Police reporting in cases of sexual assault - a 10-year study of reported cases, unreported cases, and cases with delayed reporting.

The aim of this study was to identify characteristics of reported, later-reported and unreported cases of sexual assault. All cases with female complainants (> 15 years) of sexual assault, who had been examined at the Centre for Victims of Sexual Assault (CVSA) in the Region of Southern Denmark in a 10-year period, were included. Retrospective data were collected from medico-legal examination reports and police reports. Descriptive bivariate analysis and logistic analysis were performed. Forensic pathologists examined 850 complainants of sexual assault in 2009-2018, of which 753 cases were included in this study. Of these, 191 cases (25%) were initially not reported to the police, but 53 women (7%) filed a police report, days, weeks or months later. There was a higher relative risk (RR) of not-reporting for young adults, for single women, if the accused was well known to the complainant, if the complainant experienced amnesia, or if there had been some degree of consensual physical interaction at time of the incident but before the assault. The non-reporters also showed a higher degree of delayed examination. The later-reporters only differed from the non-reporters in one parameter - they had a higher degree of partial amnesia. Interestingly, injuries (ano-genital or other) or verbal/physical resistance was not associated with reporting tendency, reflecting the modus of the local judicial system. The opportunity of a reflection period after a high-quality forensic examination, which is not dependent of police involvement, is essential for sexual assault complainants. Furthermore, education and guidance of victims and of the police and judicial system on the unique nature of sexual assault cases is important.

Stranger rape; distinctions between the typical rape type and other types of rape. A study based on data from Center for Victims of Sexual Assault.

OBJECTIVE: The aim of this descriptive cohort study was to characterize stranger rape compared to other types of rape. METHOD & MATERIALS: All cases of women aged 12 years or older, who contacted a Center for Victims of Sexual Assault in the region of Southern Denmark and underwent a forensic examination in 2018, were collected and analyzed. Descriptive frequencies, Pearson's χ2-test and Fisher's exact-test were performed. RESULTS: Compared to other types of rape, stranger rape were reported to the police more frequently, earlier and more frequently independently, without contact to family, friends or other authorities. In cases of stranger rape women were exposed to threats and violence more often, and clinical findings were found to coincide with the women's report more frequently. Regarding the offenders' level of planning, it was not possible to find significant differences between stranger rape and other rape types by comparing frequencies of the offenders' use of condoms and weapons and/or other remedies as surrogate markers for degree of planning. CONCLUSION: There were several significant characteristic differences between stranger rape and other types of rape. Characterizing the 'archetypical rape' in opposition to other and more frequent types of rape, may give the public, the police, the courts and aid organizations the background needed to understand the importance of rape typologies when handling cases of sexual assault.

Characteristics of mechanical CPR-related injuries: A case series.

INTRODUCTION: Chest compression is regarded as a vital component of CPR and should be initiated immediately upon recognition of cardiac arrest in order to preserve circulation and thereby maintaining vital functions. Mechanical devices for CPR are still more common in the pre- and in-hospital treatment of cardiac arrest. Injuries due to treatment with these are known to occur. The aim of this case series was to identify and characterize the injury pattern in patients who had received mechanical CPR with focus on the visceral injuries. METHOD: From 2016 to 2018, we prospectively included all patients who had received out-of-hospital mech-CPR with a LUCAS device in the Region of Southern Denmark (RSD) who were subsequently autopsied. Both hospital and forensic autopsies were included. We excluded cases with age less than 18, trauma immediately preceding the cardiac arrest, or known pregnancy. RESULTS: A total number of 50 cases were included in this study. Overall, 38 (76%) had injuries. In the remaining 12 cases (24%) we found neither skeletal or visceral injuries nor any bruising of the chest. 11 (22%) had visceral injuries. Four patients suffered abdominal injuries. The remaining patients had thoracic injuries only. In five cases, the pathologist considered the injuries life-threatening had the patients otherwise survived. These five cases were less than 55 years old and had no known or observed conditions which could explain the extend of injury. CONCLUSION: We found five iatrogenic injuries which in itself could have been fatal had the patients survived the incident. It is of great importance for the forensic pathologists to be aware of the possible types of injuries and their severity caused by compressions when dealing with patients treated with mechanical CPR as they are both diverse and can be extensive.

Sudden death due to diabetic ketoacidosis following power failure of an insulin pump: Autopsy and pump data.

