There are many important factors in crime scene investigation, one of those involves serology and observing the blood spatters at a crime scene. Many steps are taken when dealing with blood at a crime scene, some of which are if the substance is actually blood, blood typing, discerning the origin of the blood, the direction of travel of the bloodstain, what weapon would have caused the bloodstain, etc. Serology and dealing with bloodstains can be a very difficult task for criminalists because blood also deals with DNA, what type of blood it is, identifying who the blood belongs to, what caused the bloodstain, and what direction it originated from. To understand serology, it is probably best for one to understand the nature of blood first. …show more content…

Carefully and thoroughly analyzing the significance of the position and shape of blood patterns along with their origin and trajectory is very important in an investigation. The process is sufficiently complex and should only be done by an examiner who is experienced in such determinations. The interpretation of bloodstain patterns is the most important of all and requires carefully planned control experiments that use surface materials comparable to those found at a crime …show more content…

There are many steps criminalists must take if they find a bloodstain at the crime scene such as first identifying if it is blood, measuring the bloodstain, analyzing it, testing it and many other steps. By observing blood spatters and their characteristics, criminalists can discern what weapon was used, the origin and direction of travel of the blood spatter, the velocity of the spatter, how many times was hit or shot, etc. Examining and observing bloodstains or spatters is extremely important when there is no body at a crime scene.

    The first step is to place a drop of distilled water on a sterile swab and swab a small portion of the suspect substance, The place the swab against a presumptive blood test and an immediate color change should occur if the reaction is positive. If the stain is negative the suspected blood stain may be ignored. If the reaction is positive an evidence number is assigned to the suspected blood and the stain is photographed and measured. The forensic technician should note the stain was collected due to a positive reaction. The blood is then collected and packaged, and the package is sealed and labeled for identification Upon collecting blood if the blood is wet a sterile swab should be rotated in the stain, transferring the blood to the swab.

    Englert explained that high velocity blood splatter is blood that has been hit by something at rapid speed. For example, a bullet which was used in the murders of Kim Camm, and her children. According to Englert, the bloodstains on the shirt, socks, and shoe collected from the defendant were a result of high velocity impact spatter. Rod Englert testified that this was an indication that the defendant was “within four feet of the shots when they were fired” (Mckay, 2002). However, the defense argued that the bloodstains found on the items belong to David Camm were merely the results of transfer.

    Spattered blood is a random distribution of bloodstains that vary in size that may be produced by many mechanisms. The size and quantity of spatters produced by a single mechanism vary significantly. The amount of available blood and the amount of force applied to the blood affect the size range of spatters. Spatter is created when sufficient force is available to overcome the surface tension of the blood. The amount of force applied to a source of blood and the size of the resulting spatter vary considerably with gunshot, beating and stabbing events.
