Sir Arthur Conan Doyle is perhaps one of the best-known authors in the world. If you are unfamiliar with him perhaps you 'll know his creations better. He was the original creator of Sherlock Holmes, a revolutionary detective who was far beyond his time and helped shaped modern forensics. The Sign of Four is a story takes place in India and while being an incredible story that gives much insight into the characters, looking at the story from a historical viewpoint gives us a view into the genus that is Sir Arthur Conan Doyle. The Sign of Four was written in 1890 a year after the bertillonage method was created and widely adopted. Fingerprinting wasn 't widely adopted until 1892 when it was used by Juan Vucetich to convict a woman who had …show more content…
Yet fingerprinting is Mr.Holmes prefered method of identification in The Sign of Four. Fingerprints were also used in the adventure of the Norwood Builder as well as in The Missing Years. In The Missing Years Mr.Holmes explains to Mr. Carvallo how he analyzed prints "In my work entitled Upon the Distinction and Classification of Human Finger and Thumb Prints I enumerate five main groups of characteristic details and other sub-classification by which fingerprints may be systematically classified and recorded." This is very similar to how we perform fingerprinting today by classifying them into patterns such as whirl, loop, tent and so on and so forth. The one predominant difference in today 's use of fingerprinting is the rule of twelve. This rule indicates in order for a match to be confirmed you must successfully identify twelve minutiae shared between the sample print and the print you are matching …show more content…
“If this paper remains blue, all is well. If it turns red, it means a man’s life.” He dipped it into the test-tube, and it flushed at once into a dull, dirty crimson.”
This wasn 't the only time the famed detective used toxicology, in one of Sir Arthur Conan Doyle 's for famous stories devil’s-foot root is entirely based upon the identification of a non deadly drug causing hallucinations. Some hypotheses believe the drug to be LSD do to similarities in effects it has on its users. The second reason some believe the mystery drug to be LSD is because LSD is created from a natural alkaloid it may be found in the fictional root that was being used to drug people.
In the classic Sherlock Holmes tale The Adventure Of The Dancing Men, a man and his wife have been shot in their study. The man has been killed by a bullet directly to the heart while the missus is in critical condition with a bullet lost within her
From the early days, with little literary reference material, to the current day, with substantially more, but still insufficient formation, the science of fingerprint identification has managed to maintain its credibility and usefulness. Although, academic institutions have yet to recognize the field as an applied science and include it in the curricula, which would provide directed research and literary reference, in libraries. Without this academic recognition, progress in the field of fingerprint is destined to be sluggish. Description of fingerprint identification as a forensic science’ or an ~app1ied science’ in no way implies that is not a reliable science. Fingerprint identification, correctly understood and applied, is just as scientifically valid and reliable as any other science and, indeed, more accurate than many. The fingerprint expert applies knowledge gained through training and experience to reach a conclusion. The many uses of fingerprint identification range from criminal investigation to non-criminal matters such as deceased, missing persons and disaster victim identification. Fingerprint identification has been used in the court systems for many years. Yet there are those who that still try to challenge fingerprint science and the experts in the court of law by a Daubert Hearing. In this paper, Daubert Hearing is define and detail outing background of the cases, the Government preparation, the Testimony from both sides, the judge’s verdict and finally, Mitchell’s second trial on this case.
The acceptance of fingerprint identification in the judicial system as scientific evidence has become like expert testimony. Advances in image processing have impacted how fingerprints can be lifted without being destroyed, which has led to fingerprint evidence becoming the silent testimony leading to more conventions. In the case of the United States v. Byron C. Mitchell Criminal Action No. 96-00407, fingerprints found in the car were the scientific evidence which identified Mitchell as a participant in an armored car robbery (Appellant Counsel for Appellee, 2003).

Fingerprints were reported as unique in 1880 by a scientist called Henry Fauld’s in an article published in Nature, and in the paper,
In 1893, Francis Galton introduced a remarkable new way to identify people ("Fingerprinting" pg 1 par 3). His observation that each individual has a unique set of fingerprints revolutionized the world of forensics. Soon, all investigators had adapted the idea to use fingerprints as a form of identification. Unfortunately, over the course of the past century, criminals have adapted to this technique and seldom leave their incriminating marks at the crime scene. Forensics specialists were in need of a new way to identify criminals, and DNA provided the answer. When it comes to genetic material, it is virtually impossible for a criminal to leave a crime scene "clean." Whether it is a hair, flakes of skin, or a fragment of fingernail, if it contains genetic material then it has potential to incriminate. However, there are still concerns regarding DNA fingerprinting. What are the implications of using these tests in a courtroom scenario? What happens when DNA tests go awry? It is debatable whether or not DNA fingerprinting has a place in America's court systems.
Having the ability to identify types of prints and surfaces, and the corresponding techniques to develop the prints, has helped crime scene investigators identify criminals and victims of scenes, and aided in the prosecution of defendants in the criminal justice system. Although the history and techniques go far beyond what was discussed in these few pages, it is important as a law enforcement officer or investigator to understand the very basics of how fingerprint identification began, and the simple techniques used to develop them today.
