Evaluation Of Emerging Screening Technologies For The On-Site Detection And Identification Of Methamphetamine And Its Precursors In Simulated Clandestine Lab Operations, Alexis Nicole Wilcox

Graduate Theses, Dissertations, and Problem Reports (ETD)

Stimulant drugs comprise one of the top drug categories abused in the United States. Due to its accessibility, low price, and manufacturing simplicity, methamphetamine is frequently placed within the top 10 seized drugs in the country. As of March 2023, methamphetamine is the most seized controlled substance in the United States, with 34,291 kg. In 2022, the United States seized over 79,000 kg of methamphetamine. One reason for the proliferation of methamphetamine is related to the production itself, which does not require large warehouses but can be manufactured in houses using relatively accessible materials and small containers. When a clandestine …

Footwear Image Quality Classification: Using Subjective Assessments And Objective Image Metrics To Predict Impression Quality, En-Tni Lin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Shoeprints deposited during the commission of a crime vary in quality as a function of numerous factors, such as substrates, media, and the specific physical activities carried out by perpetrators. This variability in impression quality impacts the amount of information available from questioned crime scene impressions, and therefore an examiner's confidence in providing opinions of source attribution. In response, this research attempted to characterize footwear impression quality based on image sharpness, contrast, entropy, homogeneity, noise, quantity of information, and complexity, and to integrate these hand-engineered feature descriptions with subjective opinions of impression quality.

The methodology followed a five-pronged approach. First, …

Evaluating The Degradation Relationship Between Latent Print Impressions And Touch Dna Under Varying Environmental Conditions, Katrina M. Rupert B.S.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Latent prints have been processed as a source of touch DNA evidence in the hopes of attaining partial or even full DNA profiles. However, the relationship between the latent quality and the DNA quality has not yet been fully explored, resulting in gaps in understanding how the two are connected. A common source of touch DNA is from latent print evidence, which is typically processed and photographed at a scene, and subsequently processed for DNA in the laboratory. However, there is skepticism in the forensic community around touch DNA as laboratory procedures are often manipulated beyond standard operating procedures to …

Strengthening The Interpretation Of Glass And Paint Evidence Through The Study Of Random Frequency Of Occurrence And Analytical Information, Lauryn C. Alexander

Graduate Theses, Dissertations, and Problem Reports (ETD)

Glass and paint particles are frequently discovered at crime scenes as valuable trace evidence. Often, these fragments are transferred from a crime scene to a victim or person-of-interest, and can subsequently be evaluated, analyzed, and classified according to their physical and optical measurements, and chemical properties, each of which can provide important information to the analyst to assist in the determining if a recovered particle is distinguishable or indistinguishable from a known source. Moreover, these minute materials can provide information about how the events took place, leading to the reconstruction of crime scenes and the identification of valuable clues for …

Feature Extraction Of Footwear Impression Images For Quality Assessment, Alexandra Hill

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forensic footwear impression analysis is a valuable tool in criminal investigations. Extracting useful features from images of footwear impressions is a critical step in this process. However, the quality of these images can vary widely, making feature extraction challenging. In order to give a quality assessment rating to a footwear impression image, the image should first be analyzed to extract features from the impression. In this paper, we present a method to extract features from a 2D grayscale footwear impression image.

An Assessment Of The Forensic Aspects Of Genetic Genealogy, Sarah Hester

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forensic genetic genealogy has grown in both popularity and controversy in recent years. The genetic information comes from large numbers of single nucleotide polymorphism (SNP) markers. Polymorphism variations can be traced through familial lineage, determining how closely individuals are related to each other based on the similarities and differences in SNPs within their DNA. Polymorphisms account for approximately 85% of human variation. Genealogy and ancestry determination companies trace the lineage of a person back through multiple generations using polymorphisms. As more individuals submit their DNA for analysis the genealogical profile databases continue to grow in size. Law enforcement uses genealogical …

