History Of Bloodstain Patterns Essay
Function of bloodstain pattern analysis Bloodstain pattern interpretation/analysis has been around for many years but has only really been recognized in the past several decades. This interpretation/analysis is like a very important tool that an investigator or forensic scientist may use to help them better understand what happened or what did not happen in a case where there was bloodshed. Discoverable through the examination of bloodstain pattern The information that can be discovered or obtained when examining bloodstain patterns can help in apprehending a suspect, corroborating a witnesses statement, interrogating suspects, allowing for reconstruction of past events and lastly but probably the most important exonerating an accused. All bloodstains can provide important specifics to an event that occurred during an incident, so they are always examined. This is a very crucial part of an investigation, but it is never 100%, errors do occur. ââ¬Å"Static Aftermathâ⬠There is such a thing called ââ¬Å"static aftermath.â⬠What an analyst evaluates is the static aftermath of an event; the shapes, volumes, patterns, number and size of bloodstains and their relationships to the scene.
