Bloodstain Pattern Analysis seeks to define the facts surrounding some violent incident in question. The examination of the physical nature of bloodstains provides information specific to the events that occurred during the incident.
We often refer to what the analyst evaluates as the static aftermath of an event. Dispersion, shape characteristics, volume, pattern, the number of bloodstains, and their relationship to the surrounding scene are part of this aftermath. This information provides the investigator with a window to the past. Often the analyst finds direct and convincing information that makes the role of the fact finder much easier.
The information we are likely to discover through an examination of the bloodstains includes:
|
|
- The direction a given droplet was traveling at the time of impact
|
|
|
|
- The probable distance from the target from which the droplet originated
|
|
- The nature of the force involved in the bloodshed and the direction from which that force was applied.
|
|
- The nature of any object used in applying the force
|
|
- The approximate number of blows struck during an incident
|
|
|
- The relative position in the scene of the suspect, victim, or other related objects during the incident
|
|
|
- Sequencing of multiple events associated with an incident
|
|
|
- In some instances, which hand delivered the blows from a beating
| |
| In essence, the analyst seeks to identify ?what happened? during the bloodshed that would produce the bloodstains as they are found at the scene, on the victim, the suspect or their clothing. |
