Forensic Evidence and Crime Scene Investigation

Contemporary law enforcement has greatly expanded its ability to solve crimes by the adoption of forensic techniques and procedures [1]. Today, crimes often can be solved by detailed examination of the crime scene and analysis of forensic evidence [2]. The work of forensic scientists is not only crucial in criminal investigations and prosecutions, but is also vital in civil litigations, major man-made and natural disasters, and the investigation of global crimes. The success of the analysis of the forensic evidence is based upon a system that emphasizes teamwork, advanced investigative skills and tools (such as GPS positioning, cell phone tracking, video image analysis, artificial intelligence and data mining), and the ability to process a crime scene properly by recognizing, collecting and preserving all relevant physical evidence [3].
