Blood Evidence Angle of Impact

Small secondary droplets around the main blood spatter drop are called:

• Spikes
• Splats
• Satellites
• Gushes

The drop shown above would have more than likely been dropped from an angle of 

• 90
• 50
• 30
• 10

The drop shown above would have more than likely been dropped from an angle of around

• 90
• 50
• 30
• 10

What blood spatter pattern is seen in the picture?

• Transfer/Contact
• Swipe
• Wipe
• Saturation

The protrusions around and connected to the drops are called

• radial lines
• spines or spikes
• blood edges
• satellite spatters

Given blood spatter patterns, it is possible to determine the direction the blood was traveling, the angle of impact, and the point _________________________________________.

• impact

• trajectory

• of origin of the blood

• None of the above

What happens to the shape of a blood droplet as the angle of release changes from a 90-degree drop toward a 10-degree drop?

• It becomes more wider than long

• It becomes more circular

• It has more spines

• It becomes more longer than wide

Which one of these was dropped from the biggest angle?

• 1 (top left)
• 4 (top right)
• 7 (bottom left)
• 9 (bottom right)

The lines in the picture are illustrate the points/lines of ___.

• convergence

• agreement

• tangents

• credit

As the height of a vertical drop increases we would expect to see

• The diameter increase and fewer spines and satellites

• The diameter decrease and fewer spines and satellites

• The diameter increase and more spines and satellites

• The diameter decrease and more spines and satellites
