No two ear prints have ever been found the same, nor do ears change during a person’s lifetime. Ear prints can be lifted like fingerprints and classified like fingerprints. Ear prints can even be used to identify suspects of a crime scene. The uniqueness and stability of ears make ear prints recordable, classifiable, and identifiable.
Initially, ear prints are nearly as common as fingerprints and can be lifted with the same method. For example, Encyclopedia.Com reads that in a criminal case, “It is not uncommon for a perpetrator to put an ear to a door or window prior to entering a crime scene in an effort to determine whether the area is occupied, or for an ear print to be left against a wall or other hard surface during a struggle or when a body is being positioned or moved”. Ear prints leave behind

For example, in 1910, a prisoner’s ear was linked with an ear print at a crime scene due to an obvious peculiarity of the ear, and the prisoner was convicted of the crime. In order to identify a suspect with an ear print, three to five prints of both ears must be taken. Dr. Cor van der Lugt explains that in recording a print directly, “The first time the pressure applied has to be gentle, the second print has to be done with normal pressure and the third print is taken by applying much more pressure,” in case a gentle, medium, or heavy pressure print is not individually successful in capturing the entire ear print. In Conclusion, ear prints may be lifted, recognized by shape, size, and peculiarities of the ear, and identified with previously documented individuals. A criminal often presses his ear against a wall, window, or door during the crime. Because ear prints are common occurrences at a crime scene, and because ears are individual, unchanging anatomical structures (much like fingerprints) they are accurate ways of identifying suspects. Ear prints may be recorded like fingerprints and matched with a
For over a century fingerprints have been one of the most used tools of forensic science. Fingerprints have been used to identify criminals of small crimes
Footprints and Footwear are commonly undervalued at a crime scene due to lack of education or training of the investigator. The value from this type of evidence is actually invaluable and should not be over looked at the scene. Every criminal must enter and leave the scene which means that a print or impression will be left behind at the scene. Footprints and Footwear can actually give a massive amount of information of the suspect. The details that can arise from either piece preserved could be used to tie a suspect to the crime for a later conviction. Investigators must remember that every footprint, partial or full, has potential to provide information about the person, who left it at the crime scene such as, size, weight, stature,

The purpose of this experiment was to investigate a crime scene. Given an evidence bag a number of tests were performed in order to determine who the suspect was. The experiments included a simple fiber burn test, iodine fuming to develop a finger print, and thin-layer chromatography to determine ink similarities.
Bertillonage was a process of recording criminal’s body measurements to keep on file with photographs and other detailed information. This became vastly popular until fingerprinting was recognized as a more effective method. Once this was discovered he incorporated fingerprints for only the right hand in his processing. One obstacle that proved to be a problem with Bertillonage
The main provision in all cases is the avoidance of including fingerprints to evidence, or of ruining the ones already existing at the time. Once the crime scene has been carefully recorded and each of the evidence located have been annotated, then the process of gathering and analyzing can commence. The crime scene investigator will start by collecting the most delicate and easily prone to be lost evidence. Locating latent fingerprints at the crime scene requires use of techniques that makes it ideal for visibility. Investigators will use a several of methods to visualize the print, however it will depend on the surface that print is being lifted from. All non-movable and fixed items at a crime scene sustained to be handled on the scene using one of
Finger-marks are known as a small print that can be left on any surface, each finger-mark is unique to an individual. There are multiple types of finger-marks the three main ones are known as a Whorl, Arch and Loops. The finger-marks are always photographed before being collected at a crime scene, there are several different types of techniques that are used to be able to lift the prints. There are hinge lifts, rubber lifts and cellophane tape.
