Fingerprint recognition

Forensic evidence is evidence obtained using scientific methods including but not limited to, ballistics, blood analysis, and DNA testing. This evidence is extremely important and is used to establish the guilt or innocence of suspects. There are so many tiny parts that go into solving a case. When one thing during an investigation is done wrong, or not found a case can go unsolved very easily. Without the right amount of evidence it is hard to convict a suspect of the crime in question.…

CAREER JOURNAL: CRIME SCENE INVESTIGATOR Crime Scene Investigators gather and collect forensic evidence, such as hairs, fibers, and tissues, to establish their importances during criminal investigations. Crime Scene Investigators are generally forensic scientists or field examiners who have been trained and guided to gather evidence throughout criminal research. People who have pursued careers in this field of biomedical science hold a bachelor's degree in a forensic field, and a degree in…

Blood Stained Tee Shirt Collection of item: I would wear disposable latex gloves to packaged the blood stained tee shirt into a plastic or airtight container. I would store it in a cool location until it was delivered to the laboratory. Processing of item: 2. Handprint on car Collection of item: I would apply powder to the location of the handprint and then I would lift it with a broad piece of adhesive tape. I would place the tape on a properly labeled card that provides a good…

Nowadays, due to development of technology, our society have been highly advanced and this lead the diverse occupation so that people can work in different majors. In modern days, there are several new profession related to chemistry were created and it is even harder to find a job that have no any relation with chemistry. There are numerous vocation that have relationship between chemistry including pyrotechnic chemists, environmental chemists, nuclear chemists, crime scene investigation…

Forensics Question # 2: Briefly describe how the Automated Fingerprint Identification System (AFIS) creates a fingerprint image. What characteristics of the fingerprint does the AFIS record for comparison? With the advances of computer technology in U.S. Police agencies during the 20th century, it was only natural that what was once a labor intensive and cumbersome system, such as the filing and storage of individual fingerprint records, would become simplified by the implementation…

When it comes to finding fingerprints, it is best to look in numerous locations around the home. There were ten different fingerprints found in the search, to include complete and non-complete prints. Many different items were used for finding prints, for instance the oven, refrigerator, kitchen counter, toilet button, bathroom door, mirror, television, car door, computer, and the iron. Almost all of the prints were pulled from the house except for the car door. The car door prints were…

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…

A forensic anthropologist is trained in the study of human skeletal biology and typically use their training to identify deceased when skeletal remains are the only useful evidence. They determine whether the skeletal remains are for a human or nonhuman. They use their training to identify the sex of the individual based on the skeletal remains found. The forensic anthropologist can estimate the time of death and the cause of death when the remains are not suitable for examination by a…

Forensic chemistry is a type of chemistry that is found in association with the solving of crimes or murders. Forensic chemists analyze and examine things left at a murder or a crime scene such as blood, fingerprints, hair, or anything with traces of human DNA that could be linked to the individual who may have been responsible for the crime. Forensic chemists use science to bring many killers and criminals to justice. There are a few educational requirements needed to enter the field…

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.…
