Methods for Distinguishing Between Postmortem and Perimortem Trauma Prepared by - Naman Devnani, Bachelor’s in Computer Applications - BAOU , v olunteer of C.A.S.E. 23 Official Understanding the timing of injuries is critical in forensic investigations. Two key concepts a re postmortem trauma, which occurs after death, and perimortem trauma, which happens a round the time of death, either just before or just after. Distinguishing between these two can h elp determine the cause and circumstances of death. 1. Wound Appearance Perimortem Trauma - Injuries inflicted during the perimortem period often show signs of blood circulation. This means there might be bruising, bleeding, or swelling around the wound because the heart was still pumping blood when the injury occurred. Bones fractured perimortem can display sharp edges and lack healing signs. Postmortem Trauma - Injuries after death usually lack these signs because blood is no longer circulating. Bruising, if present, will be minimal o

Lacerations: What you need to know!  Author: MOUNASHREE AM, M Sc Forensic Science, Yenepoya Institute of  ASCM A laceration is a type of mechanical damage. It is due to a blunt force impact that tears or splits tissue. MECHANISM Upon collision, the tissue is compressed and stretched above the elastic limit, resulting in a rip in the skin. Unlike incised wounds, there is a break in the continuity of the tissue caused by tearing. CHARACTERISTICS The continuity of the tissue is interrupted because of tearing. The wound has three dimensions - length, breadth, and depth. Margins are uneven and ragged. There could be bruising or crushing of the edges, usually in a small area. The depth of the wounds can reveal the underlying blood vessels, nerves, and fragile tissue bridges. Tiny, shallow tails at the end of the cuts stem from the main cut are noticed. The amount of bleeding from laceration wounds is less compared to incised wounds. The shape and size of the injury may not match the tool or

ENVIRONMENTAL FORENSICS                                                                               Author: Charan Tej Rayapu, 3rd Year B.Sc., Microbiology, Biotechnology & Biochemistry, SVKP & Dr.K.S.Raju Arts and Science College, Penugonda. DEFINITION: Environmental forensics is the systematic and scientific evaluation of physical, chemical, and historical information to develop defensible scientific and legal conclusions regarding the source or age of contaminant released into the environment. It involves the application of principles from various fields such as chemistry, biology, geology, and environmental science to solve ecological problems. Environmental forensics can be used to investigate various environmental issues, including contaminated sites, air pollution, water pollution, and water disposal. TECHNIQUES OF ENVIRONMENTAL FORENSICS: The main application of environmental forensics techniques is basically for contaminant age dating & source identification. Whi
