Unit 4 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…

received high traffic. From a total of 40 different prints found in the numerous location, in the identification process and a result of 16 prints compared in detail between all of them, following the different patters loop, whorl and arch (Crime Scene Forensics, LLC, 2012.) In the identification process there was only one magnifying glass used in the study of the prints. The first step was to use the identification of the different patterns, after the identification and classification of the…

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.

While x-rays are regarded as accommodating tools to complement forensic investigations, there are also limitations present. CT imaging provides optimal views of anatomical structures with elaborate reconstructions to view the images in innumerable ways. The remarkable features of CT scanners are associated with expensive costs of the construction and maintenance of the scanner. Though the payoff is extraordinary, facilities would need a great amount of funding before the installation of a CT…

A coroner is someone who examines dead bodies and sees what caused that person to die. Some interesting things about the Grundy County Coroner, (John W. Callahan) is that he examines the fingerprints and x-rays of the dead body and he looks at the DNA records with the fingerprints and he takes all of this to the law agencies to see what they can do with it to see how they actually died. First, John Callahan when he works on 24 hours a day, 7 days a week getting calls at his office for Union…

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.…

condition also indicates survival of a serious pathological condition that was spreading through South China in the Middle Pleistocene period. (Proceedings of the National Academy of Sciences of the United States of America. Vol. 108 Issue 49). When forensic anthropologists are identifying any skeletal remains using X-Ray or CT machines, it is often times pretty easy to find areas of blunt or sharp force trauma and sickness because everything leaves a mark. Like I mentioned above, if the…
