ABSTRACT
Crime Scene Investigation provides the backbone for criminal investigation and serves as the bedrock for carrying out justice. The reliability of police evidence gathered at a crime scene influences what can be confirmed in forensic analysis and the strength of prosecution in a criminal trial. The integrity of a crime scene is likely to be destroyed when there is evidence contamination during the course of a crime; when it is changed or destroyed. Crime scene contamination can be caused by mishandling of evidence, failing to secure the scene of a crime, environmental exposure, or by negligence by first responders or investigators. Such contamination can severely influence the evidentiary value of forensic material and cause erroneous forensic interpretation. Forensic science has become an important tool for establishing the accuracy of crime and connecting the crime scene to the perpetrators in the modern legal system.
Methods like DNA profiling, fingerprint analysis, bloodstain patterns and trace evidence need the maintenance of the evidence at the scene of criminal activity. And as such, when contamination occurs, such scientific techniques can yield false or unreliable findings. As such, tainted evidence might corrupt a case for prosecution, result in false convictions, or be used to exonerate criminals, all of which can discredit the criminal justice process. In India, although substantial usage of forensic science services (and a string of recent amendments to criminal procedure laws) are on the rise, numerous structural and procedural problems remain that remain obstacles to managing crime scenes effectively. These problems encompass the insufficient forensic equipment, lack of training of police officers, lack of uniform procedures regarding handling evidence and delays in forensic process. Consequently, crime scene contamination continues to be a big problem in criminal inquiries and the outcome of any court cases. This article explores the term, causes of contaminated crime scenes and its wider implications for Indian criminal justice management. It concludes that due to insufficient evidence under present Indian criminal laws there remain problems arising in forensic evidence collection - and also it argues for better procedures concerning investigation, changes in policy processes.
