¶ … Splatter
The author of this report has been asked to construct an experiment surrounding the spattering patterns of liquids at crime scenes or anywhere else where the way a drop hits and makes a pattern on a surface matters. The common example of this would be blood drop patterns at verifiable or known crime scenes. Indeed, the way in which drops fall would tend to indicate how they fell, from how far they fell, from what angle they hit the surface and what the likely cause of all of the above was. This report will list a problem statement, a hypothesis, the procedure that will be used to test the hypothesis and address the problem and a conclusion. The safety precautions used will also be listed and described. While blood and other fluid spatter can lead to varying or wild conclusions, there are certain patterns and trends that are fairly simple to make out and establish but the outcomes found will vary based on things like temperature, the surface that is being dropped, the angle at which that surface is situated and the texture of the surface.
Problem Statement
The problem to be addressed is whether one would see different patterns and outcomes when undergoing experiments with blood spatter based on variations in things like the surface the blood is being dropped on, how far a fall the drop takes before it hits, whether angle makes a difference in what happens when the blood hits the ground and so forth. It is reasonable to assume that there would be some, if not a lot, of variation based on the surface angle and composition.
Hypothesis
The hypothesis for this work will be as follows and it has to be broken into multiple parts:
The height from which the blood drop falls is going to impact the average width that is exhibited by the resulting drops
The width of the ensuing blood drops will probably be round when hitting the surface but will almost certainly vary in width based on how far up the drop comes from.
The change with the blood drop width as compared to height may be linear but it may also resemble a curve if graphed.
The angle of the plane that the drop hits will have an impact on what shape and direction the blood drop takes. Gravity will obviously have an impact when the angle is slanted...
Crime Scene Challenges: How to process the crime scene safely Retrieving a body from the water so it can be analyzed appropriately is a considerable forensic challenge. In most crime scenes, everything is supposed to remain 'as is' until forensic personnel investigate. However, a crime scene located near a body of moving water usually means that the body must be retrieved as quickly as possible, to prevent further damage to the evidence.
Crime Scene Investigations: Many crime scene investigations revolved around safeguarding the crime scenes, protecting physical evidence, and gathering and transferring the evidence for scientific evaluation. This process is based on the role that physical evidence plays in the overall investigation and determination of a suspected criminal activity. Notably, the ability for physical evidence to play its role in the overall investigation process is dependent on actions that are taken early enough
Crime Scene Evidence Laying the Foundation for Crime Scene Evidence In recent decades, significant advances in forensic technology and communications have revolutionized the art of collecting, sharing and using evidence to prosecute and convict accused criminals. These advances definitely make it easier for law enforcement (police and prosecutors) to put criminals away, but this not at the expense of the accused's constitutional rights to a fair trial. Therefore, courts have established different

4-8). While these standard procedure are relevant in the preservation of any crime scene, certain specifications exist when dealing with the unique challenges associated with the different types of crime scenes including homicides, rapes, arson, and nighttime crime scenes. For instance, in the case of homicide, as well as the aforementioned steps, the area must be preserved for trace evidence such as fingerprints. In the case of rapes or sexual
Crime Scene Investigation: A homicide crime has just occurred at a convenience gas station that included the presence of an employee, a mother, and her 15-year-old son who were witnesses of the crime. Upon arrival at the crime scene as a crime scene investigator at 3a.m, I found the deceased victim with an obvious gunshot wound in the chest as the first officer informed me of the present witnesses.
