Hair/Fiber

Hairs, which are generated mostly of the protein keratin that, can be classified as slender outgrowths of the skin of mammals. Each species of animal possesses hair with distinctive length, color, shape, root form, and internal microscopic features that differentiate one animal from another. Significant variability also exists in the types of hairs that are established on the body of an animal. In humans, hairs found on the head, pubic region, arms, legs, and other body areas have uniqueness that can determine their origin. On animals, hair types include coarse outer hairs or guard hairs, the finer fur hairs, tactile hairs such as whiskers, and other hairs that originate from the tail and mane of an animal.


Because hairs can be transferred at some stage in physical contact, their attendance can link a suspect to a victim or a suspect/victim to a crime scene. The types of hair recovered and the condition and number of hairs found all impact on their value as evidence in a criminal investigation. Comparison of the microscopic characteristics of questioned hairs to known hair samples helps determine whether a transfer may have occurred.


These are 3 main category of hair analysis:

chemical assys used to judge the use of illegal drugs, the existence of weighty metals in the body, and to experiment for nutritional shortage

the core of the hair is normally used for the DNA analyses

microscopic difference if hair can be determined if the hair from another place if they are the same person or animal.

Hair is conceived of 3 coatings
medull
cortex
cuticle

Positioning a suspect at a sight of a crime is what it is all about. 1 of the traditions that this can be done is by finding fabric fibers similar to those from the victim’s clothing or the crime scene on the clothing or person of the suspect otherwise uncovering fiber evidence at the crime scene that can in some way be tracked back to the suspect.

Fibers are regarded as a type of trace evidence that can be transmitted from the clothing of a suspect to the clothing of a victim at some point in the commission of a crime. Textile fibers can also be transferred from rugs or blankets; between two individuals; between an individual and an object or between two objects

Blood Types

Blood types were discovered in 1900 and 1901 at the University of Vienna by Karl Landsteiner in the progression of attempting to figure out, why blood transfusions at times initiate death and at other times save a patient. In 1930, he finally earned the Nobel Prize for this discovery.

All humans and many other primates can be typed for the ABO blood group. There are four primary types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types. The precise combination of these four components determines an individual's type in most cases. The table below shows the possible permutations of antigens and antibodies with the corresponding ABO type ("yes" indicates the presence of a component and "no" indicates its absence in the blood of an individual).

The RhD System, some people are A+ (A positive), meaning they have the Rh antigen, those who are A- (A negative) do not have the Rh antigen.

84% of the population is Rh positive

I think that now in today’s time scientifical improvements are being made, so now less people are dying, which I personally love the idea of

Crime Scene Invesrigation

Evidence


1. Blood Samples: A and B


2. Fiber


3. A Fake Gold Chain


4. Size 8 shoe print


5. Scented Cotton ball that smelled of shampoo, possibly organic shampoo


6. Expo Marker


7. Hair Samples of an potential asian, dyed hair, and possibly gelled or greased hair





Possible Suspects: Mike Kelly, Kooladria Jones, Sam Tilson, Jenny Cho, Ralph Johnson, and Kevin Popadines





Possible Scenario
Using the evidence found it is clear exactly what happened.
1. It was suppose to just be a fun evening, with Kevin Popadine's wife's sister, so on this particular day he whisked Jenny Cho away to get her mind of off her horriable husband, but trouble struck. Always envious of her sister Jenny threatened to tell Popadine’s wife a deeply disturbed lie, and that couldn’t happen to Popadine’s, a young teacher who so far has had the perfect life. So they fought, Jenny struggled to get away but she was no match for the 6’0ft Popadine’s. Unable to think of anything else, Cho sprayed her perfume for his eyes but barely missing and getting the wall where the sample was collected. An angry Popadine’s than struck Cho, causing her eye to bleed, than a desperate to survive Cho grabbed her hair brush and swung at Popadine's, hitting him right in the jaw and ran desperate to survive and get away from the angered Popadines. The other evidence that we have found have yet to have been explained, however it does seem logical for the fake gold chain to have caught onto the door as she ran out of the cabin, and as for the expo marker it is highly acceptable that Popadine’s being a teacher placed it on the kitchen table and later forgot about it.
