Forensic Science Research Paper

“Forensic science has become in the early 21st century what the space race was in the 1960s- an accessible and inspiring (Gaensslen) into the world of science” (Gaensslen ix). This may be true but forensic has not always existed forever. Many people began hearing about forensic science during the 1990s when many of crime shows became popular. In actuality forensic science goes as far back as ancient China. Sculptors used fingerprints to identify their artwork from that of others. This may not be what forensics has evolved into but it had to begin somewhere. The first text reference of forensics first showed up in Hsi Duan Yu, which was published in about 700 CE (Hunter 18). It noted that many bodies have various characteristics that make them different. Many of the early forensic advances took place in the 1700 and 1800s. In 1784 the physical matching of evidence began. It was first used in the case of John Toms to link him and a piece of pistol wadding to a murder (Lotter). From then on forensics began to grow exponentially. “A major landmark in forensic science, the discovery that

Forensic Science Forensic science is a scientific method of gathering and examining evidence. Crimes are solved with examinations such as gathering fingerprints, palm prints, footprints, tooth bite prints, blood, hair and fiber samples (assampolice, par. 1). Handwriting and typewriting samples are also studied, including all ink, paper, and the arrangement and appearance of printed matter. Studying of the firing, flight, and effects of ammunition techniques are used to identify weapons as well as voice identification techniques are used to identify criminals (par. 3) Italian, Fortunatus Fidelis, was the first person to practice modern forensic medicine in 1598.

We did many tests, one of which was where we gathered up multiple footprints including the one found at the crime scene and analyzed and compared them. We also did a fingerprint test to determine

We predict that if the samples are identical then the suspect was the criminal. We think the samples from the shoe of the suspect do not match with the sample from the crime scene.

Behind every court case there’s a train of forensic science evidence and research. Forensic science is the application of scientific principles of criminal justice. In many court cases a forensic scientists is the one on the scene collecting finger prints, photos, blood samples and other evidence. Unfortunately one of the controversial issues in the forensic world is the evidence and its lack of verification of its reliability. In the field of forensics there are issues in finding proof in generating conclusion, fundamental knowledge to solve problems, and the whole false memory defense in the court. These issues can be solved in many ways like extensive research, preparation and training. These issues

Forensics has added so many areas to crime solving that every detail is analyzed now. Even photographs. Let’s face it, photographs now are a million times better than back in the 1800s when Mr. Ripper had his reign of terror.

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;

Footprint and footwear evidence is very valuable. A footprint is the impression that every individual leaves on a surface that has some sort of moisture, it can also be left on a dry surface if the footwear or feet are damp they walk on it. If footprints are undisturbed they can last on a surface from a small amount of time to a long period of time.

Friction ridge evidence has always been considered infallible in crime investigation and conviction of those involved. Traditionally, latent print examiners have presented identification testimony in courts with an explanation of identification or with a charted enlargement of matching and latent print. [1]

The first trial in the United States to use forensic anthropologist techniques was the Leutgert Sausage Trial in 1897. In this case a man who owned a sausage company was found with residual human skeletal remains in his vats at the sausage factory. George Dorsey, Harvard alum, identified the bones in the vat, and testified at trial. Although these techniques were not modern by any means, it paved a way for forensic anthropology in the US legal system.

First, let’s begin with where and when forensics is aid to have gotten its start. The basic sciences began to develop in the late 18th century, and many of the early developments in forensic sciences took place during the 19th century (Gaensslen & Larsen,

All different types of physical evidence are interesting and play a vital role on a case to prove the defendant's guilt. One of the different types of physical evidence I find the most interesting are the foot and tires impression that could connect a perpetrator to a crime. The impressive part of the shoe is that it could prove what size and type of shoes the perpetrator wore during the time of the crime. The tire print also

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime

Physical evidence collected at a crime scene provides much needed information for a criminal investigator to build his or her case. Since the inception of the Innocence Project in 1992, more than 300 wrongfully convicted people have been exonerated after DNA testing established that the crime for which he or she had been convicted was committed by another (Innocenceproject.org, n.d.). Advances in forensic science makes possible the means to individualize other items of evidence that point to the person or persons responsible for a crime. Dr. Edmond Locard formulated the principle that is the foundation of forensic science: Every interaction leaves a trace. A drop of sweat or a flaked off skin cell could be all that is needed to corroborate a defendant’s presence during the commission of a crime.

Fpositive impression and negative impression. Positive impressions are known as an impression that results in accumulating dirt underneath the sole of the shoes and then depositing on a clean surface. Negative impressions are known as impressions that are made by clean shoe stepping on a dirty surface, thus removing dust from the surface where the shoe sole made contact (1, 4). In figure 1, you can see the footwear impression on a hard surface and soft surface resulting from positive and negative impressions. The first area of comparison is the design on the outsole that is produced, but there are thousands of outsole designs that are being produced. The details on each sole vary from each other and each design has different sizes. Meaning, different types of shoes are made with a different style of an outsole and each size has its own outsole design, which gives further distinct characteristics to the outsole design even if the shoe is in the same size. The resulting physical differences in the size and shape qualities of the sole is of additional comparative usefulness in connecting or disassociating scene impressions with suspect’s footwear. In case, if a shoe has a plain outsole, then the physical size and shape is taken into account and can still associate the suspect by comparing it with the impression lifted off from the crime scene. In contrast, if a shoe’s outsole has a design, physical size and shape can be taken into account to compare the impression with the
