Forensic Geology: Unveiling Crime Through Earth’s Clues

Image
  By Alina prem (Garden city university, Msc Forensic science graduate, Bengaluru). Forensic geology is the important interdisciplinary science that incorporates the geological sciences into criminal investigations. Materials such as soil, rocks, and minerals, when analyzed by forensic geologists, provide critical evidence necessary to help in associating suspects with crime scenes, solutions of environmental crimes, and even in the identification of victims. Applications in Criminal Investigations: Forensic geology makes crucial contributions to criminal cases involving homicide, burglary, and environmental offenses. For instance, soil examination perhaps may indicate special geologic markers that would serve to positively identify a suspect as having been at a crime scene. This is based upon the "Locard Exchange Principle" that simply states that whenever two objects come into contact, materials will be exchanged between them. It has been used in high-profile cases, such ...

Postmortem Redistribution

Image
  By Vaishali Rajoriya(Volunteer at C.A.S.E. 23) A critical concept in forensic toxicology, which refers to changes in the concentration of substances in the body following death, is postmortem redistribution. This phenomenon can significantly impact the interpretation of toxicological analyses and forensic investigations. Understanding the mechanisms and implications of postmortem redistribution is essential for accurate death investigations and legal outcomes. Mechanisms of Redistribution Postmortem redistribution occurs due to the cessation of circulatory and metabolic processes, which leads to the redistribution of substances within the body. After death, the lack of blood circulation causes the concentration of drugs and toxins in various tissues to become uneven. Several factors contribute to this redistribution: 1. Diffusion : After death, the equilibrium between blood and tissues starts to shift. Substances that were previously distributed in the bloodstream begin to diffus...

Image
  By: Prajwal Biswas M. Sc. in Forensic Science, National Forensic Sciences University Volunteer of C. A. S. E. 23. Introduction: FDP (Forensic DNA Phenotyping) is an emerging technology that relies on genetic information to predict physical properties ranging from skin color and hair color to eye color and even the structure of the facial form. It supports criminal investigations, where it allows researchers to produce a visual profile of an unknown suspect based solely on DNA samples. At the same time as it promises to crack especially those most difficult cases, especially cold cases, this technology raises a number of ethical dilemmas that must be solved in order to balance public safety with individual privacy.           Figure 1 Forensic DNA Phenotyping Privacy Matters: One of the most fundamental ethical issues has to do with privacy. Even though FDP screens for genes that determine physical characteristics, DNA contains a lot more sensitive informat...

NARCO ANALYSIS: LISTENING TO THE TRUTH

Image
  By: Karuna Ajith Kini, 1st Year M.Sc Forensic Science, Kasturba Medical College, Mangalore Introduction   The term ‘narco-analysis’, coined by Horsley is derived from the Greek word nark meaning anesthesia. It is a diagnostic and psychotherapeutic technique that uses psychotropic drugs like barbiturates to induce a stupor in which the mental elements come to the surface that can later be used by the investigator. The Indian Evidence Act remains silent on narco analysis but critics argue that it goes against the fundamental right granted by the constitution to right against self-incrimination. Testing: In India, the narco-analysis test is done by a team comprising an anesthesiologist, a psychiatrist, a clinical/ forensic psychologist, an audio-videographer, and supporting nursing staff. The test is conducted by mixing 3 grams of Sodium Pentothal or Sodium Amytal or Seconal or Hyoscine (scopolamine) and dissolving it in 3000 ml of distilled water. The chemical substance is a b...

POSTMORTEM CHANGES: A THANATOLOGICAL PERSPECTIVE.

Image
 Author: AISWARYA S, BSc. (Hons) FORENSIC SCIENCE Yenepoya University, Mangalore, Karnataka. Thanatology is a branch of science that deals with the scientific study of death. "The basic concept is that death is the irreversible loss of the capacity for consciousness and capacity to breathe". A body undergoes complex changes after death. Postmortem changes depend on numerous factors such as temperature, season, geographical location at which the body is found etc. Postmortem changes are being described under the following headings: 1. IMMEDIATE CHANGES: which result in irreversible cessation of functions of the brain, heart, and lungs. Muscles of the body become flaccid, and corneal reflexes are abolished. 2. EARLY CHANGES: which take place between the first 12 to 24 hours. They comprise: Changes in the skin: Elasticity disappears quickly after death. Skin that was translucent in life becomes pale. Changes in the eye: The cornea loses its luster with the passage of time. It be...

  Firearms and Neuroscience: A Glimpse into the Shooter's Mind. - By Saanvi Soni (Volunteer at C.A.S.E. 23 OFFICIAL) Firearm use and diagnostic methods intersect in terms of the investigation of psychological and neuropsychological aspects underlying the shooting behavior. Evolving this question within the scope of the shooter's mind, justice has to understand to what extent stress, adrenaline, and cognitive activities determine the making of decisions and performance in functional actions under pressure. Due to the development of neuroscience, it has been to some extent conceptualized how an individual respond to threats, evaluates risks, and how training can alter performance. Such integrated methods clarify not only how shooting is executed, but also how feelings, thoughts and behaviors interact, contributing to the understanding of single acts with firearms more in depth as well as their uses in society. Interestingly, not everybody who undergoes such triggers becomes a sh...
