Forensic Blood Pattern Analysis — An Important Tool In Forensics

At a suspected or known crime scene, there's often blood evidence found. Blood appears differently depending on the situation and the material on which it shows. Bloodstains could be challenging to examine on absorbent materials and may falsify. But trained blood pattern analysts use forensic science to investigate the blood evidence, amount of force used, and the causes of bloodshed. This article explains blood pattern analysis and its roles in forensic investigations.

Fundamentals of Blood Pattern Analysis  

A blood pattern analysis examines bloodstains at a crime scene to determine the cause of the bloodshed. That means, as the analyst, you interpret the opinions on what did or didn't happen by examining the shape, size, location, and distribution of bloodstain at the crime scene. However, the crime scene investigation (CSI) technicians make multiple measurements on the bloodstains at the crime scene and classify them for crime scene reconstruction. Therefore, a well-trained and qualified forensic analyst must analyze, characterize, and recognize different bloodstains patterns.

1. The Cast-Off Pattern 

The pattern is generated by blood drops unleashed from a blood-bearing object due to its motion. It indicates the direction the blood was moving when it hit the target surface. The general linear configuration categorizes it.

2. Drip Pattern 

The drip pattern is created when the blood droplets collide with another liquid to form a pattern that contains a parent stain.

3. Impact Pattern

 An impact pattern occurs when an object strikes a source of blood and can either be backward spatter or a forward spatter. It's the most common bloodstain pattern found at crime scenes. 

What Are the roles of Blood Pattern Analysis?

The primary role of blood pattern analysis includes:

1. It's a Powerful Tool for Solving Violent Crimes

Blood pattern analysis determines what comes off by providing important forensic information about the crime under investigation. Not only can analysts identify bloodstain at a crime scene, but they can also extract DNA evidence from the blood. That helps conclude the event of the crime, verify statements from the witnesses, and add or eliminate possible victims from the investigation. Generally, most analysts categorize the stains by collecting information from transfers, spatter patterns, voids, and other marks that helps investigate the series of event that happened after bloodshed.

2. Reconstruction of Crime Scene

Physical evidence and photographs from the crime scene are essential for a thorough reconstruction. Forensic blood pattern analysis determines the sequence of events that happened throughout and after the crime. It's done by studying, making clear patterns, and considering physical evidence at the scene.
