As an author, I’m often like a cat seeing something shiny, and I can find a research opportunity anywhere — so imagine my lack of surprise at finishing a book on my TBR list and being so caught up on one detail that I’ve spent the last couple of days mulling over the idea of blood spatter analysis.
The use of science and mathematics to help solve crimes, I find super fascinating, and forensic scientist have my utmost respect. I so look forward to meeting a real life Gil Grissom, and having a day at the famous Body Farm — well, one can always hope.
From my novice understanding of blood spatter analysis, since blood is a biological liquid, and when combined with physics and mathematics, it can tell a keen eye a lot of what transpired at a crime scene. Such as if a person was stabbed and stumbled away, due to how the droplets of blood would form on the floor based on distance and speed. The crime scene’s blood spatter can even tell the expert eye if the deceased was dead at the time of the creation of the spatter or if it was done postmortem.
Blood stain analysis can help “corroborate a story” or “refute a story” to see if statement fits a story or not.
Additional information on blood spatter analysis.
Although science has increased our understanding of blood spatter analysis, and many might consider it a new field, we’ve made great advances since the 1950s Sam Shepherd case. Modern technology has allowed us to work in tandem with the laws of physics to better understand the blood spatter as evidenced at violent crime scenes. This analysis has resulted in experts testifying as to how blood spatter works and even providing a defense for accused based on a lack of spatter present.

So, when it is all said and done, and I’ve printed out my charts, watched numerous videos and spent a tremendous amount online researching the details of this topic, I can’t help but hope to be able to infuse the next story with this great information.
Of course, this is only one area of forensic science, but as years of watching CSI has shown me, the devil is in the details, and often that detail is a simple drop of blood.
