MICROANATOMY

Detailed explanation-1: -Pools-a bloodstain pattern created when a source of blood remains stationary over a surface causing an accumulation of blood. If the bleeding victim moves to another location, there may appear to be droplets or smearing connecting the first location with the second.

Detailed explanation-2: -Transfer Stain-A bloodstain resulting from contact between a blood-bearing surface and another surface.

Detailed explanation-3: -Swipe Pattern-the transfer of blood onto a surface not already contaminated with blood. One side is usually feathered which indicates the direction of travel. One common pattern at scenes is a hair swipe-a long thin fine line transfer.

Detailed explanation-4: -Satellite Spatter – Small droplets of blood that are distributed around a drop or pool of blood when the blood impacts the target surface. Saturation Pattern – Bloodstain pattern resulting from an accumulation liquid on an absorbent material.

Detailed explanation-5: -Distinctive bloodstain patterns termed “cast-off “are frequently found at such scenes. A cast-off pattern is defined as “a bloodstain pattern resulting from blood drops released from an object due to its motion” 4.
