Which aspect is not usually assessed in bloodstain pattern analysis?

In bloodstain pattern analysis, various aspects are examined to reconstruct the events surrounding a violent incident. The analysis focuses on physical evidence related to the bloodstains themselves, which can reveal significant information about the actions that occurred during the incident.

Assessing the movement after bloodshed involves looking at the distribution and arrangement of bloodstains to infer how the individuals involved moved through the area after the blood was shed. This can provide crucial insights into the sequence of events.

The positioning of the victim is also assessed, as the location and angle of bloodstains can indicate where the victim was at the time of the incident. Understanding the position aids in piecing together the narrative of how the violence unfolded.

Determining the area of origin of the blood is fundamental in bloodstain pattern analysis. It helps investigators establish where the blood was initially deposited, which is critical for reconstructing the scene.

In stark contrast, the financial motive of the suspect falls outside the realm of scientific examination of the physical evidence. While motives can influence investigations and provide context, they are not assessed through bloodstain patterns themselves, making this aspect irrelevant to the analysis of bloodstains. Thus, the financial motive is not a parameter considered in the scientific analysis process.
