Crime Scene

Crime scene investigation varies from case to case, as well as the type and scope. Local agencies' circumstances apply different procedures. One of the main responsibilities is to preserve physical evidence, collect and submit the evidence for scientific examination.

Physical evidence plays a potentially critical role in the overall investigation and resolution of a suspected criminal act. Documented and preserved evidence is not easier with the development of technology. Investigators have to follow an objective, thorough, and thoughtful approach to presume the legal significance of the scientific evidence.
