Crime scene – location where an illegal act took place, and comprises the area from which most of the physical evidence is retrieved by trained law enforcement personnel, crime scene investigators (CSIs) or in rare circumstances, forensic scientists. Mortuary investigations; laboratory examinations
Forensic profiling is generally conducted using datamining technology, as a means by which relevant patterns are discovered, and profiles are generated from large quantities of data. [ 1 ] A distinction of forms of profiles that are used in a given context is necessary before evaluating applications of data mining techniques for forensic profiling.
Crime scene reconstruction help put pieces of a case together. The steps to crime scene reconstruction involve: the initial walk-through and examination of the crime scene, organizing an approach for collecting evidence, formulate a theory, use the theory to track down suspects, reconciling all evidence that refutes the hypothesis or creates one.

The FBI’s database used for DNA is CODIS, Combined DNA Index System. It has data at three levels: local, state, and national. The national level data is stored in NDIS, National DNA Index system.
Bloodstain pattern analysis is the scientific examination of blood spatter patterns found at a crime scene to reconstruct the events of the crime. Comparative forensics is the application of visual comparison techniques to verify similarity of physical evidence. This includes fingerprint analysis, toolmark analysis, and ballistic analysis.
After the trace evidence has been located at a crime scene the next step is to record it. [5] There are multiple ways of recording evidence and that is dependant on the type of evidence found. The first option is to videotape the crime scene. This can be done to provide perspective on the actual location of the evidence throughout the entire ...
Bloodstain pattern analysis (BPA) is a forensic discipline focused on analyzing bloodstains left at known, or suspected crime scenes through visual pattern recognition and physics-based assessments. This is done with the purpose of drawing inferences about the nature, timing and other details of the crime. [ 1 ]
With the use of crime scene photography, the context of the crime scene can be represented through a series of photographs, aiming to tell the whole story. [5] Such photographs are used to capture the physical environment of the scene and its surroundings, in addition to physical evidence in situ and key areas of the crime scene (e.g ...