George Orwell’s 1984 was created to demonstrate the dangers that totalitarianism poses to the social order. A totalitarian regime establishes control through its degree of power. The novel is in a world of perpetual war, omnipresent government surveillance, and public manipulation dictated by a political system that persecutes individualism. In Oceania, freedoms and individuality are crushed under the power of the government. Orwell’s representation of a dystopia mirrors the perfect totalitarian state. Orwell glimpses into the future where The Party, the fictional government system, is unflawed in its universal control over society. Winston Smith, the novel’s protagonist, goes from an independent thinker to a shell of a man, who can only regurgitate
The most significant milestone in forensic science is the use of fingerprints in business transactions. People in accident Babylon used fingerprints because they are unique to every human being. The reason fingerprints are distinct to individuals is because they are formed when the bottom layer of the epidermis develops at the different rate than the rest of the skin, thus it buckles and tugs on the
There are three types of fingerprints that could be left at a crime scene. The three types are latent, patent, and plastic. Latent fingerprints are made from the oil and sweat on the surface of a person’s skin. This type of print is invisible by the naked eye and requires processing for visibility purposes. The process can be done using chemicals or powder. Patent fingerprints are made from blood, ink, dirt, or grease and they are visible by the naked eye. Plastic fingerprints are made when a person presses on wax, paint, or soap and they are visible by the naked eye. The three types of fingerprints help investigators discover who was at the crime scene which can possibly lead to the arrest of suspects.
Every single ridge has a row of sweat pores. When sweat seeps out of these pores, it runs over the ridges. Thus, when a finger, palm, or foot touches a surface, an impression is made which in technical terms is known as a latent print. However, when a print is collected from a police station directly from the source, this is known as an exemplar print (Haber and Haber, 2008; Creswell, 2015). The “science” of fingerprint analysis rests on three, recently, controversial assumptions: Firstly, the ridge patterns never change during the life of a person; secondly, no two individuals will have the same ridge patterns; lastly, the transferability of an impression of that uniqueness to another surface. (Gianelli, 2006). This allowed for fingerprint analysts to form a procedure which other experts around the world are invited to use, known as ACE-V.
Baby fingerprints can be captured for multiple reasons: preventing babies from being switched at hospitals or help to find missing children. Many parents have already captured their child’s fingerprints for child safety reasons, to have on hand in case of an
The very first murder case in Britain regarding bludgeoned husband and wife victims, Thomas and Anne Farrows, would have been impossible to solve if not for the fingerprint evidence that implicated the Stratton brothers. Millions of cases after involving fingerprints all relied on the analysis and identification to determine guilt or innocence. ("Fingerprint evidence is used to solve a British murder case") The significance of fingerprinting is undeniable; they can successfully prove that a criminal was present at the scene of the crime or help exonerate the innocent based on the scientific and legal establishment that fingerprints are
Every time somebody touches something, they leave behind a unique signature that forever links them to that object. This link is their fingerprints, which are unique to every person, for no two people have the same set, not even family members or identical twins. Palms and toes also leave prints behind, but these are far less commonly found during crime scene investigations. Therefore, fingerprints provide an identification process that is applicable to background checks, biometric security, mass disaster identification, and most importantly, crime scene investigations. Fingerprints are so differentiated because they are made up of distinct patterns of ridges and furrows on the fingers. The ridges are the “raised” portions of the prints, and the furrows are the “recessed” portions. This perceived uniqueness has led some people to falsely accept fingerprint analysis as absolute scientific fact. Although overall fingerprints are reliable, there are definitely situations where their accuracy can come into question.
As a white female, I am the opposite of a diverse minority in America, but that has never stopped me from observing and appreciating the diversity around me. My middle school student population was about a 70% minority makeup, and I loved it there. I never stopped learning new things from cultures I hadn't been introduced to in elementary school. High school is no different. I am currently attending an early college on the campus of the nation’s largest public HBCU. My class of 2017 is very small, and extremely diverse. The friends I made are from cultures all over the world: from Panama, Nigeria, Hungary, Vietnam, El Salvador, Pakistan, Germany, India, just to name a few. As the only white female in my grade, every friendship I made gave me
