Bloodstains are an important piece of evidence offering clues to the nature of the accident or crime. Moreover, detailed analysis of the blood obtained from a stain can reveal genetic and other information that can help identify a victim or implicate the person responsible.
Analysis of bloodstains can also help reveal the nature of the injury, the order in which the wounds were received, the weapon used to inflict the injury and whether or not the victim was moving or motionless when injured. When dealing with a bloodstain, a forensic investigator will seek to obtain as much information as possible without disturbing the scene.
