A Census of Medicolegal Death Investigation in the United States: A Need to Determine the State of our Nation’s Toxicology Laboratories and Their Preparedness for the Current Drug Overdose Epidemic

In 2007, the Bureau of Justice Statistics reported on 2004 data collected from the Census of Medical Examiner and Coroner Offices (CMEC). The CMEC was one of the first comprehensive reports on the state of the medicolegal death investigation system in the United States and included information on administration, expenditure, workload, specialized death investigations, records and evidence retention, and resources. However, the report did not include responses on questions that were related to toxicology such as specimen retention and type of testing. The purpose of this publication is to provide the community with toxicology laboratory-specific responses from nearly 2000 medical examiner and coroner (MEC) offices. Data obtained from a BJS CMEC public use dataset for any remaining information that was not reported in the 2007 BJS report were evaluated specific to the operation of toxicology laboratories within a MEC office or specific to toxicology testing. The CMEC includes information on average operating budget for MEC offices with internal or external toxicology services, budget for toxicology/microbiology services, respondents’ routine uses of toxicology analysis, toxicology specimen retention time, average turnaround times, use of computerized information management systems, and participation in federal data collections. These historical data begin to address the present state of our nation’s toxicology laboratories within the medicolegal death investigation system and their preparedness for the current drug overdose epidemic.     

Two-dimensional metric comparisons between dynamic bare footprints and insole foot impressions-forensic implications

Footwear may be found at crime scenes as physical evidence. Such footwear often has impression features of the wearer’s foot on the insole of the shoe. Scientific research and literature have established that footprints are distinct. This study compares two-dimensional measurements on bare footprints to foot impressions on insoles to determine if significant differences or similarities exist. Dynamic footprints were collected from 51 donors using the Identicator® Inkless Shoe Print Model LE 25P system. Seven foot length and width measurements were taken based on the Reel linear measurement method. Footprint measurements between bare footprints and foot impressions on the insoles were compared. Only two differences (p > 0.05) were observed between the various bare footprint and insole foot impression measurements on the right and left side for most of the measurements, CALC (p < 0.001) and A1 (p = 0.04). Bare footprint and insole A5 measurements on the left side were also significantly different (p = 0.015). The results of the study have implications in the forensic analysis of foot impression evidence on insoles in footwear in assisting with identifying the wearer of said footwear. Situations may arise in the forensic context when comparing the foot impression on the insole of footwear to a suspect’s bare footprint or a footprint from post-mortem remains. This study contributes to the scant literature available on the topic and to understanding the similarities and differences observed in the various linear measurements that may be utilized in the comparison process of footprint impressions on shoe insoles to bare footprints.     

How to share and utilise expertise in a police forensic department through externalisation and mutualisation

The technique of fire investigation is a forensic domain in which expertise and analogies play a central role. To learn how fire investigators use these analogies to support their work, we conducted an ethnographic study in a Swiss forensic police department. To propose a suitable knowledge-management strategy, we also evaluated the knowledge conservation and sharing within the department. Our results highlighted that actionable knowledge is registered mainly in the investigators’ memories of a few, very experienced, individuals. Without experience with fire-incident investigations, an agent generally requires help from a more experienced colleague, who will then use his memory to find a similar case, which can contribute to the solution of the ongoing one. The research also established that knowledge is exchanged orally during on-site investigations and that knowledge receivers are generally those who are present on the scene. Using these findings, we suggest building a case library to support the externalisation and sharing of knowledge.     

The Scharff technique: training military intelligence officers to elicit information from small cells of sources

ABSTRACT

Studies have demonstrated the efficacy of the Scharff technique for gathering human intelligence, but little is known about how this efficacy might vary among different samples of practitioners. In this training study we examined a sample of military officers (n?=?37). Half was trained in the Scharff technique and compared against officers receiving no Scharff training. All officers received the same case file describing two sources holding information about a terrorist attack. University students (n?=?74) took the role of the semi-cooperative sources. Scharff-trained officers adhered to the training as they (1) aimed to establish the ‘knowing-it-all’ illusion, (2) posed claims as a means of eliciting information, and (3) asked fewer explicit questions. The ‘untrained’ officers asked many explicit questions, questioned the reliability of the provided information, pressured the source, and displayed disappointment with the source's contribution. Scharff-trained officers were perceived as less eager to gather information and left their sources with the impression of having provided comparatively less new information, but collected a similar amount of new information as their untrained colleagues. The present paper both replicates and advances previous work in the field, and marks the Scharff technique as a promising technique for gathering human intelligence.     

论我国刑事错案责任追究制度的完善 ——以侦查机关为视角

我国刑事错案追究制度自实行以来,其运用的合理性以及有效性一直饱受争议。从侦查机关的视角考察,错案追责情况主要存在纠正程序不具体、追责程序透明度不高等相关问题。结合我国实际情况考虑,从内部制度与外部监督入手考虑设立独立的错案追究机关来进行解决是可行的,同时可从细化错案责任追究的相关程序、明晰实体责任性质的认定标准、建立健全办案质量终身责任追究制度和建立追责程序相关信息发布机制等方面来完善刑事错案追究制度。     

论闭路电视监控系统信息资料在侦查中的运用

近年来,随着我国经济的飞速发展以及人民群众防范意识的不断提高,闭路电视监控系统越来越普及,并得到了广泛运用。为了使闭路电视监控系统信息资料能够更好地运用到侦查破案中去,文章从闭路电视监控系统信息资料概述、信息资料在侦查破案中的运用、如何提高信息资料的使用效率以及使用中应注意的问题四个方面进行了论述,并提出了运用闭路电视监控系统信息资料的新理念、新方法。     

传承与发展：关于我国经侦运行机制的思考

改革开放30年来经济犯罪形势发生剧变的同时,我国经侦运行机制也随之不断完善。进入21世纪,现行经侦运行机制的不足之处日益显现,主要表现为警令不畅致使国家打击经济犯罪的决策难以彻底落实、执法活动中的地方保护主义异常严重、对经济犯罪的打防难以形成常态化的高压态势。为此,必须通过规范地方各级经侦机构建设、在全国范围内设置垂直领导的中央经侦机构等创新性举措完善现有经侦运行机制,从而以制度创新化解当前经侦部门面对的空前挑战。     

沉默权：一个无法沉默的话题——从我国刑诉法“应当如实回答”谈起

我国刑诉法规定了犯罪嫌疑人面对审讯人员的审讯：“应当如实回答”的义务,使其在刑事诉讼中处于不利的地位。是否赋予犯罪嫌疑人沉默权,由“口供本位”转向“物证本位”,彻底改变目前的侦查模式,是我国刑事诉讼法修改的一个不容忽视的重要问题。     

论侦查假说的三个支点

侦查假说是侦查人员在侦查破案过程中必不可少的思维方式。侦查假说具有多元性、层次性和开放性。侦查实践的终极目标是实现案件的侦破,侦查假说的正确与否决定着侦查工作的成败。侦查实践往往围绕侦查假说展开推理和论证。构建侦查假说,需要在时间层次、空间层次和人物层次之间进行综合考量,形成较完整的有关犯罪假说体系的三个支点。
