Spatters are created when blood is acted upon by force, and travels through.

The blood that dropped from 15mm is much smaller and the satellite spikes are less pronounced. The simplest type of blood spatter analysis is determining spatters from transfers. After impact, this drop formed a crown, spines, and satellites. The number of droplets and their distribution.

• spines—protrusions from the parent blood drop—protrusions from the parent blood drop • satellite spatter—smaller droplets that leave parent drop and land ne—smaller droplets that. Distinguish between spikes and satellites on blood spatter. The pointed edges of a stain that radiate out form the spatter;. Blood spatter analysis allows investigators to identify what transpired at a murder scene and make educated guesses about the victim’s condition.

When the volume of blood in the rim becomes too great for the formations to contain, the inertia of the force causes satellite spatter.

Given a series of blood spatter stains; These bloodstains take their shape without any accompanying satellite spatter. Be able to determine the direction that the blood was moving. Distinguish between blood spatter based upon blood dropping onto a smooth surface and a rough or textured surface.

The satellites can be seen as the individual drops that are not. Spikes are attached to parent drop; Above are pictures of blood spatters, one from 15mm, another from 200mm. Small drops of blood that break of from the parent spatter when the blood droplet hits a surface.
