Question 1
When analyzing the blood droplet or bloodstain, the presence of scallops, spatter, tails or spine usually assist the analyst to identify the path that the droplet was travelling in at impact. Unless the impact of the droplet was at 90o, the axis that is associated with the travel direction of the droplet tends to be longer due to droplets skimming action on the target. For example, at an impact of 90o, smaller scallops tend to appear around the stain’s entire periphery. When the impact is 70o, larger scallops tend to be more concentrated on one side of this Continue reading...
