Perimortem Skeletal Sharp Force Trauma: Detection Reliability on CT Data, Demographics and Anatomical Patterns from a Forensic Dataset.

Biology (Basel) 2022 Apr 26;11(5). Epub 2022 Apr 26.

Department of Physical Anthropology, Institute of Forensic Medicine, University of Bern, 3008 Bern, Switzerland.

The increasing importance of trauma analysis by means of postmortem computed tomography (PMCT) is insufficiently reflected in forensic curricula, nor are best practice manuals available. We attempt to detect sharp force bone lesions on PMCT of closed forensic cases with the aims of assessing errors and pointing out patterns in anatomical location and manner of death (MOD). We investigated 41 closed sharp force fatality cases, with available PMCT and forensic reports. Read More

Am J Forensic Med Pathol 2022 Jun 28;43(2):110-116. Epub 2022 Jan 28.

From the Medical University of South Carolina, Charleston, SC.

Abstract: After high-profile events involving firearms, gun violence often becomes the center stage of public discourse with national media attention, overshadowing less common causes of homicidal deaths, such as sharp force injury, blunt trauma, and asphyxia. A retrospective analysis of all cases referred for medicolegal autopsy to the Medical and Forensic Autopsy Division of the Department of Pathology and Laboratory Medicine at the Medical University of South Carolina from 2013 to 2018 documented 793 deaths where the manner was classified as homicide. Of these, 18% (144) of the deaths were caused by non-firearm-inflicted injuries. Read More

J Forensic Leg Med 2021 Apr 27;79:102147. Epub 2021 Feb 27.

Department of Anatomical, Histological, Forensic and Orthopaedic Sciences, Sapienza University of Rome, Rome, Italy. Electronic address:

In modern times crossbow - a ranged weapon diffused during Middle Ages - is increasing its popularity in recreational hunting and sports; crossbow bolts have a great penetration capacity, despite their low initial velocity. Great concerns emerge when considering that notwithstanding crossbow is a potentially lethal distance weapon, it is easy to obtain without having to undertake any tests on the buyer's mental or physical health. Although rare, crossbow injuries can be challenging for the forensic pathologist due to great similarities with other wounds pattern (gunshots wounds or injury due to sharp force). Read More

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.

Companion animal abuse is an issue that concerns not only veterinarians and law enforcement agencies but also society in general. Animals that die under suspicious or violent circumstances should be submitted to reference laboratories for a postmortem examination by veterinary forensic pathologists trained to recognize animal abuse. Nevertheless, the low notification rate of such cases in Spain may explain the country's lag in the development of veterinary forensics and the limited information available on animal abuse epidemiology in comparison with other countries.
