While conducting research for my current novel DEAD BURN, I realized that there are some very interesting forensic facts that may or may not be widely known to most people. I have physical notebooks and online file folders filled with information that I might use in upcoming stories. Basically, I like to have more information than I’ll ever need, but these are good reminders for crime fiction writing.
This is for all you armchair CSI buffs or crime fiction authors:
ABO blood groups:
This is a blood group system that was first proposed by Karl Landsteiner, an Austrian biologist and physician, in 1900. The system consists of antigens, substance that produces an antibody, found on the surfaces of red blood cells and the corresponding antibodies in the serum.
The approximate percentage of the U.S. population blood type:
Type A (42%)
Type B (12%)
Type AB (3%)
Type O (43%)
These are characteristics found in a specific material that are required by wear or by some accidental or other non-repeatable circumstance during the manufacture. It can also be described as a small defect, which gives a unique or “accidental” characteristic.
These characteristics can be found in tire treads, shoes, bullets, glass, plastic bags, and many other items. These characteristics are extremely important in the identification and comparison of evidence.
This is one of the four nucleotide bases the compose DNA.
This grayish, wax-like substance forms from the result of the slow chemical reaction between body fat and water during the decomposition process.
This is the rate of cooling of a body after death. It can be difficult to determine the time of death because many variables are taken into consideration, such as temperature, fat on victim, and the exposed area where the body was found. For more information, check out The Body Farm.
This is the material used as filling for cavities or restorative dentistry. For identifying a victim, dental records are extremely effective.
This is a type of body measurement used to identify individuals. This term is often associated with a system of body measurements first developed by Alphonse Bertillon, a French law enforcement officer and biometrics researcher, for identification proposes, but it was replaced by fingerprinting in the early 1900s.
