Blood spatter refers to the pattern of blood droplets, stains, or pools that result from a violent event, such as a homicide or assault. Analyzing these patterns can provide crucial information about the circumstances surrounding the incident, including the type of weapon used, the position of the victim, and the sequence of events. Forensic experts study blood spatter to determine the direction and force of the blood's movement. Different patterns, such as arterial spray or cast-off, can indicate specific actions during the event. This analysis plays a vital role in criminal investigations and can help establish timelines and clarify witness statements.
