The modern era of bloodstain-pattern analysis began when a small group of scientists and forensic investigators started testifying in cases, as experts in a new technique. Description the science of bloodstain pattern analysis can assist investigators in making determinations, such as, relative positions of the victim or suspect, the nature of the force and weapon used, and the approximate number of blows struck during an assault. Bloodstain pattern analysis: is the examination of the shapes, locations, and distribution of patterns of bloodstains, in order to provide an interpretation of the physical events that gave rise to their origin.
Bloodstain pattern analysis: is the examination of the shapes, locations, and distribution of patterns of bloodstains, in order to provide an interpretation of the physical events that gave rise to their origin. Bloodstain pattern analysts can confirm or refute assumptions made about the crime or statements made by suspects and witnesses based on their analysis steps for becoming a blood spatter analyst bloodstain analysis requires a meticulous and thorough understanding of the properties of blood and the human body. Blood stain pattern analysis report, any specialist is able to understand the mechanisms behind each pattern a standardized scientific approach of blood stain pattern interpretation has been defined by ‘‘the scientific working.
This course will teach students the uses and limitations of bloodstain patterns as they relate to violent crime analysis lessons include comprehensive laboratory exercises in our dedicated blood spatter rooms and a workbook with relevant questions related to their findings. Bloodstain pattern analysis (bpa) has been used in criminal investigations since the 1800s like many other disciplines from the early days of forensic science, its use and acceptance occurred.

The advanced bloodstain pattern analysis workshop is a comprehensive, 40 hour course designed for the student who has previously attended a 40 hour introductory bloodstain pattern identification workshop. Though bloodstain pattern analysis (bpa) can be a subjective area of study at times and often reliant on the experience of the investigator, the idea that blood will obey certain laws of physics enables the examination of blood at an incident scene and on items of evidence to offer at least an insight into what was likely to have occurred. Blood spatter patterns are created when an exposed blood source is subjected to an action or force greater than gravity (internally or externally) the size, shape and number of resultant bloodstains will depend generally on the amount of force applied to the liquid blood.
