## What is the area of convergence and how does it help an investigator?

The area of convergence is the point on a two-dimensional plane from which the drops orig- inated. It tells the investigator approximately where the source of blood (the victim) was located at the time of impact.

## What information can an investigator gain from the location of the area of origin?

What information can an investigator gain from the location of the area of origin of a bloodstain pattern? Position of the person form which the pattern originated.

What is the point of convergence in forensics?

Point (Area) of Convergence — The common point (area), on a two dimensional surface, over which the directionality of several blood drops can be retraced. Point (Area) of Origin — The common point (area) in a three dimensional space to which the trajectories of several blood drops can be retraced.

Why is the area of convergence used?

To help reconstruct events that caused bloodshed, analysts use the direction and angle of the spatter to establish the areas of convergence (the starting point of the bloodshed) and origin (the estimation of where the victim and suspect were in relation to each other when bloodshed occurred).

### What does the area of convergence tell investigators?

Area of Convergence – The area containing the intersections generated by lines drawn through the long axes of individual stains that indicates in two dimensions the location of the blood source.

### What is the difference between the point of convergence and the point of origin?

The source of blood spatter can be localized by following the direction of travel of several stains. What is the difference between the point of origin and point of convergence? Point of origin is in 3D space, point of convergence is in 2D space. Passive – no force applied to blood other than gravity.

What is the difference between area of convergence and area of origin?

Area of Convergence – The area containing the intersections generated by lines drawn through the long axes of individual stains that indicates in two dimensions the location of the blood source. Area of Origin – The three-dimensional location from which blood spatter originated.

What information can void patterns give?

A void occurs when a person or object blocks the path of the blood. They are important because voids can show investigators if objects are missing from the scene, where a person or persons were at the time of the incident, and if a body was moved.

#### What is the point of convergence?

3. The point of converging; a meeting place: a town at the convergence of two rivers. 4. Physiology The coordinated turning of the eyes inward to focus on an object at close range.

#### What is the difference between the area of convergence and the point of origin?

What does the area of convergence tell you?

Area of Convergence. If you have a number of bloodstains, the area of convergence can be determined by drawing lines from the leading edge of stains through the long axis. The lines come together in a general area where the blood has emerged, helping to locate the origin of the bloodstains.
