History of forensic science

BACKGROUND: To strengthen the nation's use of forensic science and advance professional practice, forensic practitioners and scientists in the Organization of Scientific Area Committees (OSAC) develop standards in forensic science. The Forensic Nursing Subcommittee was created by OSAC in 2021 to develop standards that improve patient outcomes through delivery of consistent practice guidelines, evidence-based techniques for preservation of evidence, and accurate representation of practice and examination findings...

The well preserved skeleton of Joseph Huber, a very well-known historical character of the 19th century Munich, also nicknamed "Finessen-Sepperl", is the starting point of the reconstruction of life and death of this historical individual. He was known as a postilion d´amour (love's messenger) of the Royal Bavarian capital with numerous comments and anecdotes and a few biographical sketches that indicate he remained well until the last few years of his life where requests for his duties lessened. The skeleton shows a small-sized male individual with almost complete loss of teeth, but otherwise very well-mineralized bone, having suffered from three episodes of trauma - an old-healed incomplete femoral neck fracture leading to severe osteoarthrosis, a clavicle fracture of the medial third with a few weeks old callus formation, and fresh serial rib fractures along with severe skull trauma with fractures of the os temporale and petrosum, presumably leading to intracranial bleeding and finally death...

PURPOSE: The most prevalent method of carbon monoxide (CO) suicide is inhalation of vehicle exhaust (VE). However, a new method of CO suicide has recently emerged involving charcoal burning (CB) in a confined space to produce fatal CO levels. This method has been reported from countries in Asia, associated with economic instability and media reporting of high-profile celebrity cases. The current study was undertaken to analyze rates and characteristics of CB suicides in South Australia (SA) for comparison with respect to their characteristics and scene, autopsy and toxicology findings...

Introduction: Qatar established its Community Forensic Mental Health Team (CFMHT) in 2019 as part of the region's first comprehensive forensic psychiatry service. We present here the data on clinical and offending outcomes since its establishment and compare this with data from before the service was established. Objectives: To compare clinical and offending outcomes in mental health patients with criminal offending histories in Qatar before and after the establishment of CFMHT. Methods: This is a retrospective study comparing the socio-demographical characteristics, clinical outcome and recidivism measures of forensic patients, under the CFMHT for the last 2 years with data from a similar period before the services were in place...

Pediatric population represents the most vulnerable and at risk for unintentional poisoning, with children younger than 6 years old accounting for nearly half of poison exposures. Poisoning is a time-dependent emergency. The need to reach a scientific agreement on diagnostic protocol and treatment seems to be crucial to reduce morbidity and mortality. Starting from a buprenorphine pediatric intoxication case, this article highlights the limits and pitfalls of the traditional diagnostic approach. Diagnosis of drug intoxication was achieved after several days when an in-depth diagnostic investigation became necessary and complete forensic toxicological analyses were performed...

The comparative examination of different groups of sexual homicide offenders (SHOs) is currently limited. To expand our understanding of Chinese sexual homicides, this study aimed to distinguish between the modus operandi (MO) characteristics of repeat (i.e., with previous arrest and/or conviction) and nonrepeat (i.e., without previous arrest and/or conviction) offenders. Data were gathered from police arrest records, court documents, and published case reports in mainland China, covering a 31-year period (1988-2018)...

Anaphylaxis is a rare but well-known cause of sudden unexpected death, although data from forensic autopsies in anaphylactic deaths are limited. Herein, a retrospective study of a series of allergic deaths from 2009 through 2019 in Shanghai, China, was conducted to investigate the demographic, medical, and forensic pathological characteristics of fatal anaphylaxis to improve medicolegal understanding on anaphylactic death. Sixty-two autopsy cases of anaphylactic death were registered in this study. Males dominated the cases (74...

We examined the interrelationships between psychopathy, changes in general criminal attitudes, and community recidivism in a sample of 212 men who attended an institutional sexual offense treatment program (SOTP) and were followed for an average of 12.73 years post-release. The men completed a self-report measure of general criminal attitudes, the Criminal Sentiments Scale, as part of routine SOTP service delivery, Psychopathy Checklist-Revised (PCL-R) ratings were completed via file review, and recidivism data were obtained from official criminal records...

Evidence of an insulin overdose is very complicated in the medico-legal field. The analysis and subsequent interpretation of results is complex, especially when treating postmortem blood samples. The instability of insulin, the special pre-analytical conditions and the absence of specific analytical methods has led most laboratories not to analyze insulin in their routine with a consequent underestimation of cases. This paper aims to assess the difficulties associated with the analytical characterization of insulin by describing a case that typically represents most of the inconveniences encountered following a suspected insulin overdose...

This study aimed to compare the concentration of various xenobiotics in both cerebrospinal fluid (CSF) and blood. We examined 175 autopsy cases covering a wide range of ages, causes of death, and drug ingestion histories, with cerebrospinal fluid and blood samples available for toxicological testing. Analytes studied included opioids, benzodiazepines, antidepressants, antipsychotics, and illicit substances such as cannabinoids, stimulants and new psychoactive substances, including synthetic cathinones and synthetic cannabinoids...

