Fingerprint

evidence—some of which included multiple sets of latent fingerprints and a blood spatters—that could lead to a possible suspect or even the culprit responsible. Immediately, the forensic specialist begins to powder, lift, and collect the evidence. Considering the value of the individual evidence found—as D. P. Lyle stated in Forensic for Dummies was the “narrow down of evidence to a single, individual source,”—how great of an impact could those fingerprints and deoxyribonucleic acid filled blood…

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…

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…

crimes than ever before. Also the field has grown exponentially over the years. Forensic science majors study science and criminal justice and they learn how to analyze blood, DNA, and other evidence to use in a court of law. Blood spatter, fingerprints, and DNA are what forensic scientist use mostly to solve a lot of crimes that other detectives and investigators can't handle so forensic science is very important. In my second,third, and fourth paragraph I will be explaining what each of…

In a Chronological list of cases, Newbold stated that because of this case in “1911 The first conviction is achieved on the basis of fingerprints. The case involves Thomas Jennings, found guilty of murder in Cook County, Illinois” (1999). The case of People v. Jennings happened in 1911 after Clarence B. Hiller was murdered in his own home one night. Hiller and his family were all asleep in their home when it happened. It wasn’t until Hiller woke up and found that their gas light was no longer on…

When a finger comes into contact with a porous or non-porous surface, it deposits the dirt or oils present, remaining as a mark (Fingerprint Source Book, 2013). A latent mark is unique to the individual and is an affirmative source of identifying a potential suspect or witness. They also are invisible to the naked eye. Identifying a latent mark at varied crime scenes can be done using different developmental techniques such as wet powder suspensions (Dhall and Kapoor, 2016). These potential…

For example if a mom wants to figure out if her father is actually her father, she would have to get a DNA fingerprint and they will check in a lab and if it comes out positive it means it is his daughter. DNA can be used in many other ways. Many people deal with DNA every day of their lives and they don’t even realize it. the sequence of DNA is A,C,G,T,C, the way they make the dna fingerprints by first isolating the DNA and then you cut,size, and start sorting, the third step to make DNA is…

Latent fingermark being imperceptible to the unaided eye is the decisive form of physical evidence found on divergent surfaces at the scene of crime. It is decisive because of its perpetuality and uniqueness. The word ‘fingerprint’ is common in commonality but individual to a person. When a person grasp something, he left the traces of residues (secretions of glands) conforming impression of the ridges of the fingers. The fingermark residue is a complex matrix of secretions and xeno-materials.…

chemistry to the findings of crime. It includes firearm, forensic psychiatry, questioned document examination, criminal law, identification, photography as well as crime scene processing. They judge things like hair, body fluids, bullets, shoe prints, fingerprints, drugs and plant materials. Their work is not only bound to crimes against somebody, such as homicide, theft, or fraud. Food poisoning, environmental pollution, misuse of unsafe chemicals, and dangerous working conditions are also some…

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…
