Violent crimes usually result in bloodshed. When physical forces act upon liquid blood, patterns will be deposited on the various items at the crime scene, as well as the clothing of the individuals present during the activity. These patterns can yield valuable information concerning the events that lead to their creation. The information can then be used for reconstruction of the incident, as well as to evaluate the statements of the witnesses and the crime participants. Bloodstain pattern evidence can be of value in the investigation of any violent crime in which bloodshed occurs.
