Term | Definition |
Angle of Impact | the acute angle formed between the direction of a blood drop and the plane of the surface it strikes |
Arterial Spurting | blood pattern(s) resulting from blood exiting the body of under pressure from a breached artery |
Back Sputter | blood directed back toward the source of energy or force that caused the spatter |
Blood Spatter Analysis | field of forensic science that deals with physical properties of blood and the patterns produces under different conditions as a result of various forces applied to the source of blood |
Bloodstain | evidence that liquid blood has come into contact with a surface |
Cast Off Pattern | a bloodstain pattern created when blood is thrown from a moving blood bearing object |
Contact Stain | blood deposited from direct contact between two surfaces, at least one of which is blood |
Direction of Flight | the trajectory of a blood drop, which can be established by its angle of impact and directionality angle |
Directionality | the direction the blood was traveling when it hit the target surface; established from the geometric shape of a bloodstain |
Directionality Angle | the angle between the long axis of a bloodstain and a predetermined line on the plane of the target surface that represents 0 degrees |
Draw-back Effect | blood in the barrel of a firearm that has been drawn backward into the muzzle |
Drip Pattern | a bloodstain pattern that results from blood dripping into blood |
Expirated Blood | blood that is blown out of the nose, mouth, or a wound as a result of air pressure or air flow, which is the propelling force |
Flight Path | the path of the blood drop as it travels through space from the impact site to the target |
Flow Pattern | a change in the shape and direction of a bloodstain due to the influence of gravity or movement of the object |
Forward Spatter | blood that travels in the same direction as the source of energy or force that cause the spatter |
High-Velocity Impact Spatter(HVIS) | bloodstain pattern caused by a high speed impact or force to a blood source, such as that produced by gunshot |
Impact Pattern | bloodstain pattern created when blood receives a blow or force resulting in the random dispersion of smaller drops of blood |
Impact Site | the point where meets a blood source |
Low-Velocity Impact Spatter(LVIS) | a bloodstain pattern caused by a low-speed impact or force to a blood |
Medium-Velocity Impact Spatter(MVIS) | a bloodstain pattern caused by a medium-speed impact or force to a blood source; a beating or stabbing type of spatter |
Misting | blood that has been reduced to a fine spray as a result of the energy or force applied to it |
Parent Drop | a drop of blood that casts off a wave or satellite spatter |
Passive Drop | bloodstain drop(s) created or formed by the force of gravity alone |
Area of Origin | the common area of a 3-D space to which the trajectories of several blood drops can be retraced |
Area of Convergence | the common area on a 2-D surface, over which the directionality of several blood drops can be retracted |
Projected Blood Pattern | a bloodstain pattern produced by blood released under pressure, such as arterial spurting, as opposed to by an impact |
Satellite Spatter | small droplets of blood distributed around a drop or pool of blood as a result of the blood hitting the target surface |
Spatter | blood that has been dispersed as a result of force applied to its source; a spatter pattern will vary depending on the force that created it |
Spine | the pointed or elongated stains that radiate from the central area of a bloodstain |
Swipe Pattern | the transfer of blood from a moving surface onto an unstained surface; direction is determined by the feathered edge |
Target | surface on which blood has been deposited |
Transfer or Contact Pattern | bloodstain pattern created when a wet, bloody surface comes in contact with a second surface; a recognizable image of all or a portion of the original surface may be observed in the pattern |
Void | an absence of stains; reverse shadow |
Wipe Pattern | bloodstain pattern created when an object moves through an existing stain removing or changing its appearance |
