Latent Fingerprinting and its Reliability as Forensic Evidence

Introduction
The discovery and subsequent improvement in forensic science has been a road marred with many challenges. However, despite these challenges, its acceptance as a rudimentary source of evidence in the judicial system is fascinating. Nonetheless, there are copious number of skeptics who argue that the science is based on probability; thus does not fit to be termed as an actual science. (1) Among the source of their skepticism is in evidence collection. In this work, there is an exploration of fingerprint collection on diverse surfaces.

Ways of Collecting Fingerprint Evidence from different Surfaces

Fingerprints can be identified from several surfaces, which include the porous, non-porous, and semi-porous ...

The use of biometric evidence in executing criminal justice has gained reputation throughout the world as a result of rapid advancement in technology. In essence, biometric recognition entails the use of biometric equipment to recognize individuals through their biological characteristics (Sanders et al., 2010). Bio information of a person is captured and analyzed for use in identification. Some examples of bio information include fingerprint and signatures. A biometric evidence is the most popular and convincing method of confirming the identity of a person (Reedman, 2015). The criminal justice system uses different biometric characteristics to identify criminals depending on the ...

Introduction

The American criminal justice system relies on the knowledge and equipment of many sciences and skills. Forensic evidence has become one of the strongest weapons for the successful prosecution of the criminal offenders. Some scientific theories and tests are so widely accepted and verified that they are virtually beyond criticism. The theory that each person’s fingerprints are unique, for example, has universal acceptance.
Historians believe that the Chinese used thumbnails to sign important documents before the birth of Christ. But it was not until 1870s that a British civil servant in India used fingerprints to record persons on ...

Summary of the Case Against Mr. Didid

This report is for the evidentiary file of Mr. Isure Didit. The five contraband images previously discovered on Mr. Didit’s laptop were matched by using hash values by the National Center for Missing and Exploited Children (NCMEC) to those of known child pornographic images (previously tied to known underage victims) Because of this discovery, Mr. Didit’s company exercised its right to monitor employee activity at all times and to take company property back into its possession. Thus, we instigated an investigation into the contents of Mr. Didit’s office. In the office, the digital evidence was : ...

Automated Fingerprint Identification System (AFIS) refers to a computerized system used to store fingerprint images. Typically, investigators feed new print images into AFIS to identify the best matches. Accordingly, the identification process allows investigators to narrow their search parameters. Usually, AFIS technicians perform the final analyses of retrieved images to maintain accuracy. Prior to the computerization of such systems, the process of comparing fingerprint images was tedious and sometimes inaccurate. The development of AFIS, however, allowed technicians to perform comparisons within minutes and achieve a relatively higher accuracy of image identification.

Latent prints can be defined as the pretense of individual’s ridged skin. They are generally known as friction ridges or fingerprints. These impressions are regularly imperceptible to the exposed eye despite the fact that they are surrounding us and each one of us accidently leaves them everywhere. At the point when an investigator is dealing with a crime, other than taking a gander at the physical proof, one of the main things they do is check for fingerprints. This is an exceptionally sensitive process on the grounds that relying upon the surface a latent print can without much ...

Fingerprint analysis is the oldest and common form of forensic evidence and unique of each individual. There are two types of finger prints –patent and latent. Patent fingerprints are easily visible to the naked eye and are caused by inks, blood, oil or paint ("A Simplified Guide To Fingerprint Analysis", 2017). Latent ones are not visible to the naked eye and are caused by skin secretions like oil and sweat (Daluz, n.d.). There are various ways of experimenting the latent fingerprints depending on the surface, material, temperature and chemicals. Here we will study the effect of different temperatures (hot ...

In this presentation, I will be making a presentation to the court seeking an arrest warrant against one Damien Jones following the murder of Paul “Shorty” Alcorn. I have sufficient evidence to enable me to present a prima facie case against the said accused person. That evidence ranges from police reports regarding the homicide, police reports regarding the robbery with violence; we have forensic reports and also the analysis of the forensic reports. In the analysis of the forensic reports, we will be looking at the various pieces of evidence including documentary evidence. We also have the various property records of ...

It was on a cold January night when the local police were informed of a suspicious activity reported by the neighbors in a locality. An old woman possibly living all by herself had not been seen or heard of since several days, whereas the locals had reported her of being very active and outdoorsy. Yet since two days, she had not been seen outside her home, and when a neighbor visited her, he returned back without an answer even though he waited for several minutes. They tried her number, but she would not answer as well. The police were ...

A DNA profile is generated with the help of the DNA is that is left behind by the skin cells. This is known as the Touch DNA. Even though the samples that are used in this case are very small but the Touch DNA can be retrieved with the help of a technique that is launched recently and is known as the Polymerase Chain Reaction (PCR) which will take small samples of the DNA and make similar millions of copies within just two to three days . As the collection of fingerprints is a difficult task, and there is a ...

Processing Fingerprints

“A Simplified Guide to Fingerprint Analysis” lists three types of prints that can be lifted at a crime scene (2013). They are as follows: (Note: all information in this section comes from this article).
Soft surface prints. These 3-dimensional plastic prints are found in soap, wax, wet paint and fresh chalk.
Hard surface prints. The prints fall under two categories.

