Abstract

This research emphasizes how the application of materials engineering in forensic investigation. Forensic science is the application of science to law enforcement and civil laws are enforced by the police force in criminal justice system. Criminalistics or crime laboratory is concerned with the recognition, identification, individualization and evaluation of physical evidence using the methods of the natural sciences in matters of legal significance. Materials science and engineering is a realization concerning every application of materials, which all are related with the properties of materials. Forensic scientist can be applied in materials science and engineering knowledge and methodology to solve legal problems and criminal investigations. In order to improve the statistics of solving the criminal and legal cases, materials engineering play an important role helping forensic scientist to collect, identify and analyse the evidence and link the suspects with the crime scene or victim. Sometimes, when forensic scientist failed to identify and analyse the evidence, materials science and engineering knowledge are crucial to investigate the theory behind the failure. Again, all the evidence at crime scene is carrying useful and important information. Thus, forensic scientist must have a better understanding of the materials properties and able to apply the right method to avoid destroying or tampering every piece of the evidence.
