Fingerprint recognition

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…

To know about phenomenon refraction you must learn the meaning of the word and how is does it apply to forensics science. Refraction is when the waves bend as they pass from one medium to another, when that happen, it cause the waves to have a change in their speed. When a series of waves create an angle traveling toward the new medium, one side will change speed before the other side, causing the waves to turn toward the slower side this is known as a phenomenon. Phenomenon is associated with…

The purpose of the previous study and results was to identify the possible perpetrator of the presented crime through blood analysis and match our forensic analysis with the characteristics and medical records of the missing person. In our blood analysis, we were given four samples of blood and the respective names of the suspects. In addition, Lowry police informed us that the second type of blood found, the one from the perpetrator, was O+. For this inquiry, our group hypothesized that based…

Forensic science?”, “How is it used?” Maybe this essay will answer all your questions. Forensic science is often confused with criminalistics, but they are different. Forensic Science is based on the evidence they find at the crime scene, like DNA, fingerprints, etc. Criminalistics is based upon these four types of evidence, testimony, direct evidence, circumstantial evidence, and real or physical evidence. “Testimony is information based upon a sworn eye witness. Direct evidence…

Zaiac says, “Fingerprint-based background checks bring serious problems,” I agree with Zaiac’s statement. The law system is never equal. The law enforcement is very biased and dishonest. There could be a lot of complications with the fingerprinting and keeping up with the…

You wouldn’t want anything to happen while loading and figuring our evidence. There are first a few important things that definitely have to be done at the crime scene. First they must always wear latex gloves, you wouldn’t want one of their fingerprints to get on any of the evidence before it even goes to the lab. They should always use clean containers to put the evidence into, you don’t want to contaminate any of the new evidence with old evidence. Label the items so that things do not…

After the advancement of tools became a major step in the Victorian era, the method of dissecting bodies for criminal work began to be explored. Sherlock was known for working with dead bodies and working with cadavers, yet he was not the first to adopt this method of crime work. Before Sherlock's method became known, Giovanni Battista Morgagni changed the way the idea of dissecting bodies for criminal work purposes would be looked at (Wagner, 4). Before Morgagni's idea came to be, the thought…

Police Department to give him two attic rooms where he conducted research and discoveries that became known throughout the world by forensic scientists and criminal investigators. After the Lyons laboratory was established, he developed the study of fingerprint pores and the impressions produced by these pores. Locard's exchange…

A vital tenet of forensic science is the exchange principle first proposed by Edmund Locard, which can be generally understood as the phrase “with contact between two items, there will be an exchange.” Every time there is a contact between individuals, environs and articles, there is an exchange of physical evidence, however small it may be. This aspect plays an indispensable role in crime scene investigations as it enables the detectives to establish links between the crime scenes, victims and…