The Internet plays a pervasive role in modern life including the expression of human sexuality and sexual offending. A range of online sexual activities may be of interest in forensic mental health evaluations (FMHE), including those which are clearly illegal or those which are legal but functionally problematic. Online sexual offenses will clearly prompt forensic evaluators to consider the role of the Internet in these offending behaviors. The Internet may also be relevant in forensic evaluations of contact sexual offending including informing on history of mixed or cross-over offending, and Internet-facilitated contact offenses...

"Excited Delirium Syndrome" (ExDS) is a controversial diagnosis. The supposed syndrome is sometimes considered to be a potential cause of death. However, it has been argued that its sole purpose is to cover up excessive police violence because it is mainly used to explain deaths of individuals in custody. In this paper, we examine the epistemic conditions giving rise to the controversial diagnosis by discussing the relation between causal hypotheses, evidence, and data in forensic medicine. We argue that the practitioners' social context affects causal inquiry through background assumptions that enter inquiry at multiple stages...

Isotopic analysis of human tooth enamel can provide life history information useful in forensic identification. These applications depend on the availability of reference data documenting isotopic values for individuals with known life history and on the comparability of data from reference and case work samples. Here we build on previous methodological research, which has largely focused on paleontological and archaeological samples, and conduct experiments using enamel from modern human teeth targeting three sample preparation variables (sample particle size, storage conditions, and chemical pretreatments)...

BACKGROUND: In forensic toxicology, positive immunoassay (IA) test results do not hold forensic validity and need to be confirmed with mass spectrometry (MS). On the other hand, a negative result is a strong indication that the drug and/or the drug metabolites are not present in the sample and that confirmatory analyses are not necessary. Consequently, a negative IA result must have forensic validity since it can be admitted in court during a trial. OBJECTIVES: Screening cutoffs for the analysis of hair samples using immunoassays (IAs) were retrospectively optimized based on the Society of Hair Testing (SoHT) confirmation cutoffs and the utility of the test for forensic applications was discussed...

The increasing use and misuse of gabapentin pose a major risk to public health and traffic safety. Gabapentin has been approved by the Food and Drug Administration (FDA) since 1993 for adjunctive therapy in the treatment of epilepsy and neuralgia but is increasingly being prescribed for numerous off-label uses including insomnia, anxiety, depression, and migraine. Reported side effects include blurred vision, drowsiness, and loss of coordination. Driving behaviors such as exiting the lane of travel and crashes have been reported in connection to drugged driving investigations concerning gabapentin...

Atherosclerosis is an inflammatory disease that, in its more developed stages, can lead to the calcification of fatty plaques on the walls of arteries, resulting in the appearance of new bone elements. It is a condition that has been studied and documented little in the context of paleopathology, especially in the framework of forensic anthropology. This article analyzed the skeletal remains of 71 individuals (35 females and 36 males) from the Luís Lopes Identified Collection of the National Museum of Natural History and Science in Lisbon, 31 of whom had an autopsy report...

Grigori Yefimovich Rasputin, a confidant of Tsar Nicholas and his wife, was murdered by Prince Yussupov and his co-conspirators in the cellar of the prince's Moika Palace in St Petersburg, Russia, on the evening of December 30th, 1916 (December 17th in the Russian calendar). The narrative of his death is largely based on Prince Yussupov's published memoirs and has Rasputin being poisoned with cyanide, shot, bludgeoned, and finally drowned. A review of the available forensic material, however, shows a photograph with a contact gunshot wound to Rasputin's forehead...

Methcathinone, a psychoactive substance with stimulant properties, has raised concerns in recent years due to its presence in urine screenings, even among individuals with no history of drug abuse. To prevent misjudgment, this work aims to explore the source of methcathinone in urine. A total of 58 urine samples tested positive for methcathinone in the National Taiwan University Hospital cohort, with 27 linked to illicit drug use and 31 from individuals with no drug use history. Co-occurrence analysis revealed a strong association between methcathinone and over-the-counter cold medications containing pseudoephedrine or ephedrine...

Forensic evaluators are increasingly called upon to review online collateral information, including social media posts, web forum posts, chat histories, and other sources such as manifestos. This information is especially vital when assessing members of a virtual community such as that of the involuntary celibate, or incel community. While this new wealth of information can add valuable context to the forensic assessment, it presents unique challenges for the evaluator including challenges with authenticity and interpretation...

The basic initiative related to this study is derived from the fact that systemic lupus erythematosus (SLE) is a unique and fertile system science subject. We are, however, still far from understanding its nature. It may be fair to indicate that we are spending more time and resources on studying the complexity of classified SLE than studying the validity of classification criteria. This study represents a theoretical analysis of current instinctual SLE classification criteria based on "the causality principle...
