Child Pornography: A Growing Threat For Forensic Science In The Digital Age, Nadia Palomares

Themis: Research Journal of Justice Studies and Forensic Science

In the United States, child pornography is any visual portrayal of people under the age of eighteen in sexually explicit circumstances. Child pornography can be found in multiple forms. With each advancement in visual technology, there is a new form in which sexual content, including child pornography, can be depicted. Photographs, films, videos, and live streaming are all popular modern forms, while artwork and the written word were popular forms before the invention of the camera in 1816. Unfortunately, the rate of these advancements in technology has far surpassed the rate of those in forensics. The use of outdated techniques …

The Use Of Microbiome Sequencing To Identify Individuals In Forensic Science, Sophia Konieczny

Themis: Research Journal of Justice Studies and Forensic Science

The Human Genome Project's (HGP) completion in 2003 laid the groundwork for further research into the human body. This paved the way for microbiome sequencing, revealing the diverse microbial communities within the human body. These advancements led to the emergence of microbial forensics, leveraging Next Generation Sequencing (NGS) technologies like Amplicon sequencing and shotgun metagenomics for individual identification. Unlike traditional genetic profiling, microbiome analysis provides insights beyond genetic profiling, offering information about an individual's lifestyle and environment. Microbial communities on the skin's surface and objects can serve as trace evidence, aiding in suspect identification and investigative leads. Despite its promise, …

Recovery Of Nuclear Dna From Skeletal Remains Decomposed In Freshwater, Zoe L. Sikon

Master's Theses

This research compared freshwater and dry decomposition environments and their impact on DNA recovery from Sus scrofa domesticus(domestic pig) femora over a 3-month period. Prior to decomposition, initial cuttings were taken from "fresh" bone samples. Cuttings were then collected at 3-week intervals from waterlogged and dry bone samples. All samples were extracted using the vendor recommended protocol for the Applied Biosystems PrepFiler BTA extraction kit and an updated version of the same protocol, that substitutes Proteinase K with additional Dithiothreitol (DTT) (Thermo Fisher Scientific, 2012.). DNA quantitation was performed using pig-specific custom primer sets, with the QuantStudio 5 Real-Time …

The Application Of Particle-Correlated Raman Spectroscopic Analysis Of Soils To Mock Casework Scenarios, Sam Gong

Master's Theses

Soil is a continuous material, reaching across geological bodies, and is distinctly variable and differentiable based on aspects such as geographic location, seasonal factors, and human interference. In combination with its highly transferable nature, the complexity of soil makes it valuable material for forensic trace evidence and object-to-scene association. The development of forensic soil analysis is currently focused on mineralogy. Raman spectroscopy is a chemical technique that has previously been studied for mineralogy uses. Additionally, Raman spectroscopy has been researched for use in other fields of forensic science as well. As such, it is possible to use Raman spectroscopy for …

Effects Of Ethanol On Gaba Transaminase, Mary Corrigan

Master's Theses

Ethanol is the primary active ingredient in alcoholic beverages, and functions in the body as a central nervous system (CNS) depressant. The overt effects ethanol has on the body, e.g. diminished cognitive ability, loss of motor control, slurred speech, impaired balance, etc., are well documented. While the behavioral consequences of consumption are well understood, how ethanol actually functions on a mechanistic level to elicit those effects has yet to be satisfactorily elucidated.

The structural homology between ethanol and the C3 and C4 carbons of gamma-hydroxybutyric acid (GABA), the major inhibitory neurotransmitter in the mature CNS, has led us to hypothesize …

Determination Of Common Drugs Of Abuse And Metabolites In Oral Fluid: Comparison Of Different Extraction Procedures, Melissa Koffer

Student Theses

Oral fluid has been gaining importance in forensic and clinical toxicology for many different drug testing scenarios. Oral fluid is composed of saliva, along with gingival fluid, bacteria, and food residues. Drug testing using oral fluid has many advantages over other matrices (blood, urine) such as the non-invasive collection, reduced risk of tampering, and shorter detection windows which show recent drug use. The purpose of this study was to develop an analytical method for the determination of 19 drugs of abuse and metabolites in oral fluid by liquid chromatography tandem mass spectrometry (LC-MS/MS) and compare three different extraction methods: liquid-liquid …

The Detection Of Blood And The Recovery Of Dna From Heat-Damaged Surfaces, Teresa A. Distefano

Master's Theses

When investigating a scene exposed to high temperatures and long burn times, investigators should consider that recoverable blood could be linked to a source and give important profile information after DNA analysis. By locating blood with presumptive and confirmatory reagents, even after exposure to damaging conditions, investigators can attempt not only to confirm that blood was present but also to determine the DNA profile of the blood. Experimenting with the different burn times and temperatures in which blood is still detectable can be followed with DNA analysis, which will show whether the blood is viable after exposure to these damaging …

Adults Matter Too: An Examination Of State Adult Missing Persons Policies And Procedures To Implement A Best Practices Handbook, Hunter Smith

