 Bloodstain Example - Expiration Pattern© 2008 FORident Software Inc. DescriptionThis example was generated by taking blood and mixing it with saliva in the mouth. The blood was then forced out by coughing. Any remaining blood was allowed to flow from the mouth and fall onto the target.
In the image there are several air bubbles, lighter coloured stains, and string-like stains that are not entirely linear. Note that when blood is mixed with saliva, it changes its physical characteristics. |
