Drowning in the bath tub after choking: Unusual death, accident or suicide? Reconstruction of an unusual fall

A thirteen-year old girl attending a special school who had been suffering from genuine epilepsy for about one year was found dead completely clothed in the full bathtub in the bathroom of her parent's flat. The characteristic features of death by drowning but also signs of strangulation as well as a condition after shackling of the hands were found in the forensic post-mortem examination and autopsy. The putative strangulation instrument was a pair of tights which was floating in the bathwater. The hands were probably tied with the lace of a sneaker. In the further course of events, the inquiries and investigations initially commenced on the assumption of a capital crime gave reason to consider suicide. A reconstruction experiment under comparable external conditions indicates that this is possible. From a forensic-psychiatric point of view, an exacerbative mental crisis situation can be inferred as a final motive from the known personality configuration and the immediate circumstances. The tragic outcome in the final phase appears to have been determined by the additional complication of a provoked grand mal epilepsy attack. All in all, this hypothesis is the most plausible. However, subjective and objective observations do not rule out the possibility of homicide.     

Osler-Weber-Rendu syndrome--pathological manifestations and autopsy considerations

An 18-year-old university student with Osler-Weber-Rendu disease collapsed in the bathroom. Attempted resuscitation was unsuccessful. Her past history included recurrent epistaxes, mucosal telangiectasias, intracranial arteriovenous malformations with previous hemorrhage, a single pulmonary arteriovenous malformation, recent onset of grand mal seizures, and depression. There was a positive paternal family history. At autopsy the pulmonary arteriovenous malformation was confirmed. In addition, within the brain there were widespread areas of gliosis with hemosiderin deposition and small vascular malformations. No other significant abnormalities were detected and toxicological screening revealed only moderately elevated levels of carbemazepine. Death was attributed to epilepsy associated with glial scarring from previous microhemorrhages. The detection of vascular malformations in the lung or brain at autopsy should prompt careful examination of all tissues for similar lesions. Given the possibility of Osler-Weber-Rendu disease in such cases, fibroblast cultures should be undertaken to enable molecular studies to proceed. The heritable nature of this disorder necessitates accuracy of diagnosis at autopsy; once the diagnosis is confirmed family screening should be recommended.     

外伤性癫痫的法医学鉴定21例分析

为了探讨颅脑损伤后癫痫的法医学鉴定要点,对 21例颅脑损伤后癫痫出现发作者进行了现病史、既往史调查,并结合临床脑电图（ EEG）及 X线片、 CT片、 MRI片等影像学资料。结果发现外伤后癫痫常继发于严重的颅脑损伤,多以晚期发作为主,其发作性质决定于颅脑损伤的部位和程度,头皮 EEG和 24小时动态 EEG证实有异常癫痫样波存在,影像学检查有助于定性分析。结果提示：外伤性癫痫法医学鉴定必须以掌握外伤史及既往史为基础,结合 EEG、 CT、 MRI等检查方可作出正确鉴定。     

On the added value of forensic science and grand innovation challenges for the forensic community

In this paper the insights and results are presented of a long term and ongoing improvement effort within the Netherlands Forensic Institute (NFI) to establish a valuable innovation programme. From the overall perspective of the role and use of forensic science in the criminal justice system, the concepts of Forensic Information Value Added (FIVA) and Forensic Information Value Efficiency (FIVE) are introduced. From these concepts the key factors determining the added value of forensic investigations are discussed; Evidential Value, Relevance, Quality, Speed and Cost. By unravelling the added value of forensic science and combining this with the future needs and scientific and technological developments, six forensic grand challenges are introduced: i) Molecular Photo-fitting; ii) chemical imaging, profiling and age estimation of finger marks; iii) Advancing Forensic Medicine; iv) Objective Forensic Evaluation; v) the Digital Forensic Service Centre and vi) Real time In-Situ Chemical Identification. Finally, models for forensic innovation are presented that could lead to major international breakthroughs on all these six themes within a five year time span. This could cause a step change in the added value of forensic science and would make forensic investigative methods even more valuable than they already are today.

Forensic and medical evaluation of vascular malformations of the brain in cranio-cerebral trauma

A classification of vascular malformations (VM) is defined in the article including a differentiation between their macroscopic and histological variations; an independently-authors-observed case of arterial-and-venous malformation (AVM) in a minor cranial-cerebral trauma (CCT) is described. Published data reflecting the forensic-and-medical value of AVM and cavernous malformations as well as of telangectasias and of arterial-and-venous fistulas in minor head traumas are analyzed. Issues of the forensic-and-medical expertise of VM and remote consequences of CCT are under consideration. VM are assessed in CCT patients with epilepsy and other pathologies. An algorithm of the forensic medical expertise of VM is suggested.     

Forensic science and criminal justice: An analysis of curricular models

The multi-disciplinary field of forensic science frequently finds its academic home within criminal justice programs. After examining the reasons for this academic linkage, an analysis of criminal justice curricular models and courses was undertaken to assess their applicability to forensic science education and careers. The authors concluded that the relationship between criminal justice and forensic science can be mutually beneficial; however, most criminal justice programs do not provide adequate preparation for meaningful careers in forensic science.     

Behind closed doors: the effect of pretrial publicity on jury deliberations

Abstract

Effective treatment of aggressive behaviour and accurate release decision making are necessary components of adequate clinical practice in forensic psychiatric units. Unfortunately, methods to identify treatment targets and ameliorate aggressive behaviour have developed at a slower pace than risk assessment technologies. Recent progress on the identification of offence paralleling or functionally equivalent behaviour offers a framework for individually tailored treatment and idiographic release decision making, although empirical scrutiny of this approach is inadequate. This paper describes an examination of the relationship between aggressive behaviour prior to admission with aggression during inpatient psychiatric treatment, and reconviction for violent offending following discharge. Results showed a relationship between pre- and post-admission aggression but no relationship between aggression during inpatient psychiatric treatment with either pre-admission aggressive behaviour or violent recidivism. These findings indicate the importance of state psychological variables, specifically those states affected by symptoms of psychiatric illness, as well as environmental activators and inhibitors of violence that operate within the hospital. These require inclusion in an adequate functional analysis of aggressive behaviour for forensic psychiatric patients.