Honors Theses

The most recent estimates put the number of active missing person records at 97,127. Over the past eight years, child active records have decreased by 2,530, while adult active records have increased by 14,696. While there is no clear explanation for this trend, a common theory is that there are multiple federal and state laws requiring the entry of missing people under the age of 2; however, very few, if any, extend to adults. Additionally, there is a lack of standardization across available policies and procedures for where these cases should be reported, the time frame for doing so, and …

How Gender Affirming Care Affects The Current Sex Estimation Standards In Forensic Anthropology: A Preliminary Study, Dakota Taylor

Department of Anthropology: Theses and Student Research

Current sex estimation standards in forensic anthropology are based on individuals whose gender matches their biological/osteological sex, also known as Cisgendered individuals. Recently, transgender individuals have started to become more common in the forensic context due to the increase in hate crimes and violence. This research builds upon past research done on how facial feminization surgery can affect both visual and metric methods, where it was found that forensic anthropologists should rely on the visual methods if they suspect someone to be transgender due to it being more accurate and being able to clearly state the scars left on the …

Williams (J.A.W.) Documented Human Skeletal Collection at Western Carolina University in Cullowhee, NC (USA). Morphoscopic traits are nonmetric traits, visually identified using the knowledge of osteology. The study was performed to study variation of the vertebral column, specifically focusing on morphoscopic traits of the thoracic and lumbar vertebrae. The focus of this research is centralized on the presence of numerical variations in the vertebral column such as eleven …

The Osteobiography Of Human Remains From The Seaview And Indian Town Trail Archaeological Sites, Maggie M. Klemm

Department of Anthropology: Theses and Student Research

Extensive site surveys and excavations on the Island of Barbuda led by Sophia Perdikaris have identified over 62 sites spanning from the Archaic time period to Historic times. Over the last 18 years, these multidisciplinary teams have focused on mapping all sites and performing rescue excavations on sites threatened by sea level rise, erosion or development. Two such sites are the Saladoid site of Seaview (BA016) and the Troumassoid site of Indian Town Trail (BA01). The dunes surrounding the site of Seaview receive the brunt of storms and hurricanes. In 1998 hurricane Georges exposed skeletal material now part of the …

A Manual On The Planning And Integration Of Archaeological Methods In To Outdoor Forensic Search Investigations, Jonathan Robert Garcia

Department of Anthropology: Theses and Student Research

As archaeology and its applications into forensic contexts develop into the growing discipline of forensic archaeology, an increasing amount of literature has resulted stemming from research on the integration of common archaeological methods. However, much of this literature is intended for professional archaeologists or forensic anthropologists who are well experienced in their respective disciplines. Emerging literature generally does not consider those who leads efforts at forensic scenes in the outdoors such as law enforcement officers who often lack a background in archaeology or forensic anthropology. This thesis seeks to resolve this dilemma by creating a new and accessible manual. The …

Influences Of Social Media, Samuel Whatley Ii

Helm's School of Government Conference - 2021-2024

The Internet is a double-edged sword because it provides easy access to information of both good and bad intentions. Censorship justifications under whoever deems something misinformation, provide little oversight on being a neutral public forum. For instance, the influence of elections by not covering a story and censoring opposing views does not promote the notion of being a neutral public forum. Artificial intelligence being applied to many technological applications have fueled the censorship machine. In some instances, artificial intelligence can generate stories to media sites (i.e., ChatGPT) with no verification of the details. From science fiction to science reality, taking …

It involves the uploading of DNA found at a crime scene to genealogy databases to narrow down the suspect pool. The research question for this study is: Is law enforcement’s use of investigative genetic genealogy ethical? I conducted ten interviews with individuals who had a background in the Criminal Justice field, the legal field, the forensics field, and the field of genealogy to see their opinions on this topic. A majority of the participants in this study stated that they believe that law enforcement should be …

Understandings Of Vulnerability And Social Determinants Of Health In Forensic And Expert Social Anthropology: A Scoping Review, James W. W. Rose, David M. Tran

The Qualitative Report

Forensic and expert social anthropology (FESA) is a branch of social anthropology that specialises in the provision of evidence to legal-administrative processes, which are overseen by courts and other legally empowered bodies, and which give regard to the social cultures of legally and administratively involved individuals and communities (LAIICs). Despite a preoccupation with political advocacy in the broader philosophy of social anthropology, FESA literature does not typically give regard to LAIIC vulnerability defined qualitatively in terms of social determinants of health, including physical, mental, and social well-being. This paper presents findings from a JBI/PRISMA-ScR scoping review of n=1,674 texts, identifying …

Bone Traces And Modifications From Feeding By Dermestes Maculatus, B. V. Adams, Leon G. Higley

School of Natural Resources: Faculty Publications

That Dermestes maculatus feeding can leave marks on bones is established in the literature - that D. maculatus routinely mark bones is not. Our results here, exposing fleshed bones to D. maculatus adults and immatures for almost two months after complete tissue removal, indicate that under natural conditions D. maculatus do not feed on bones. The key issue seems to be the ability of D. maculatus to seek new food sources versus being confined (and eventually starving) on bones. In a natural setting, once a food supply is exhausted, D. maculatus would seek new food …
