Bloodstain Pattern Analysis Examples

The human body runs on blood. Blood runs through the body carrying nutrients to where it needs to go. The blood of the human body is made up of millions of red blood cells, white blood cells, platelets, and is all carried in the plasma. Blood has special characteristics of movement when it exits the body. These characteristics can help a crime scene analyst solve a crime (O'Neil). In this log, one will learn about bloodstain pattern analysis and how it is used to help solve crimes. Bloodstain pattern analysis is portrayed throughout movies and television, most famously the television show Dexter. However, there is more to bloodstain pattern analysis than taking pictures and connecting string. There are three main categories of bloodstains: passive, transfer, and projected/impact stains. Passive stains can result from drops and pooling of blood, typically any stain that results from gravity acting on the injured body. Transfer stains can result from items coming in contact with an already existing stain, and swipes left behind and transfers such

One main question that still remains is, when exactly did bloodstain pattern analysis first develop the idea of using inverse sine to calculate blood spatter? I found information on the man who originally thought about studying the bloodstain patterns at a crime scene, but when did the idea of inverse sine become involved? Inverse sine has been around for hundreds of years and is common for finding angles. So, I conclude that Eduard Piotrowski, the original creator of the idea of studying blood, tied the idea of inverse sine to blood patterns and discovered that the formula works for studying blood. Another question I have is, why after all of the time through history has innovators not come up with a better way to analysis bloodstains? Technology has advanced exponentially through the years. However, there has not been a way to analysis bloodstains
