How Forensic Evidence Helps Solve Crimes

Abstract

Abstract

Forensic science plays a significant role in modern criminal investigations by applying scientific methods to the identification, collection, preservation and analysis of evidence. Forensic evidence assists investigating agencies in reconstructing crime scenes, identifying suspects, establishing connections between individuals and criminal activities, and presenting scientific findings before courts of law. Evidence such as DNA profiles, fingerprints, bloodstain patterns and digital records can contribute to the investigation and prosecution of criminal offences. However, the reliability of forensic evidence depends on proper collection procedures, preservation of evidentiary integrity, scientifically valid examination techniques and impartial interpretation of results. Contamination, inadequate laboratory facilities, incorrect interpretation and weaknesses in maintaining the chain of custody may affect the evidentiary value of forensic findings. In India, forensic evidence must also be evaluated within the framework of applicable criminal procedure and evidence law, particularly the Bharatiya Sakshya Adhiniyam, 2023. This article examines the importance of forensic evidence in criminal investigations, its major forms, its evidentiary value, and the legal and practical challenges associated with its use. It argues that forensic science can strengthen the administration of criminal justice when supported by scientific reliability, procedural safeguards, expert accountability and judicial scrutiny.
