Say to Explorers: Bloodstain pattern analysis is a discipline of forensic science that examines bloodstain patterns at crime scenes. In terms of physics, BPA reconstruction is a complicated problem in fluid mechanics that involves tracing the behaviour of blood, under various forces and ambient conditions. You can also ask your math teacher for help and for more sources. deaths. Forensic science includes many areas of study, such as criminalistics, engineering science, as well as pathology and biology. Blood spatter analysis can indicate the movements of both the offender and the victim. Good prices and service!