PURPOSE: To report a case in which autopsy findings and data from an insulin pump illustrate the course up to the death of a 31-year-old man with a history of type 1 diabetes mellitus who was found dead in his apartment with his insulin pump disassembled and placed in another room. METHODS: Autopsy findings including histological, toxicological and biochemical examination are presented. Postmortem download of data from the insulin pump gave the history of the pump, which included blood glucose, insulin bolus, carbohydrate intake and the time course in the days to death, and the pump settings were recorded. For this case report, police reports on the death as well as hospital records were also reviewed. RESULTS: At the patch for the insulin pump, nothing abnormal was found. Biochemical analysis showed glucose of 35 mmoL/L in vitreous humor fluid indicating antemortem hyperglycemia, and ketone bodies in the blood of 11.0 mmoL/L indicating ketoacidosis. Acute pulmonary hemostasis, chronic fat accumulation in the liver and acute fat accumulation in the kidneys were histological detected. There were no signs of late diabetic complications such as nephropathy or cardiovascular disease in the tissues. Insulin pump data showed that after three alarms, a power failure of the pump occurred leading to discontinuing insulin delivery, and about 48 h before the deceased was found dead, his body was depleted of insulin. CONCLUSION: The cause of death is believed to be diabetic ketoacidosis due to completely lack of insulin because of power failure of the insulin pump, which therefore has been a decisive factor in the cascade of events that led to death. The case is, to our knowledge, the first to illustrate a death caused by diabetic ketoacidosis which is supported by autopsy findings and by data of an insulin pump up to the time of power failure. It is a strong example of usefulness of postmortem download of data from insulin pumps to help determine the cause of death among diabetics. Forensic pathologists should therefore review data and history of the pump systematically.

Prehospital cardiopulmonary resuscitation with manual or mechanical chest compression: A study of compression-induced injuries.

OBJECTIVE: Concerns for iatrogenic injuries associated with cardiopulmonary resuscitation led us to investigate the extent and the pattern of chest compression-related injuries in patients subjected to either mechanical and/or manual cardiac compression. METHOD: In a retrospective study, we performed a manual review of all prehospital discharge reports, in-hospital records, and autopsy reports for evidence of injuries related to chest compression. We included all patients receiving physician-administrated treatment for out-of-hospital cardiac arrest in the Region of Southern Denmark from 2015 to 2017. RESULTS: Eighty four patients undergoing manual and mechanical chest compression and 353 patients with manual chest compression only were included. Unadjusted, mechanical chest compression as an adjunct was associated with a higher risk of injuries than manual chest compression (P < 0.001, odds ratio, OR 3.10). Adjusted for the duration of compression, this difference waned. Visceral injuries were more frequent in patients receiving mechanical chest compression even when adjusted for the duration of compression, age, sex, body mass index and anticoagulant therapy (P < 0.001, OR 29.84). We found a higher incidence of potentially life-threatening injuries in patients receiving mechanical chest compression. The occurrence of injuries overall was associated with the duration of chest compression (P = 0.02, OR 1.02). CONCLUSION: Mechanical chest compression as an adjunct to manual chest compression was strongly associated with potentially life-threatening visceral injuries. The duration of chest compression was associated with injury. Our results suggest that mechanical chest compression should only be applied in situations where manual chest compression is unfeasible.

The significance of the forensic clinical examination on the judicial assessment of rape complaints - developments and trends.

OBJECTIVE: The aim of this study was to investigate the role of the forensic clinical examination in the judicial assessment made by the Prosecution Service in cases of rape. METHODS: All cases of police-reported sexual assault in the county of Funen, Denmark in a six-year period were reviewed, and the retrospective data was collected. Cases in which a forensic clinical examination was performed were included. RESULTS: The Prosecution Service in the county of Funen received 348 police-reported rape cases and of these 184 cases were included. The Prosecution Service stated that the forensic clinical examination (FCE) was important for the decision-making process in approximately half of the cases. The Prosecution Service finding an FCE important due to the presence of relevant findings was significantly associated with the case going to trial, whereas importance due to absence of relevant findings was significantly associated with the cases not going to trial. The only single factor associated with a case going to court and a guilty verdict was an FCE of the alleged perpetrator. There were no crude associations between any other factors i.e. the type of assault, victim injuries or alcohol consumption. In a logistic regression model, however, it was significantly more likely (p < 0.05) that a forensic clinical examination of the victim was used in the Prosecution Service's decision if there were both anogenital and extra-genital injuries documented, that could originate from the alleged crime. The odds were 7.83 times higher compared to if no injuries were detected. The Prosecution Service's use of the clinical examination in their argumentation of the decision of a rape complaint has been significantly increasing from 2003 to 2015. CONCLUSION: The results of the first in-depth analysis of the overall importance of a forensic clinical examination in cases of rape and sexual assault shows that we need to continuously focus on the documentation of sexual assault, as documentation is part of the decision-making process at all stages of the judicial process.