The Rise Of Terrorism In Africa And What It Means For U.S. Policymakers, Bridget Mary Hughes

Master's Theses

This thesis utilizes three case studies to measure the rise of terrorism in Africa. This qualitative data leads the reader to one ultimate question: what does the rise in terrorism in Africa mean for the United States (U.S.) and U.S. policymakers, National Security academia, students in National Security, if anything at all? The answer is: if civilian and military compounds are being targeted by these violent extremists, as these three case studies demonstrate, it is my recommendation that U.S. policymakers cease sending troops to the African theater and, instead, allocate funding to the citizens and nonprofits of the countries whom …

Kerberoasting: Case Studies Of An Attack On A Cryptographic Authentication Technology, D Demers, Hannarae Lee

International Journal of Cybersecurity Intelligence & Cybercrime

Kerberoasting, an attack vector aimed at the Kerberos authentication protocol, can be used as part of an adversary’s attack arsenal. Kerberos is a type of network authentication protocol that allows a client and server to conduct a mutual verification before providing the requested resource to the client. A successful Kerberoasting attack allows an adversary to leverage the architectural limitations of Kerberos, providing access to user password hashes that can be subject to offline cracking. A cracked user password could give a bad actor the ability to maintain persistence, move laterally, or escalate privileges in a system. Persistence or movement within …

Method Optimization For The Determination Of Cannabinoids In Blood By Liquid Chromatography Tandem Mass Spectrometry (Lc-Ms/Ms), Kevin D. Carrera

Student Theses

Delta-9-tetrahydrocannabinol (THC) continues to be one of the most popular drugs in the USA. Along with THC, other cannabinoids such as cannabidiol (CBD), are on the rise due to an increase in medicinal usage as well as the passage of different legislations removing these products from their current schedule I status. Thus, an urgency exists to develop robust and sensitive analytical methods to determine cannabinoids, especially THC, CBD and metabolites, in biological samples.

Csi Effect: Exploring Impact Among Mississippi Lawyers, Jennie Odom

Honors Theses

The “CSI Effect” suggests that a growing number of jurors often have unrealistic expectations concerning the amount of forensic evidence which should be reasonably presented to convict an alleged criminal, and this misconception arises from watching heavily dramatized crime shows such as the CSI franchise. While many scholars have examined the CSI Effect, one critical perspective is often missing from the existing literature, that of the lawyers. Therefore, this project worked to explore the perspectives of both defense attorneys and prosecutors. Personal interviews were conducted to gain insight and perspective regarding the CSI Effect, whether these perspectives had impacted the …

Examination Of Kastle-Meyer’S Limit Of Detection And Cross Reactivity, Djonnique M. Devone

Forensic Science Master's Projects

Forensic Serology is a branch of forensic science that deals with the identification of certain trace evidence. Blood is the most commonly recovered and most important piece of evidence analyzed and used in criminal investigations. As evidence blood holds significance in criminal investigations because it can link a crime to an individual or exclude their involvement. Serology and DNA analysis are often aligned, because the same evidence item is often analyzed by both sections. During a criminal investigation it is important for to identifying the type of biological material or trace evidence found. The possible identification of bodily fluids can …

A Comparison Of Methods Used For The Elimination Of Organics From Soil Prior To Analysis By Ftir-Atr And Sem-Eds, Argeliz Pomales

Student Theses

This project suggests improvements to the treatment methods utilized for the sample preparation and evaluation of minerals in soil samples encountered in forensic science casework and research. The evaluation of pre-treated and post-treated soil samples were performed using Fourier-Transform Infrared Spectroscopy with Attenuated Total Reflection (FTIR-ATR) and Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). Because soil samples contain a significant amount of organic matter and water which interfere with examination of these minerals while using these instruments, pretreatment methods are necessary to isolate the mineral fraction for examination and analysis.

Soil samples were first sieved with various size stainless steel mesh …
