Flow Pattern A bloodstain pattern formed by the movement of large or small amounts of blood as a result of gravitys pull. Created when a blood covered object flings blood in an arc onto a nearby surface Commonly produced by a bloody fist or weapon while delivering blows Features of patterns are affected by the size of object amount of blood and direction of movement May determine minimum number of blows by counting and pairing forward and backward patterns.

A change in the shape and direction of a bloodstain due to the influence of gravity or movement of the object. Flow Pattern A bloodstain pattern resulting from the movement of a volume of blood on a surface due to gravity or movement of the target. Flow patterns flow patterns are made by drops or large amounts of blood flowing by the pull of gravity.

Forward Spatter Pattern A bloodstain pattern resulting from the blood drops that traveled in the same direction as the impact force. The blood pattern is much larger than those of medium velocity and high velocity. A typical pattern of blood spatters that are in one line occurs.

It occurs when an object impacts the source of the blood. Passive flows originate with blood deposited on a surface such as an arterial spurt. This kind of spatter is normally produced by gravity alone by a minimal force.

This is commonly caused by the force of gravity such as blood dropping off a finger or hand.
