Blood Splatter expert witness
As an expert witness on the topic of blood splatter, I am able to recognize the crime at hand just from an analysis of the crime scene. One major detail that is important to take into consideration with blood splatter is the shape of the drops. A circular drop of blood would suggest that the blood was dripped straight downward off of the victim. A drop with a tail, or a more ovular shaped drop of blood would suggest that the blood was flung off of the victim from an angle. This is very important to look into when determining a point of origin that the blood came from.
To determine the point of origin, there are two details that you must take into consideration. The first is the shape of the blood droplet (the width and length of it,) and the second is the distance it is from the spot of where the violence took place. Using the width and length of the blood droplet, you can divide the two to make a ratio. Using the arcsine of the ratio, you can then determine the angle at which the blood droplet hit the ground. The next step will give the most accurate information if it is done using a string.
To determine the point of origin of the blood splatter, the string must be attached to the point of the blood droplet at the angle that was determined from the arcsine, and strung all the way to the spot where the incident took place. once the string reaches the point of the incident, keeping the same angle, you have determined the point of origin. A given set of blood splatter that came from one violent action will string back to one point of origin.
Once you have determined the point of origin, you can make conclusions about the crime. You can determine what area of the room it occurred in and how high it was off of the ground. You can also determine what weapon was used using blood splatter analysis. If the blood was found to be flung in a scattered array, there is a good possibility the victim was
