I suppose there are some instances where it would be useful to se the cuticle of the hair, and certainly the presence or absence of the cuticle in a hair sample found at a crime scene could have some significance in terms of recreating differences or determining how the sample came to be present (e.g. If it was pulled out during a struggle or simply broke off in the normal course of daily activities, for instance), but from what I observed it would not be as useful in identifying individuals as the hair itself. The hair itself is also more useful in differentiating between species than is the cuticle, and certainly the differences in human and non-human hair make this distinction easily possible whether or not the cuticle is present, so its need in this experiment is not entirely clear to me.
The magnifying glass I...
Using this, I was actually able see the medulla quite clearly, including the separate segments of medulla that appeared in the animal hair strands. On the whole, I would say that the entire experiment worked for me, and made it clear that a strand of hair is much less the uniform and solid structure that I thought it was and is actually composed of many different structures and pieces that fit together to make the whole. Also, though hair is not really seen as a substantial thing normally, it seemed strangely both more and less substantial in different phases of the experiment, with the flashlight illuminating how close to nothingness it really is.
This is because inorganic evidence is mostly based upon running the data through an a central database like the FBI's CODIS to see if there is a match (Schoester, 2006, 31-42) The Strengths/Weaknesses of Inorganic Evidence A major strength of this type of evidence is it involves the physical collection of crime scene evidence. Evidences such as broken furniture or windows or are picked that is able to be positively identified
Forensic Chemistry Forensics is a very important part of a crime scene investigation. There used to be a time when murders or crimes were left unsolved due to the lack of evidence. However with the advances in technology and research in forensics, crime solving has become a lot easier. The branch of science, which helps out in finding out important evidence, is known as Forensics Chemistry. Forensics Chemistry employs methods, which
Blood Evidence A POTENTIAL AND VALUABLE LINK Blood evidence is an extremely valuable item in criminal justice (Schiro, 2011; NIJ, 2000; OSP, 2002; NFSTC, 2013; Bestino, 2013). It has the unique and undisputable potential of solving a case or a crime as it can accurately identify a participant or a victim in a crime. It can form a connection between a person and a criminal act, enhance or contradict a testimony.
arrest warrant and a search warrant. An arrest warrant pertains to the arrest and detention of a particular person based on what crimes the person has allegedly committed. Evidence is necessary to procure a search warrant. However, once it is procured, the person can be arrested when found and whatever property they have on their person and the car they are driving in would be subject to impound and/or retention. A
Take simulated anti-A, anti-B, and anti-D and place a drop onto the labeled sections on the plate 4. Using an clean dropped drop the questioned blood into each of the three sections 5. Using a clean toothpick for each section, mix the blood 6. The formation of clumps shows that there is that type of antigen in the blood. Observation: Blood: Anti-A serum Anti-B serum Anti-D serum Resulting Blood Type The victims' blood: Kenny-11811B3: No clumping No clumping No clumping O- Blood #1 found
Police Report On the afternoon of February 8, 2007, I received a dispatch call on a potential homicide at 1100 SE Lynn Boulevard, Prineville, Oregon. This location is the local high school, named Crook County High School.