Life-Threatening and Suspicious Lesions Caused by Mechanical Cardiopulmonary Resuscitation.

Chest compression devices for mechanical cardiopulmonary resuscitation (CPR) have become more common. Here, we report the case of a young woman who attempted resuscitated with LUCAS™2 after she was found unconscious at home. At autopsy, we found extensive intramuscular hemorrhages in posterior neck, between the scapulae, and in the lumbar region. Investigation of internal organs showed injuries to the lung, spleen, and kidney. The extension of the injuries gave rise to suspicion of homicide by smothering, which police investigation subsequently did not support. The pattern of injury could be attributed to automatic compression decompression CPR with LUCAS™2.The injuries may have been lethal had the patient survived. For the forensic pathologists, it is important to remain updated on developments in treatment techniques to avoid pitfalls when interpreting injury.Larger studies, prospective or retrospective, may be able to qualify the possible risks of automatic compression decompression CPR even further.

Suffocation caused by plastic wrap covering the face combined with nitrous oxide inhalation.

Suicide using a combination of a plastic bag over the head and inhalation of a non-irritating gas, such as helium, argon or nitrogen, has been reported in the literature. Here an unusual suicide method in a 17-year old man by suffocation from covering the face with household plastic wrap, combined with nitrous oxide inhalation, is presented. The case was reviewed based on police, autopsy and hospital reports. A PubMed search for scientific literature related to nitrous oxide abuse and suicide by suffocation was performed and our findings discussed in relation to the scientific literature found. The deceased was a 17-year old man who was found with the nose and mouth closed with a piece of kitchen plastic wrap. The plastic wrap had been removed prior to autopsy. Autopsy findings were suggestive of asphyxia, but were otherwise negative. Nitrous oxide was detected in the brain and lung tissue with headspace-gas chromatography-mass spectrometry (headspace-GCMS). The cause of death was assumed to be suffocation caused by plastic wrap covering the face, combined with nitrous oxide inhalation. Suicide was suspected because of a history of depression for several months. Nitrous oxide, also known as laughing gas, has a euphoric effect and is used as a recreational inhalant drug that can be purchased legally. Deaths caused by recreational nitrous oxide abuse are rare but may occur if used in combination with a plastic bag over the head. This is the first report of suicide by suffocation by external obstruction combined with nitrous oxide inhalation.

Trends in child sexual abuse cases referred for forensic examination in Southern Denmark from 2000 to 2011 - Did the 'Tønder-case' have an impact?

In 2005 a serious case of child sexual abuse from the region of Southern Denmark was revealed to the Danish public. The case became known as the 'Tønder-case'. It was the first in a series of 4-5 serious cases of child maltreatment in Denmark, cases which spurred heavy public debate. In this study all the cases of child sexual abuse referred for forensic examination in a 12 year period, a total of 368 cases, were systematically evaluated. In order to identify any trends that could be correlated to an impact of the 'Tønder-case', cases from 2000 to 2002 and cases from 2009 to 2011 underwent an in-depth analysis. In the 12 year period there was a significant increase in numbers of cases. In the subgroups, comprised of 113 cases meeting the inclusion criteria, we found a significant increase in the frequency of cases involving incest and systematic abuse, as well as an uncorrelated increase in the frequency of cases where children were placed in foster care prior to the examination. These results were countered by a significant decrease in the number cases police reported child sexual abuse in the same period. The possible impact that cases like the 'Tønder-case' and the following press coverage may have on disclosure and the handling of this type of case by authorities is discussed, as well as further perspectives of extensive press coverage.

Patterned genital injury in cases of rape--a case-control study.

