History Of Bloodstain Patterns

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.

“Static Aftermath”
There is such a thing called “static aftermath.” 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.

Timeline of bloodstain pattern analysis
Surprisingly to me the study of bloodstain patterns has been going on since the 1800’s. On the following page is a time line showing the history of bloodstain patterns interpretation/analysis. The timeline I made begins in the 1860’s and goes through the 1970’s, not every significant moment is included on this particular timeline. 1970’s – MacDonell worked under a LEAA grant, and completed 3 different articles through the 1990’s. He has trained many in law enforcement and has developed courses to continue to train analysts. 1970’s – MacDonell worked under a LEAA grant, and completed 3 different articles through the 1990’s.
