In general, satellite spatter around parent stains will have the pointed end facing against the direction of travel. As the stain becomes more elliptical in shape, its direction becomes more …

Expirated spatter - is usually caused by blood from an internal injury mixing with air from the lungs being expelled through the nose, mouth or an injury to the airways or lungs. Expirated spatter …

Bloodstain pattern analysis (BPA) is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed. Analysts examine the size, shape, distribution …

Nov 15, 2017 · A bloodstain pattern resulting from the transfer of blood from a blood-bearing surface onto another surface, with characteristics that indicate relative motion between the two …

SPATTER VS TRANSFER: The simplest type of blood spatter analysis is determining spatters from transfers. Spatters are created when blood is acted upon by force, and travels through …

Parent stains under 3mm are most likely some form of dynamic spatter (e.g., impact o, expectorate), and if the analyst encounters stains in excess of 25mm, they are less likely to be …

These bloodstains take their shape without any accompanying satellite spatter. Small drops of blood distributed around the main blood droplet. The number of droplets and their distribution …

The first, main blood droplet that strikes a surface is known as the parent drop. From the parent drop, small drops can break off and create satellite spatters. These satellite spatters can tell …

Satellite Spatters– Small drops of blood that break of from the parent spatter when the blood droplet hits a surface. Spines– The pointed edges of a stain that radiate out from the spatter; …
