Human Identification Using Automatic and Semi‐Automatically Detected Facial Marks

Continuing advancements in the field of digital cameras and surveillance imaging devices have led law enforcement and intelligence agencies to use analysis of images and videos for the investigation and prosecution of crime. When determining identity from photographic evidence, forensic analysts perform comparison of visible facial features manually, which is inefficient. In this study, we will address research efforts to use facial marks as biometric signatures to distinguish between individuals. We propose two systems to assist forensic analysts during photographic comparison: an improved multiscale facial mark system in which facial marks are detected automatically, and a semi‐automatic facial mark system that integrates human knowledge within the improved multiscale facial mark system. Experiment results employ a high‐resolution time‐elapsed dataset acquired at the University of Notre Dame between 2009 and 2011. The results indicate that the geometric distributions of facial mark patterns can be used to distinguish between individuals.     

Evaluation of GLOCK 9 mm Firing Pin Aperture Shear Mark Individuality Based On 1,632 Different Pistols by Traditional Pattern Matching and IBIS Pattern Recognition

Over a period of 21 years, a number of fired GLOCK cartridge cases have been evaluated. A total of 1632 GLOCK firearms were used to generate a sample of the same size. Our research hypothesis was that no cartridge cases fired from different 9‐mm semiautomatic GLOCK pistols would be mistaken as coming from the same gun. Using optical comparison microscopy, two separate experiments were carried out to test this hypothesis. A subsample of 617 test‐fired cases were subjected to algorithmic comparison by the Integrated Ballistics Identification System (IBIS). The second experiment subjected the full set of 1632 cases to manual comparisons using traditional pattern matching. None of the cartridge cases were “matched” by either of these two experiments. Using these empirical findings, an established Bayesian probability model was used to estimate the chance that a 9‐mm cartridge case, fired from a GLOCK, could be mistaken as coming from the same firearm when in fact it did not (i.e., the random match probability).     

Homicidal Snake Bite in Children

Snake bites are common in many regions of the world. Snake envenomation is relatively uncommon in Egypt; such unfortunate events usually attract much publicity. Snake bite is almost only accidental, occurring in urban areas and desert. Few cases were reported to commit suicide by snake. Homicidal snake poisoning is so rare. It was known in ancient world by executing capital punishment by throwing the victim into a pit full of snakes. Another way was to ask the victim to put his hand inside a small basket harboring a deadly snake. Killing a victim by direct snake bite is so rare. There was one reported case where an old couple was killed by snake bite. Here is the first reported case of killing three children by snake bite. It appeared that the diagnosis of such cases is so difficult and depended mainly on the circumstantial evidences.     

Hesitation Wounds and Sharp Force Injuries in Forensic Pathology and Psychiatry: Multidisciplinary Review of the Literature and Study of Two Cases

The aim of this paper was to showcase the significant diagnostic value of hesitation wounds in terms of forensic, psychiatric, and medicolegal interest. A number of studies were reviewed to update and summarize the relevant literature on the incidence, distribution, character, and function of hesitation wounds as well as the sociodemographic variables and psychopathology of the inducers. This study also investigates their importance as a forensic criterion in the distinction between suicide and homicide as well as a psychiatric diagnostic tool in suicide prevention. In addition, the paper reports two new cases. Results conclude that there is equal incidence, but different distribution of hesitation wounds between genders. Furthermore, the low dispersion of hesitation wounds contrasts with the high dispersion of defense wounds. The inducers' psychopathology lies principally in Axis I disorders. Finally, there is a comprehensive analysis of non‐suicidal self‐injury and the role of self‐wounding in suicide prevention.

Pregnancy Loss,Skin-Based Body Modifications and Agency

This article utilizes notions of ‘agency’ to explore the relationship between experiences of pregnancy loss and narratives about related skin-based body modifications. The term ‘pregnancy loss’ is used to denote a range of medical events with potentially far-reaching emotional and social consequences. The research from which the empirical content of this article is drawn seeks to bring together feminist interests and the discipline of human geography to examine experiences of pregnancy loss. Different aspects regarding ‘agency’ are attended to through several practices—namely, the acquisition, display/concealment and narration of skin-based bodily marks like stretch marks and memorial tattoos. This includes a discussion on notions of ‘choice’ in terms of receiving/acquiring changes to the skin through pregnancy and pregnancy loss, regarding which stretch marks and tattoos are often pitted as oppositional. A more complex picture of agency is explored and illustrated with the narratives of several women with pregnancy-loss experiences, highlighting that both kinds of skin-based modifications can be framed in more agential ways, including as appreciated reminders of simultaneous love and loss. In doing so, this article constitutes an attempt to engage with pregnancy loss from a feminist perspective, as encouraged by Linda Layne, and to contribute to feminist scholarship on body modifications.

Molecular study of time dependent changes in DNA stability in soil buried skeletal residues

Stamp marks are used as a unique identification for a range of items, but these can be erased for criminal activities. Erased marks can sometimes be recovered by etching or magnetic means. The present study looked at the application of Fry's reagent to recover erased marks from steel. The investigation also demonstrated that Fry's reagent can deteriorate on storing and will require a longer etching time. The effect of different applied forces of stamping was investigated, and the depth of the underlying deformation was determined by etching after varying degrees of metal removal. The amount of metal needing to be removed depends on the force applied to the die. Metal removal also affects the time needed for recovery. The underlying structural change remains as a hidden identification mark, and could potentially be used by manufacturers as an unseen identifier. A model for the underlying deformation is proposed.     

The survival of oral streptococci on human skin and its implication in bite-mark investigation

Ten-microlitre aliquots of whole saliva applied to human skin were sampled for periods up to 6.25 h. The rate of loss of recoverable bacteria was 45–50% per hour. After 6.25 h, viable oral streptococci could be recovered. The implications for using a “fingerprint” typing method for these bacteria with regard to the identification of bite-marks are discussed.
