          Bloodstains are one of the most crucial forms of evidence in a fo-

          rensic examination. Examining the pattern and quantity of blood

          found at a crime scene could provide details on the nature of the

          crime. Its in-depth analysis can reveal absolute pieces of informa-

          tion such as the identification of a victim or the culprit responsible
          for the crime, the nature of the injury, the weapon used to inflict the

          injury, etc.

                 When entering a scene of the crime, the investigating officer

          must be able to detect and record their findings by means of sketch-

          ing, video, and photographing evidence. For evidence pertaining to

          bloodstains, the application of luminol and other blood detection

          techniques can be employed. Luminol is a widely used chemical for
          the detection of blood stains at a scene of crime. It basically reacts

          with the iron components of the blood and fluoresces when viewed

          in the dark. Apart from the dramatic flair it provides, it is accom-

          panied by a few setbacks. The technique improvised to counter the

          setbacks of luminol tests is ‘Steam Thermography’.
