Abstract: The location of any evidence in a crime scene is of vital importance and so, is the location of blood in a crime scene. In this research investigation, identification of the location co-ordinates of blood is performed in simulated crime scene using DGPS. DGPS co-ordinates of all evidences were taken using DGPS receiver and the distance of blood source and blood stain is computed using Co-ordinate Distance Calculator. The baseline measurements of the scene along with other evidence was also carried out. Further, the computed data was compared to manual measurement to find the difference between the measurements using the two methods. The results indicate that the mean difference between the computed distance using DGPS co-ordinates with Co-ordinate Distance Calculator and manual measurement is 1.6, 1.93, 4.4, 1.95, 2.4, 1.6, 0.33 and 3.95 for 8 crime scenes. The average of the calculated mean difference of all eight scenes were calculated as 2.27 feet. Thus, DGPS can be used in crime scene management for collection of location with co-ordinates of evidence, like hair,fiber,saliva, blood stain etc. which was helpful in crime scene reconstruction.
