Organic and Inorganic Evidence Johana Maria CRJ 311 Forensics Henry Johnson July 31, 2011 Organic and Inorganic Evidence In this paper I will decribe the difference organic and inorganic evidence. Compare the strengh and weakness that each have. The significance of either organic or inorganic evidence as it travels through the justice system from the crime scene to prosecution. Some of the example of inorganic evidence is paint and glass. This two are the most important evidence that contains inorganic compounds. Paint tends to be inorganic in nature.
The white, red, yellow pigments of paint is inorganic by nature. Organic compounds are based on carbon these are found only on living things. Inorganic is the opposite it doesnt come from living things its from synthetic fibers like polyester or nylon are carbon based but are not found in plants or animals. From a forensics science point of view both inorganic and organic compounds are very important when found in items of evidence. Organic compounds are extracted from living beings while inorganic compounds are created either due to natural processes or in the laboratory.
Inorganic compounds contain metal and other elements while organinc compound contain carbon. Another example is that inorganic compounds can make salt while organinc does not. Organic compounds are biological and inorganic are mineral in nature. Organic compound can form long and complex chain of molecules(hence form polymers) whereas inorganic compound does not have this capacity. Organic compound are source of energy for human life(as food) whereas inorganic compound act as catalyst. Inorganic trace evidence, which includes hairs, fibers, tool marks, allistics, glass, paint and other evidence that might be found on or around a crime scene. The second is organic trace evidence, which refers to trace evidence that comes from a human or animal. Fluid is organic compound. If is left at a crime scene this most likely will include saliva,semen,sweat, and vomit which it can be run through a large amount of test at the medical examiner lab. One of these is polymarking which is DNA. Fluids might also tell the examiner that if the fluids they found might have any type of disease or defect.

It will also tell whether it was a male or female. In some cases fluid might give law enforcement an idea of how the crime occurred. Another exmple of inorganic evidence would be feces the composition varies widely depending upon the diet and health of the defecator, but broadly speaking fecal matter consists of water, inorganic salts, food residues, amino acids and digestive enzymes, cellulose and fiber; mucus, blood, bacteria, and parasites are also commonly present.
There has been no reports of any scientific study undertaken to determine the health effects of customary shit-eating, but from the standpoint of contagion it is probably not a great deal more (though certainly it is not any less) dangerous than the consumption of semen, menstrual blood, etc. , all of which, as noted above, may be risky.