A pattern of genital injury that separates trauma seen in sexual assault cases from trauma seen following consensual sexual intercourse has been a matter of debate. This study aimed at clarifying the question by eliminating as many confounders as possible in a prospective, case-control setup. A total of 98 controls and 39 cases were examined using the naked eye, the colposcope and toluidine blue dye followed by colposcopy. The overall frequency of having at least one lesion was strikingly similar in the two groups, but cases had significantly more abrasions, a trend towards more haematomas and a higher frequency of multiple lesions. Cases had a higher frequency of lesions in locations other than the 6 o'clock position. Our data suggests that cases have larger, more complex lesions. In conclusion, this study has confirmed the existence of different patterns of genital lesions. Background data for detection of genital lesions using the three most commonly used techniques is provided. These results will aid in the interpretation of findings seen when examining sexual assault victims.

Colposcopic photography of genital injury following sexual intercourse in adults.

The aim of this study was to evaluate interpretations and the reproducibility of interpretations when looking at colposcopic photographs in a forensic setting, as well as discussing some of the dilemmas and pitfalls of forensic colposcopic photography. A total of 316 colposcopic photographs from 51 women taken on three occasions following consensual sexual intercourse, and 78 colposcopic photographs from 39 rape victims, were evaluated by four different observers. Photographs were taken in the same setting, by the same group of investigators, before and after application of toluidine blue dye. The overall Kappa-value for the four observers' judgment of lesion vs. no lesion was 0.41 which can be interpreted as moderate agreement. Intra-observer agreement was calculated for two of the observers looking at photographs with a 10 months' time-gap, and the Kappa-values were 0.41 and 0.52. Positive and negative predictive values of the photographs were 82 and 81 % respectively. This study demonstrates relatively poor reliability of colposcopic photography. Some would argue that this makes colposcopic photography a low-quality method of evaluation and that forensic science should aim for higher standards because of its use in court. Others would argue that as long as the limitations of a scientific method are acknowledged then it is still eligible for use. The moderate agreement and accuracy stresses the need for quality control in the gynecological part of a rape examination. Colposcopic photography also provides a good option for supervision and teaching in an ethically difficult setting. It strengthens the legal rights for both victim and perpetrator.

Detection of spermatozoa following consensual sexual intercourse.

INTRODUCTION: In cases of sexual assault, the finding of semen can provide crucial evidence. The presence of spermatozoa serves as proof of a sexual act and may give the identity of the alleged perpetrator through DNA-profiling. In most western countries, there are guidelines for standardized examinations of sexual assault victims. For an objective evaluation of the findings, substantial knowledge of aspects regarding consensual sexual intercourse is crucial. The aim of this study was to examine detection frequencies and genital sampling sites of spermatozoa following consensual sexual intercourse. METHODS: In a prospective setting, 60 women underwent forensic examination following consensual sexual intercourse. Specimens were obtained from the external genitalia, the posterior fornix and the cervical canal, and examined using the Papanicolau stain and standard light microscopy. RESULTS: We found that 88% of possible cases were positive for spermatozoa. The posterior fornix was significantly better than the other sites for detection of spermatozoa and the number of spermatozoa decreased significantly over time. In a large sub-group of women who reported that no intra-vaginal ejaculation had taken place during their latest intercourse, a significant number (14%) had spermatozoa in the vagina. CONCLUSION: Spermatozoa were best recovered from the posterior fornix, but spermatozoa were also present on swabs taken from the external genitalia. Detection of spermatozoa is thus possible in cases where a speculum examination is denied.

Nature, frequency and duration of genital lesions after consensual sexual intercourse--implications for legal proceedings.

OBJECTIVE: The purpose of this study was to make a normative description of the nature and duration of genital lesions sustained during consensual sexual intercourse, using the three most commonly used techniques; visualisation using the naked eye, colposcopy and toluidine blue dye followed by colposcopy. METHODS: Ninety eight women were examined within 48 h of consensual sexual intercourse. Fifty of the women were examined twice again within the following 7 days of sexual abstinence after the first examination. RESULTS: The participants had a median age of 22.4 years and 88% were nulliparous. Lesions were frequent; 34% seen with the naked eye, 49% seen with colposcopy and 52% seen with toluidine blue dye and subsequent colposcopy. The lesions lasted for several days; the median survival times for lacerations were 24, 40 and 80 h, respectively. CONCLUSIONS: The legal implications of these findings are that genital lesions by themselves do not corroborate a rape complaint. Genital lesions may, however, corroborate specific details of a case and should be documented as carefully as any other lesion in rape complaints.
