Blood Spatter

What blood spatter pattern is seen in the picture?

• Transfer/Contact

• Swipe

• Wipe

• Saturation

Based upon this picture, what test was done to determine whether or not a stain was blood (the picture shows a positive and negative test).

• Kastle-Meyer presumptive blood test

• Leukomalachite green presumptive blood test

• Luminol presumptive blood test

What type of spatter creates the largest blood droplets?

• Low velocity impact

• Medium velocity impact

• High velocity impact

What type of blood-spatter creates the smallest blood drops?

• Low velocity impact

• Medium velocity impact

• High velocity impact

What blood spatter pattern is seen in the photo?

• Low Velocity

• Expirated Blood

• High Velocity

• Medium Velocity

A blood spatter analyst conducted an experiment to see if the height at which blood drops affect the diameter of the blood spatters. Below is a graph of their data with a line of best fit to show the trend.

The next week the analyst was called into a crime scene where there were passive blood spatters that averaged 20 mm in diameter. The analyst used their experimental data to determine the blood likely fell from a height of ________________. 

• 160 cm 

• 160 mm 

• 13 mm 

• 180 cm 

• 13 cm
