Blood Spatter Analysis

Front

A blood stain increases in diameter as the height of origin ________________.

Back

increases

Front

What is the term for the point where blood stains converge?

Back

Convergence point

Front

What angle is most likely associated with a blood drop that falls straight down?

Back

90°

Front

Which direction would blood drops travel if a person is running to the right?

Back

The drops would show a pattern indicating movement to the right.

Front

What does the diameter of a blood stain indicate about the height from which it fell?

Back

A larger diameter indicates a greater height of origin.

Front

What is the significance of the angle of impact in blood spatter analysis?

Back

The angle of impact helps determine the direction from which the blood originated.

Front

How can you determine the height of origin from blood spatter?

Back

By measuring the diameter of the blood stain and applying the appropriate formulas.

Front

What is the relationship between the angle of impact and the shape of the blood stain?

Back

A more acute angle results in a more elongated stain, while a 90° angle results in a circular stain.

Front

What does a blood stain pattern indicate about the movement of a victim or suspect?

Back

It can indicate the direction of movement and the position of the person at the time of the bloodshed.

Front

What is the formula to calculate the height of origin based on the diameter of a blood stain?

Back

Height = (Diameter^2) / (8 * sin^2(angle of impact))
