ch 8 Forensics Blood & Blood Spatter

Front

What can be determined by blood spatter pattern analysis?

Back

Direction of origin, Angle of origin, Area of origin, General velocity, All of the above.

Front

What does a 'walking drip' blood spatter pattern indicate?

Back

It indicates a pattern created by blood dripping from a moving source.

Front

What is a Transfer/Contact blood spatter pattern?

Back

A pattern created when a blood-bearing object comes into contact with a surface.

Front

From what angle is a blood drop most likely dropped if it appears circular?

Back

90 degrees.

Front

What is a Cast-Off Pattern?

Back

A bloodstain pattern created when blood is flung from a blood-bearing object in motion onto a surface.

Front

What does the term 'medium velocity impact' refer to in blood spatter analysis?

Back

It refers to blood spatter resulting from a forceful impact, typically producing droplets of varying sizes.

Front

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

Back

It helps determine the direction from which the blood originated.

Front

What is the difference between 'wipe' and 'swipe' patterns in blood spatter?

Back

A 'wipe' pattern is created when an object moves through wet blood, while a 'swipe' pattern is created when a blood-bearing object moves across a surface.

Front

What does the presence of bubbles in blood droplets indicate?

Back

It indicates that the blood has been expelled from the nose or mouth due to an internal injury.

Front

How can the area of origin be determined in blood spatter analysis?

Back

By analyzing the angles and distances of blood droplets from a central point.