There was a multitude of evidence collected by the detective in the movie: photographs, objects left behind like tools and bones, weapons, restraining devices, and newspaper clips and other things. In one scene the killer takes a man and ties him to a poll in an abandon area. He leaves wooden planks down the victim. He cuts him just enough to allow for the rats to pick up the scent of the blood. Sometime later the rats get to him, and tear him to parts. By the time Amelia gets to the victim he is gone. The only thing left for her is to retrieve the evidence left at the scene. One method that she used to capture this evidence is fingerprints; eventually taken by other investigators. There was a fingerprint left behind which they then checked the box for prints. She was trying to see if the killer finally made a fatal mistake in his crusade of murders, but sadly he had cut the finger off of another man. They found the person by what seems to be the IAFIS program, which was established and used by the FBI and used by many states. A fingerprint is an impression left by the friction ridges of a human finger. AFIS is a biometric identification methodology, and there are many of them. When you take one’s Fingerprints and upload them to a national database for the FBI, this is called IAFIS; the name is given to once specific AFIS, by the FBI. This is a national fingerprint and criminal history program. Fingerprinting is used in criminal investigation and other cases, like fraud prevention. A theory behind fingerprints is how our fingerprints begin to have our own characteristics. The theory of relativity in fingerprints, and it says that we inherit some characteristics of our parent’s fingerprints. We may get their fingerprint type, but our own unique characteristics, like ridge endings, bridges, etc. It could be used to help figure out
While hallucinogenic drugs have been used for centuries, it was not until the discovery by Western society of their mind-altering properties (Hofmann 1959; Stoll 1947; Delgado, Pedro L; Moreno, Francisco A) that these compounds began to be more widely used for treatment of mental disorders (see Abraham, Aldridge & Gogia 1996; Strassman 1995; Neill 1987; McGlothlin & Arnold 1971; Freedman 1968; Delgado, Pedro L; Moreno, Francisco A). Hallucinates are derived from plants or the fungus that grows on plants, the first recorded hallucination was a tossup between mental issues that were then used for a political push or the ergotamine during the Salem witch trails in 1962, far after that Albert Hofmann became the creator of LSD from ergotamine a chemical from the fungus ergot, in Switzerland 1938. From that time LSD has played a part in history, studies have shown that much has changed in the half-century since LSD was first used by psychiatrists and then found widespread recreational use in the 1960's and 70's. Modern psychiatry has embraced drugs that affect the same brain molecules that are tweaked by hallucinogens (Blakeslee,
The term forensic toxicology is defined as examination of all aspects of toxicity that may have legal implications (James & Nordby, 2009 p. 61). In the past, poisoning was one of the most popular forms of murder. There are countless natural substances in the world that when ingested into the body in high doses, can become lethal to the human body. What made this form of murder so famous is that most poisons mimic common medical diseases, leading physicians to believe a victim died of natural causes (Ramsland, n.d.). Aside from murder, this forensic discipline is also essential for determining accidental deaths and suicides.
Thesis Statement: In this speech I am going to explain how forensic teams use fingerprints to identify individuals.
The T.V Show no doubt is a great show based in London and is a modern adaption of the books by Arthur Conan Doyle. Though the T.V Show does not have a certain episode for Sign of the Four yet it has many differences in Sherlock’s methods of detection and his personality so it has definitely earned its spot in this book. The tv show was not meant to be related to the books so that all people could enjoy it. This is ironic since many small details are in the show that only the true readers of the book can understand.
Erika Dyck provides the reader and interesting view of early historical psychological research on LSD, lysergic acid diethyl-amide. This book is composed of Dyck’s scientific interpretation and dissection of earlier psychedelic psychiatry research by Humphry Osmond, and Abraham Hoffer. A Swiss biochemist named Albert Hofmann dissolved a minimal amount of d-lysergic acid diethyl-amide in a glass of water and digested this new synthetic drug in April 1943. Three hours later he begins to feel dizzy and his vision was distorted. Hofmann recollects this as a surreal journey as if what he saw was created by the famous paintings of Salvador Dali unexplained carnivalesque or at some moments even nightmarish hallucinations. The drug began gaining support from pharmaceutical companies as something that can possibly be beneficial for future scientific study. Saskatchewan soon became one of the epicenters harvesting break through biochemical innovation and experimentation with LSD from the 1950s to 1960s.
Fingerprint usage dates back to the 1800s. Sir William Herschel used the prints as signatures on civil contracts, before they were found useful towards crimes (History of Fingerprints Timeline, 2012). A British surgeon, Dr. Henry Faulds, wrote about using fingerprints for personal identification. He first looked at prints on clay pottery and studied the ridges and patterns that they had made in the clay. In 1891, Juan Vucetich suggested to start fingerprinting criminals to keep the prints on record. The following year, Vucetich identified a print from a woman who killed her two sons. Investigators found her print and were able to correctly match her identity. Charles Darwin’s cousin, Sir Francis Galton, wrote and published the first book about fingerprints. He wrote about how every individual has a unique print by the certain traits of each fingerprint (History of Fingerprints, 2012). The popularity of fingerprints grew greatly in the United States in the early 1900s. Police departments and the FBI began to use the...
The three different main types of fingerprints are Loops, Arches, and Whorls (Jackson 1). Henry Faulds is known as the Father of Fingerprints and developing fingerprints (Jackson 1). His discovery of fingerprints has made a huge impact not only in his time but, in Modern Crime Scene Investigation (Jackson 1). Without fingerprinting, it would be very difficult to convict criminals of crimes and very hard to try to process information. Crime Scene Investigators make a huge impact in Forensic Science. We need CSI workers, without them people could only imagine what crime would be like not only in our community, but in our
Forensic toxicologists have faced numerous challenges throughout the 1800’s and are still facing some of these challenges today. In Gettler’s and Norris’s time of being head of forensics in New York, they faced problems within toxicology study, and some out of toxicology. One of their main problems was metabolizing a poison and determining the lethal dose.
