Which bloodstain pattern could indicate the sequence of events?

Impact and projected spatter stains are particularly informative when it comes to determining the sequence of events in a crime scene. These types of bloodstains are created when blood is forced away from the source, often resulting from blunt force trauma or gunshots. The size, shape, and distribution of the spatter can provide insights into the dynamics of the incident, including the position of the victim and the assailant, the type of weapon used, and the direction of force applied.

For instance, smaller spatter patterns often indicate a closer range of impact, while larger splatters can suggest a more forceful action from a distance. Additionally, the presence of a specific pattern can help reconstruct the sequence in which the events unfolded. For example, if one area has a dense concentration of blood spatter, it may indicate the point of impact or a particular struggle, allowing investigators to piece together the narrative of the incident.

In contrast, transfer stains consist of blood being transferred from one surface to another, typically revealing contact events but lacking detailed information about the dynamics of those events. Splash patterns indicate more passive movements of blood and do not provide as much information about timing or the sequence of violence. Skeletonized stains may indicate that blood has dried in a pattern
