Satellite Spatter Blood Crime Scene Reconstruction Stain Pattern Analysis Ppt Download
A bloodstain’s apex always indicates the. Spines, scallops, or even satellite stains can form when the dimples on the rim separate minimally from the droplet structure; Each method considers the same basic bloodstain pattern.

Number of satellite stains increases with increased drop number and impact velocity. • 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. Secondary spatter or satellite spatter occurs when blood drops fall into a preexisting pool of blood, resulting in a distribution of spatter around the periphery of the parent stain.
After impact, this drop formed a crown, spines, and satellites.
Secondary spatter is a result of an event other than the blood loss event and refers to satellite spatter. This work characterizes fundamental features of static drip patterns simulated for. The number of droplets and their distribution. It is crucial that blood patterns are carefully documented and preserved in their original state so they can be.
The satellites can be seen as the individual drops that are not. When the blood contacts another surface or additional blood on the. Blood spatter analysis, also known as bloodstain pattern analysis, is a critical tool used by forensic investigators in crime scene reconstruction. Impact spatter is the only pattern we analyze for the area of origin to.

Classifying bloodstains is an essential part of bloodstain pattern analysis.
Various experts have developed methods. Therefore, most blood spatter begins with a perfect circle. Blood spatter patterns are often present at the scenes of violent crimes. From the parent drop, small drops can break off and create satellite spatters.
These satellite spatters can tell blood analysts what direction the blood is traveling. These bloodstains take their shape without any accompanying satellite spatter. When analyzing bloodstain patterns, first divide the stains into three basic categories: Small drops of blood distributed around the main blood droplet.
