  Ante-mortem Wounds Definition: Ante-mortem wounds are injuries that occur while the individual is still alive. These wounds exhibit signs of physiological responses due to the body's reaction to injury. Characteristics : Signs of inflammation (redness, swelling) Presence of blood (hemorrhage) Healing processes may be observed (scabbing, blistering) Signs of pain or distress noted in the victim may be recorded Examples: Laceration: A cut caused by a sharp object, showing blood and possibly signs of infection or healing. Gunshot Wound: A penetrating injury from a firearm that results in bleeding and may show signs of trauma to surrounding tissues. Stab Wound: A deep puncture wound indicating an assault; would likely show tissue damage and swelling around it. Fracture: A broken bone due to impact, which would often result in significant pain and swelling. Post-mortem Wounds Definition: Post-mortem wounds are injuries inflicted on a body after death. These wounds do not exhibit the...

  Wounds can be broadly defined as a “disruption of the continuity of tissues produced by external mechanical force “.  Wounds which are present over the body to defend oneself from an assault are called defence wounds. In case of Death occurring from wounds the question is often raised as to whether they were the results of accident, suicide or homicide. In forensic science, distinguishing between suicidal, homicidal, and accidental wounds is crucial for homicide investigations, legal proceedings, and understanding the context of injuries. Each category has distinct characteristics, which forensic experts analyze to draw conclusions about the circumstances surrounding a death.  The opinion whether the death is caused by suicidal, homicidal or accidental wounds can be established by – 1. Circumstantial Evidence 2. Examination of crime scene 3. PM(post- mortem) Examination of Victim 4. Examination of Suspected person 5. Examination of Weapon The differences between Suicid...

A GLOBAL PERSPECTIVE Almost every country of the world has the provisions of scientific developments for the benefit and welfare of their citizens and nations. There are provisions contained in the constitutions across the world that talk about scientific research and developments.  The principle of criminal justice system is to protect the innocent from wrongly conviction and punishment of culprit. All this is possible only if the truth is searched by the investigating authorities. There is no doubt that constitutions of various countries speak about scientific advancements but when it come to applying scientific techniques in interrogation, across the globe, every nation hesitates. Worldwide, rights of accused persons are advocated. Doubts are raised regarding the capability and reliability of scientific techniques of investigation. The Universal Declaration of Human Rights, 1948 in Article 11.1 declares that accused is to be presumed innocent until proved guilty according to t...

WHAT IS BRAIN MAPPING? Brain Mapping is one more valuable scientific tool for investigation of crimes. Brain Mapping is also known as Late Positive Complex or P3 or P300.  It is a component of averaged brain potentials. In this test no questions are asked from the accused. He is made to sit in evoked potential recording machine and is shown objects relating to crime scene or is made to hear sounds pertaining to crime site. The sensors from his head pick the event related potentials in the form of Brain Mapping only if the person has been at the site of crime. Brain Mapping is a response of the brain to a stimulus which is shown to the subject.  HISTORICAL BACKGROUND In 1965, scientists were working on the research of Event Related Potentials and it was discovered by Sutton and his colleagues. It is very robust Event Related Potential.  As soon as it recognizes the stimuli it sends the reaction within 300 milliseconds of seeing the stimuli. If the person is attentive to th...

WHAT IS NARCO ANALYSIS Narcoanalysis has become an increasingly, perhaps most common term in India. It refers to the process of psychotherapy conducted on a subject by inducing a sleep like state with aid of drugs. A person is able to lie by using his imagination. In this test, the subject’s inhibitions are lowered down by interfering with his nervous system at the molecular level. In sleep-like state efforts are made to obtain “probative truth” about the crime as in sleep like state, it becomes difficult though not impossible for him to lie. It is believed that if a person is administered a drug which suppresses his reasoning power without affecting his memory and speech, he can be made to tell the truth.  Narcoanalysis is a form of psychotherapy and an effective aid to scientific interrogation. It is a process whereby a subject is put to sleep, or into a semi-somnolent state by means of chemical injections and then interrogated while in a dream like state. It is believed that if ...
