Hair Analysis : Forensic Science

African American women's health, hair politics, and physical activities. Studies show that African American women tend to pay more attention to their hair instead of their health issues. Researches came up with a theoretical argument to figure out why hair matter for some women. They discover that hair presents a barrier to exercise in that the time and economic restrictions involved in maintaining a hairstyle post exercise for physical activity as prohibitive. This study provides some perception about the relationship between hair and health for African American women and suggests that extra attention is justified to address views about beauty ideals and hairstyles as a barrier to exercise (Versey, 2014, p. 2015)

In the case of Joann Curley the key physical evidence that was used to solve this case was hair evidence. Hair evidence when properly collected and submitted to the laboratory accompanied by an adequate number of standard/reference samples, can provide strong corroborative evidence for placing an individual at a crime scene. In the case of Joann Curley, evidence was searched for and collected from their house, Roberts’s autopsies, and Roberts’s workplace. In addition, they also tested Roberts’s co-workers for thallium after they were questioned, including Joann and their daughter. During the investigation they figured out thallium was present in Roberts’s workplace which led to believe that his co-workers may have had involvement and pulled a prank on him, as Robert was known to have pranks pulled on him. This theory went down the drain after investigators tested the air and surface of Roberts’s workplace, which ended up being eliminated as possible source for exposure to thallium. Investigators then decided to look closer to home and found thallium located in Roberts thermos cup that he never took to work and decide to have a second autopsy of his body. During the autopsy forensic toxicologists Michael Baden and Fredrick Reader’s used hair evidence collected during it to analyze for traces of thallium because a substance like thallium will circulate through the blood stream and attach to the root of the hair like a cell, it then stays on the hair shaft and grows

At the scene of the crime a hair was found near Anna Garcia. After viewing and testing the hair, we concluded that the hair belonged to Erica. The unknown hair had the exact same thickness and color of Erica’s hair. The hair at the crime scene had a similar cuticle to Erica’s. Both Erica’s hair and the one at the crime scene had the same cortex as well. We believe that Erica’s hair was brought to the crime scene on a piece of clothing by Alex Garcia(Anna’s ex-husband). When Alex came to murder Anna a hair of Erica’s must have fallen off when Alex was doing his deed.

For example, you would not associate blond hair with asian or african americans. So here is where this information intertwines with the murder case of Dan Fitzpatrick. The hair that was found on Mr. Fitzpatrick was short and circular inferring that it came from the head and from a male because of the length. It also showed characteristics of being from someone who is african american. As you see from the diagram the cross-section is very flatten and oval like compared to the caucasian. That is where the curliness comes in. The hair was also dark. So how does that make Bradley Cummings the murder you may all wonder? Well, Mr. Fitzpatrick just fired Mr. Cummings for violent behavior. Why wouldn’t Cummings want to get rid of Fitzpatrick? He had

How hair played a role: anagnos was stabbed twenty times and was hut in the head multiple times. Then they found hair that anagnos clenched in his hand that came from the suspect. The hair was sent to a private lab for testing, and figured

We analyzed 3 pieces of evidence for hair. We collected hair from the Victim, the Victim’s Car, and the Cabin. The Victim

Well those are some basic facts everyone should know about hair for this case. Now that everyone has back round information about hair I can explain why I believe a particular suspect is a match to the hair found at the crime scene. I received four different pieces of hair from each of the suspects, which I labeled A-D. Then I analyzed them all under a microscope on wet, latex and water mounts. After that, I actually got the hair from the crime scene and labeled it “Evidence” and analyzed it under a microscope on wet, latex and water mounts just like I did to the suspects hair.

If flaws in testing techniques become noticeable and extreme action is not taken to control these issues, society will begin to test the validity of “forensics” as a whole. Referring back to the Motherisk case where a lack of education and professionalism took place, people began to question the science of hair testing and the reliability of investigators, and because of this many cases involving this particular laboratory had to be reevaluated (1). Employees in the Motherisk case were not informed that they were considered expert witnesses in the cases they took part in, and part of their job was to also maintain a bias free work zone, these are crucial mistakes which can lead the way for many wrongful convictions (1). The Motherisk case also demonstrated the importance of judges playing an important role in raising issues of reliability of evidence where people in question simply cannot afford it (1). Prior to final decisions judges should have all the evidence regarding the specimen of hair and the pros and cons of assessing this as a valid science (1). Only the best sciences should ever be considered in the courts. In the courts “hard science” should always be picked rather than a “soft science” because it is scientific proof (1). Hair follicle testing may one day become one of the easiest methods of testing, and will allow

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;

Introduction: Forensic science is the application of science to laws, and it is instrumental in a criminal investigation and the trial that follows. It can help investigators deal with new crimes more effectively, and it can also shed new lights on cold cases. The biggest news of last month is the apprehension of the Golden State Killer, mostly as a result of DNA evidence, which was not available forty years ago, when he committed those crimes. Nevertheless, DNA is just one part of forensic science, and its development in history is accompanied by those of others. Another crucial aspect of forensic science is the trace evidence. French scientist Dr. Edmond Locard formulated one of the most basic principles in forensic science. The Locard’s

Physical evidence surrounds the known end tale to a story. Since the beginning, crime scene investigators have seek the infallible nature of human identification. It can achieve its optimum value to help investigators reconstruct the crime scene to piece together the sequence of events. The contents of physical evidence, best known as real evidence, consist of those tangible particles such as hairs, fibers, fingerprints and biological material (blood, semen or saliva). It is stated in context of the “Locard’s Exchange Principle”, whenever a person enters into a room, they will always leave a trace of evidence. Physical evidence is subjective to being the only way to reliably place or link someone(s) to the crime scene.

After concluding my observations and organizing my data it is clear that a couple of things don't affect the results of this observation. compared to the other options that were available to observe for this project. One of the other options was the length of men's hair. I think comparing male hair length on campus to the total male population would have some interesting results. Young generation males are wearing the “man bun” more and more. I think this could be a result of students going to a University, and not having the time, energy, or money to set up a hair appointment in a new town. So they end up just growing their hair out, because it's easier. Another option to observe was women's sleeve length, but this is really going to be impacted

The only way to know if Wen By Chaz delivers beautiful hair without trying it yourself is to read a review with pictures from a self-described hair care fanatic who works in a hair salon. Emily McLure's review on Bustle is very informative as she includes pictures on her hair from day one of the test to day seven.

Unwanted facial and body hair can be a source of distress for both men and women. Since the early 1990 laser has become a widely accepted and a safe method for treatment of excessive hair growth provided it is done by trained hands. Excerpts from the talk with Dr.Anshul Jain , M.D. (Skin) regarding myths about Laser Hair Removal.

3B curls are tighter curls than 3A, but are still fairly “loose”. The circumference of this hair type is similar to the same of an average Sharpie marker. This texture is not as shiny as the 3A hair but is still soft to touch. 3B hair can be dense and/or coarse. This hair type is when your hair starts falling in love with each other and starts knotting up. This hair type is prone to drying. 3B hair is fairly easy to straighten. Model Crystal Westbrook has 3B
