What can blood spatter patterns indicate?

Blood spatter patterns provide valuable information about the dynamics of a violent incident, particularly the relative positions of the victim and assailant at the time of the attack. By analyzing the direction, shape, and distribution of blood droplets, investigators can reconstruct the scene of the crime. For instance, the angle at which the blood strikes a surface can reveal the position of the victim and how the assailant moved in relation to them. This is foundational in crime scene reconstruction, as it helps paint a clearer picture of what transpired during the assault.

Other options may address different aspects of a crime investigation, but they do not directly relate to the primary purpose of blood spatter analysis in determining spatial relationships during the event.
