Organic and Inorganic Evidence

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, ballistics, 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

    Trace evidence is based on Locard's exchange principle which contends that every contact no matter how slight will leave a trace . The trace is normally caused by objects or substances contacting one another, and leaving a small sample on the contact surfaces. Foreign objects or pieces of material present at a crime scene and tracing its origin can assist in an arrest and conviction the same way finding some trace from the victim or crime scene on a suspect can have a strong impact on a case. Trace evidence, though often insufficient on its own to make a case, may support other evidence or even prompt a confession. Because trace evidence can be any number of things, from a paint chip to a piece of glass to plant debris, there are numerous different methods used for analysis. This essay is to only cover the chemistry unit in the analysis of synthetic material, blood and urine samples, to explore how their work helps in the general aspect of crime investigation and how cases are built using this type of trace evidence.…

    4) Most organisms’ molecules are based of carbon, therefore most carbon compounds are organic. 5) While organic compounds are made mostly of carbon atoms, inorganic compounds are not made of carbon atoms 7) Functional groups help influence the characteristics of the molecules they compose and the chemical reactions the molecules take part in. For example, the hydroxyl group, one of the functional groups, attaches to molecules and can make them polar. 9) ATP is used by cells to gain the energy it needs, so the cell can take part in chemical reactions that it needs to execute so organisms can survive.…

    The search for physical evidence at a crime scene must be done thoroughly and followed by the protocol. How the criminalist will decide to execute the crime-scene investigation depends on the size and the locale of the area, as well as on the actions of the suspect(s) and victim(s) at the scene. It must be considered that physical evidence can be anything, from a massive object to a microscopic trace, however, some evidence are clearly visible but others need to be examined in the laboratory in order to be detected. Physical evidence must be processed in a way so as to prevent any change from happening between the time that was collected on the crime scene and the time it is received by the laboratory. When collecting physical evidence from a scene, any criminalist must be aware of the fact that recovery of one type of evidence can destroy another.…

    In order for food to be called organic, it must be grown without the use of synthetic fertilizers or pesticides. Although organic foods carry very minute levels of toxin naturally present in them, they are not harmful to us at these levels. By not using synthetic fertilizers and pesticides, organic foods can naturally develop the nutrients and vitamins that a person needs to maintain a healthy, well balanced diet. Keeping these foods the way they naturally grown allows them to develop larger and more full of these valuable items that would be reduced because of the many chemicals and pesticides used to grow the convention foods. As to whether organic food is tastier, is up to the individual. Many professional chefs and home cooks prefer to use organic food when possible because they feel the flavors are stronger and taste more natural. Organic food is richer in color; therefore making the dishes not only taste better but help also to create a more…

    Forensic evidence is scientific evidence provided by expert witnesses, obtained by scientific methods such as ballistics, blood testing, and DNA testing. There are two major types of forensic evidence, there is fragile or ‘transient’ evidence such as, hairs, fibers, glass, fractured objects, fire accelerants, skin cells; found on items touched or worn, barefoot impressions; latent and in blood, shoe and tire impressions, toolmarks; focus on point of entry, body fluids; blood, semen, and saliva, gunshot residue or patterns, and latent fingerprints, and there is solid or ‘tangible’ evidence such as, firearms, unfired cartridges, fired cartridge cases, fired bullets, other weapons; knives, metal bars, bats etc.., computers and devices, documents; checks, notes and receipts, drugs, and paraphernalia (MSP,…

    Preservation Of Evidence

    Many cases are won or lost by the weight of the prosecution’s evidence. Through methods of discovery of evidence, both the prosecution and defense have equal opportunity to develop evidence they believe is needed to prove or dismiss/ reject claims. Trace evidence and the preservation of evidence are very vital in any investigation. These two components are two of the most important things that can help investigators find their suspect(s), and lock them up or if done without proper care, the preservation of evidence or lack thereof can possibly make or break a case. Investigators taking the time out to pull trace evidence off of their victim(s), and placing it in whatever object is fit to hold and preserve the evidence, is very vital, because…
