Indian forensic researchers unveil breakthroughs in post-mortem science at IAFS

Two forensic researchers from India recently presented groundbreaking studies at the International Association of Forensic Sciences (IAFS) in Sofia, Bulgaria. Their work covers post-mortem investigations, hormonal changes in suicidal deaths, and advanced techniques for determining cause of death. Dr Raghvendra Kumar Vidua led research on post-mortem sperm retrieval in cases of hanging-induced asphyxia. His findings suggest that sperm can often be successfully extracted within 24 hours of death. This is due to the abrupt cerebral hypoxia caused by hanging, which limits wider cellular damage.

Dr Vidua also explored other forensic topics, including the use of an innovative sample dryer for effective drying in investigations. His work extended to forensic radiology and imaging applications in medicolegal cases across India. Meanwhile, Dr Abarnna Sree SB focused on histopathological changes in the pineal, pituitary, and adrenal glands of suicide victims. The study included hormonal and psychological assessments to better understand the biological factors involved. Aswini Chandran, a PhD research scholar, contributed research on integrating post-mortem microbiology with biomarker technology. The aim is to improve the accuracy and reliability of determining cause of death in forensic cases.

The studies presented at IAFS highlight advances in forensic science, from post-mortem retrieval techniques to hormonal analysis in suicides. These findings could refine investigative methods and provide clearer insights in medicolegal examinations.