Patent Prints (Visible)

Found on smooth, rough, porous (paper, cloth, wood), and nonporous (metal, glass, plastic) surfaces.
Can be found in blood, dirt, paint and ink.
Collecting patent prints is done by high-resolution photography. To improve the quality of the ...

A porous item is a surface that contains openings that allow for the absorption of liquids to go through the material. One of the typical examples of porous materials is raw wood as it can absorb liquids or fingerprints oils especially if it is not varnished. Chemical development can be done through fingerprint processing of natural wood that is from a physical developer. Fingerprints can be developed through chemical processes of a silver based reagents that prints are produced, and they become gray colored (Trozzi 2001).
In a crime scene, you can get wood outdoors, and this can also ...

Is Password Security Becoming Obsolete?

Is Password Security Becoming Obsolete?
The use of passwords as entrance to secure sites is quickly becoming a thing of the past, as well it should, for a number of reasons. Passwords are generated by software programs and people to guard access to personal computers, websites, mobile telephones, and other types of technology. However, the users of technology are becoming more uncomfortable with the lack of security provided by passwords and with remembering all the passwords needed for such data as credit card numbers, health information, and bank accounts (Luukkonen, 2015). Advancing technology has provided users with the ability ...

Abstract

In the recent times, scientists in the discipline of artificial intelligence are confused which approach closely imitates the structure of a human brain. The best two approaches are bottom-up, or the top-down, and they comprise of both their advantages and disadvantages. The top-down approach has the capability to perform high-level tasks since it is programmed (Russell et.al 27). On the contrary, the bottom-up approach is capable of modeling the lower-level human functions such as motor control, image recognition, and learning capabilities. Each method operates perfectly where the other method is imperfect. Therefore, to establish the advantages and disadvantages of ...

What does it mean to be a "person," and "when" does personhood "begin? Herein lies the basis for much of the abortion controversy.
The very essence of being a person belongs to the definition of personhood, which cannot be narrowed down to a single definition. Here the aim is to explore the various definitions of Personhood and on the basis of these justify the often ethically debated concept of Abortion. On the basis of physical traits, as described by the Center for Health Ethics (2011), a physical human body of ‘homo sapiens’ is considered a Person. Therefore, the mere presence of a human body ...

Documentary: The Real CSI

The documentary is focused on the reliability of forensic science to arrest and convict defendants charged for particular offenses. However, some experts are of opinion that forensic science uses techniques that have not been validated scientifically such as the science of fingerprint analysis. It has been well-established in the law on evidence that fingerprints represent the highest standard of forensic science since “no two persons can have the same fingerprints”(Reagan, “The Truth About Forensics”). However, poor forensic analysis done by examiners can cause the conviction of an innocent man who is sentenced to suffer imprisonment for a crime he ...

In Brian Smart’s essay “A Case for Identity”, the main conclusion is that objects do have a form that is more than the sum of its parts, while John Perry finds in “The Problem of Personal Identity” that the human form is only a part of identity. A ship is an object that has no identity of its own beyond that human beings ascribe to it, since it has no conscious thoughts, memories or reflections of its own. In the case of a person, however, identity is more than simply body parts, fingerprints or physical appearances, but as far as science ...

Abstract

Actions taken at the beginning of a crime scene investigation can have far-reaching implications in the resolution of the crime, apprehension of the suspects and prosecution in the court of law. Meticulous and thorough investigation is key in ensuring that potential evidence is not destroyed or tampered with and witnesses overlooked. While many criminal investigation agencies employ a wide range of programs, techniques and equipment used in crime scene processing, the resources available and level of training vary from country to country. Apparently, the ability to investigate crimes has improved dramatically over the years with advances in information and ...

ABSTRACT

The Transport Security Administration (TSA) estimates that there are close to 1.8 million passengers passing through airports in the U.S. everyday. This makes airport security checks a vital part of security operations across the nation. The TSA oversees these operations under the directive of Homeland Security in collaboration with various airline companies to ensure optimal security for passengers and staff at airports. Several standardized security checks enhance security whist reducing crime rates in airports implemented by the TSA include use of Biometric Technology and Pre-Check programs. While these efforts are successful in reducing crime rates, there is little to show ...

The internet provides a platform where individuals have the ability of remaining anonymous trading insults, while other people publishes confessional memoirs and articles without the fear of being recognized. However, this identity less platform provides a perfect alibi where criminals engage in criminal activities. Therefore, law enforcers have been forced to adopt new technologies to find a solution to crimes committed off and online. For example, researchers have postulated that a detailed analysis and penetration of the internet contents on social media and various other platforms plays an imperative role in solving terrorists and murder plots. This is conducted through a revelation of the ...

The scenario depicts the crime of Burglary (House Breaking) which can generally be defined as the breaking and entering a house or dwelling or building or residence with the intent to commit a crime. However, the different Criminal Codes of the States of the United States of America have various variations of the definition of Burglary and/or Housebreaking. Sneaky Peat broke into Alison Collins’ house and left with a laptop, iPod and other things which perfectly fall within the definition of burglary or ...

The United States government should require all citizens to submit DNA fingerprints, regardless of whether or not they have committed a crime. By doing this, the United States government would be able to keep more detailed record of all its citizens. There are thousands of criminal investigations each year where there is evidence of finger prints, but there is no match on file to determine who they belong to. By requiring all citizens to have their fingerprints on file, these types of cases would be solved much easier. Finger printing all citizens may even reduce the crime rate in the ...
