Key Terms… For each of the key terms, roll over the term to see the definition.
the term that matches each definition below: (Terms are not in the same order as the
key terms in the lesson.)
A drop of blood from which a wave, cast-off, or satellite spatter
That blood which has been dispersed as a result of force applied
to a source of blood. Patterns produced are often characteristic of
the nature of the forces which created them
Angle of impact
The acute angle formed between the direction of a blood drop and
the plane of the surface it strikes.
Projected Blood Spatter
A bloodstain pattern that is produced by blood released under
pressure as opposed to an impact, such as arterial spurting.
The common point (area) in a three dimensional space to which
the trajectories of several blood drops can be retraced.
Passive Blood Stains
Evidence that liquid blood has come into contact with a surface.
Bloodstain drop(s) created or formed by the force of gravity
acting on an injured body.
The pointed or elongated stains which radiate away from the
central area of a bloodstain
Contact/Transfer blood stains
A bloodstain pattern created when a wet, bloody surface comes in
contact with a second surface. A recognizable image of all or
portion of the original surface may be observed in the pattern.
Results from objects coming in contact with existing bloodstains
and leaving wipes, swipes, or pattern transfers behind such as a
