Through fire and flames: post-burning survival and detection of dismemberment-related toolmarks in cremated cadavers.

Int J Legal Med 2021 May 21;135(3):801-815. Epub 2020 Oct 21.

Departamento de Medicina Legal Psiquiatría y Patología, Laboratorio de Antropología y Odontología Forense, Madrid, Spain.

During a homicide investigation in which fire has been used to reduce the size of the cadaver and conceal the evidence of injuries, the identification of perimortem trauma presents a challenge, in particular in cases when the perpetrator has dismembered the body followed by burning the remains. It is therefore important to understand the effects which heat causes on fresh bone. The aim of this paper is to perform a pilot study on the survival ratio of toolmarks in different anatomical regions associated with dismemberment, and a descriptive analysis of the variables that may potentially influence the post-burning survival and detection.

Toward a global and reproducible science for brain imaging in neurotrauma: the ENIGMA adult moderate/severe traumatic brain injury working group.

Brain Imaging Behav 2021 Apr;15(2):526-554

Department of Brain Sciences, Imperial College London, London, UK.

The global burden of mortality and morbidity caused by traumatic brain injury (TBI) is significant, and the heterogeneity of TBI patients and the relatively small sample sizes of most current neuroimaging studies is a major challenge for scientific advances and clinical translation. The ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) Adult moderate/severe TBI (AMS-TBI) working group aims to be a driving force for new discoveries in AMS-TBI by providing researchers world-wide with an effective framework and platform for large-scale cross-border collaboration and data sharing. Based on the principles of transparency, rigor, reproducibility and collaboration, we will facilitate the development and dissemination of multiscale and big data analysis pipelines for harmonized analyses in AMS-TBI using structural and functional neuroimaging in combination with non-imaging biomarkers, genetics, as well as clinical and behavioral measures.

Beer stein blast to the head a rare case of combined blunt and sharp force trauma.

Int J Legal Med 2020 Sep 6;134(5):1791-1796. Epub 2020 Jul 6.

Institut für Rechtsmedizin, Ludwig-Maximillians Universität München, Munich, Germany.

Cases of combined blunt and sharp force trauma to the head caused by one striking tool are rare. When beer steins are used as an assault weapon, they can cause blunt traumas upon initial contact phase. If the impact force exceeds the mechanical stability of the beer stein, it breaks into several sharp-edged pieces, which then can cause sharp force trauma injuries due to the interaction between the head and the stein fragments.

Forensic Sci Int 2020 Sep 20;314:110373. Epub 2020 Jun 20.

Bharti School of Engineering, Laurentian University, Sudbury, Ontario, Canada. Electronic address:

Forensic anthropologists have traditionally relied on a qualitative scale (mild, moderate, severe) for describing the forces required to generate a bony injury; however, recently efforts have focused on providing more quantitative data. The current study considers the effects of blade angle on the peak force, average force, and work measured during an instrumented sharp force impact. Sixty-two porcine side ribs were stabbed with the long axis of the blade perpendicular to the convex surface and the blade edge in one of three orientations (0°, 45°, 90°). Read More

Improved medical treatment could explain a decrease in homicides with a single stab wound.

Forensic Sci Med Pathol 2020 09 4;16(3):415-422. Epub 2020 May 4.

Department of Forensic Medicine, Faculty of Health Sciences, University of Copenhagen, Frederik V's vej 11, 2100, Copenhagen, Denmark.

Since the 1990s, there has been a reduction in the homicide rate in Denmark and other Western countries. Our hypothesis is that part of the decrease in the sharp force homicide rate can be explained by better and faster medical treatment over time, and we explore this via stab wound homicides, the largest group of homicides in Denmark. To investigate our hypothesis we undertook an epidemiological study of 428 stab wound homicides in Denmark 1992-2016 based on autopsy reports with registration of stab wounds, quantification of injury severity, treatment intensity and survival time.
