what is an example of a scenario where you would see combination spatter? - Answer
victim is stabbed in chest or neck - see impact spatter from force of attack and
projection spatter from arterial bleeding, expirated, or cast-off blood
classification by velocity looks at not only the velocity at which the impacting object
strikes the blood source but also... - Answer the velocity at which blood leaves the blood
source when struck
classification by velocity divides into what different categories? - Answer low, medium,
and high velocity
the different velocity categories give an indication of what? - Answer the object and
mechanism used to make the spatter
this type of spatter occurs when an object traveling less than 5 ft/second strikes a
surface - Answer low velocity spatter
what would the spatter typically look like/size in low velocity spatter? - Answer fairly
large spatter - greater than 4mm
low velocity spatter is produce by what type of mechanisms? - Answer drops dripping
from wound or blood-soaked clothing or weapons
an arterial bleed would produce what type of pattern? - Answer freely spurting artery
results in linear and cascading spatter pattern
, as the victim loses blood with an arterial bleed, what will happen to the pattern? -
Answer pattern's distance from wound, length, and volume may decline steadily as
victim loses blood volume and pressure
this type of spatter occurs from objects moving between 5 and 100ft/second - Answer
medium velocity spatter
what sizes are medium velocity spatter typically? - Answer smaller than low velocity (1-
4mm)
medium velocity spatter is created by what mechanisms? - Answer impacts with blunt
or sharp objects and possibly expirated blood
spatter from this type of object distributes blood in all directions from area of impact -
Answer blunt objects
this type of spatter results from an object striking victim at speed faster than
100ft/second or from expirated blood - Answer high velocity
average size of high velocity spatter - Answer less than 1mm - mist like stains
most high velocity spatter is associated with this type of mechanism - Answer gunshots -
appearing near entrance and exit wounds
*w/ gunshot wounds, fine spatters behave differently depending on whether bullet is
entering or exiting body
transfer pattern - Answer blood stain pattern resulting from when an object soaked in
blood comes in contact with unstained object
