Fingerprint

John Zarka Mr. Kirby Forensic Science March 22, 2016 Shoe Print The basic theory behind footwear analysis is that, much like fingerprints, shoes may leave behind either prints (referred to as "imprints") or impressions that can be examined by investigators. The type of evidence left behind depends largely on the type of surface traveled. For example, a shoe will leave an impression in loose sand, but on a hard surface like concrete or linoleum, it will leave an imprint. These imprints or…

Technology goes hand-in-hand with forensic science, and everyday there are advancements. Law enforcement officers and forensic technicians have many tools they can work with now, making it a bit easier to help them solve crimes. They have tools for fingerprint analysis, ballistics, DNA typing, and recently forensic phenotyping of simple physical traits such as human eye and hair color. The future of forensic science is bright; tools, gadgets and programs are ever evolving and forensic…

Eyewitness Testimony or Physical Evidence Which Should You Believe In some trials you may hear about physical evidence, and hear from eyewitnesses from the crime. While Physical evidence is evidence that is collected from the scene of the crime, or found on a victim. Physical evidence can be scientifically tested, and sometimes compared against a suspect. Witness testimony primarily relies on that witness's memory, and hopefully their attention of detail. If you are a jury member how can…

means that the temperature, pressure, and concentration must remain consistent throughout time. However, a chemical change is sometimes required in order to understand the substance better. For example, some chemicals may need to be introduced to fingerprints which may not be visible to the eye. When chemicals are added to it, it may aid in making it more visible for the technicians(Johll,…

The history and breakdown of the forensic science career is a very extensive one that has a lot of standstills for long periods of time, but with that comes very many breakthroughs. Forensic scientists have a very hard and very important job, and many people have no idea about the risks it takes to become one, or to determine one’s innocence in a court of law. 1. Dating all the way back to 2698 B.C, forensic science started, accidentally, by a man named Shen Nung. Shen had tasted a documented…

this article may have helped in the identification of Hyo Jun Jin because it is all about the rates of decompositions of bodies in different situations. Her body was heavily decomposed when it found which is why they were unable to get an accurate fingerprint from her so maybe this article would of helped the detectives by understanding how long she had been dead for (Nawrocka et al. 2016). Another article that I believe may be beneficial to the case is written by Maria Lombardi, Jennifer…

Indeed, this is essential to the foundation of all forensic labs (Dale and Becker 173). Forensic scientists use electrophoresis gel to prepare and differentiate fingerprints (Bertino 165). Which is then uploaded to the Combined DNA Index System (CODIS). Allowing access to registered crime lab officials to share and compare DNA profiles (Dale and Becker 176). Sharing this information aids police investigations as mitochondrial DNA can be extracted from fragments of bone and compared to maternal…

Criminalistics, while often called forensics, is actually a subdivision of forensic science that encompasses a wide variety of scientific disciplines, such as toxicology, anthropology, and odontology. The primary purpose of this field is to identify, gather, analyze, and interpret physical evidence found at a crime scene, as well as present it in court. The gathering and analyzing of evidence is paramount to forming a case, prosecuting the perpetrator, and convincing the judge and jury. Without…

of the trace and transfer evidence may be viable for matching depending on the care taken by evidence collection personnel, as well as forensic technicians, and if there is a match in the database. Some matches could be made years later when new fingerprints or DNA are entered into the database for comparison. DNA is the most trusted evidence in forensic history. Forensic serologists study chromosomes in the blood, saliva, or sweat that differ from each individual and can convict suspects and…

Forensic applies to courts or the judicial system, combine that with science and forensic science mean applying scientific methods and processes to solving crime. Forensic Science deals with the application of the knowledge and methodology of various disciplines of science to legal matters. It involves the use of multiple disciplines such as physics, chemistry, biology, computer science and engineering for evidence analysis. For instance, physics is used to understand the pattern of a blood…
