became important as it complemented other collected evidences allowing the Court to reconstruct the events. A proposal of likelihood ratio (LR) calculation for the assessment of the weight of evidence in this case is described.  相似文献
