where
= length of ellipse (major axis)
= width of ellipse (minor axis)
Keep that equation in your back pocket...you'll be tested later.
Forensic Science is used to establish what has occurred in a given scenario based on attained evidence. It is a form of piecing together an historical disconnect, ultimately creating a portal into the past.
At worst, assumptions have to be made to establish leads that may or may not shed light on reality. However every lead, based on assumptions or not, have the potential to point the investigation in the right general direction. So all options must be explored where evidence is scarcely available.
To the casual onlooker, the alleged crime associated with Case Study #3 was abundantly violent in nature. Blood pooled, splattered and strewn about the room in all directions.
Once blood leaves the body, the fluid behaves not unlike fluid does and adheres strictly to the physical laws of nature. The specific physical considerations in this particular case are gravity, viscosity, and of course, everyone's favorite, surface tension. As soon as blood leaves the body, gravity becomes a major factor in the equation...simple enough. Viscosity is the resistance to the flow of blood as it exits the body. This directly effects how the blood responds to gravity. Surface tension is what defines the specific shape the drop of liquid forms as it travels and finds purchase.
One factor pulls. One factor resists. One factor has tension.
All of these physical considerations are used to determine the point of origin where the blood becomes acutely aware of its sudden liberation, which in turn reveals a variety of trajectory angles. This defines the Alpha, Beta and Gamma.
Everything in threes.
Alpha is the impact angle of the blood splatter path moving out from the surface, Beta is the angle of the blood splatter path pivoting about the vertical axis and Gamma is the angle of the blood splatter path measured from the true vertical (plumb) of the surface. All three angles are related through a trigonometric equation (shown at the top of today's entry).
Of course, this is all an alien language to me, and to be perfectly honest, I haven't the first clue what it all means.
Forensic studies have been conducted in our crime scene, the blood thoroughly analyzed, all angles measured, and although the research offered no absolutes, one thing is quite clear. Something isn't quite right according to the responding crime scene investigators...they just are not completely certain as to what that something is. The angles are consistent with the height of our alleged victims and/or suspects, but if one, or both, were bludgeoned, it occurred in a fairly unique manner. The physical laws of nature paint a messy, red picture, but it's a picture of ambiguity, at best.
The findings to date are confounding and inconclusive.
Aside from that, investigators have started a backstory of the two characters in play. Speaking to family members, friends, coworkers, acquaintances, gas station attendants, grocery store baggers, pets and anyone that may have witnessed anything at all that may offer a shred of insight as to the parameters and circumstances that led to whatever the hell happened in that room.
Thousands of dead ends may derail progress in the investigation, but only one obscure detail is needed to shed some light into the matter. Although investigators hope that light is not merely the flickering of a flame, casting its deceptive shadows.
Perhaps science and trigonometric equations do not always reveal the truth. That's not to doubt the legitimacy of their logic...but the answers they offer are only as relevant as the questions being asked.
Today's Jazz Hands are plumb.
Day two-hundred and fifty-three complete.
