Beware of using a white ruler or measuring tape in close-up pictures. The meter may take the light reading of the scale and the skin tones and injury will be too dark. This can be avoided by keeping the scales at the edge of the photo since most light meters are center weighted. The crime victim should be accompanied by a Victim's Assistant from the District Attorney's office when being transported to the laboratory. A short interview is conducted to determine the location of the injuries and how the injuries occurred.
Bruises are transfer patterns.
The victim's statements may be supported by placing fingers on the finger marks or blunt instruments over blunt injury bruises. If a weapon was used, be sure to bring it to the photos session whenever possible. Rough anatomical drawings and a standardized form are used to determine the time interval for each injury. Any scars or birthmarks are also noted. Also identify the victim and include a case number for reference.
