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 …

The Role Of Investigative Genetic Genealogy In The Field Of Criminal Justice, Chloe Haas

Honors Projects

Investigative genetic genealogy is an investigative method used by law enforcement to solve crimes. 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 …

Validating Machine And Human Decision-Making In Forensic Fire Debris Analysis, Frances A. Whitehead

Graduate Thesis and Dissertation 2023-2024

This work presents a background on the chemical complexity of fire debris analysis, including an ever-present matrix of pyrolysis products as the catalyst that led to the creation of the National Center for Forensic Science's Fire Debris Database. A selection of these 1,000+ casework-relevant ground truth samples was used to create two newly proposed analyst workflows to connect the current method of categorical reporting with evaluative reporting practices reflective of the strength of the evidence. Both workflows use linear sequential unmasking to help mitigate bias, a discrete scoring system for quantification of the analysis, and receiver operating characteristic (ROC) curves …

Forensic Archaeology Protocols For Wildfires And Fire Related Scenes, Erik Schulz

Nebraska Anthropologist

Forensic Archaeology Protocols for Wildfires and Fire-Related Scenes

Forensic archaeology is a relatively new area of study and focuses on the medical legal aspects of archaeology. This paper will focus on how forensic archaeology should be used for wildfire and other fire-related fatalities or investigations, what happens to bone when exposed to heat, what protocols should be in place and how an excavation should look, and finally the challenges of fire-related investigations. This report will focus on the larger scale of the investigation and will be using several sources from different wildfire and fire fatality reports.

Inter- And Intra-Observer Error In Forensic Anthropology: Based Upon Langley Et Al. 2016 Data Collection Procedures For Forensic Skeletal Material 2.0 For The Cranium And Femur, Maggie M. Klemm, Dakota L. Taylor

Nebraska Anthropologist

Following the Daubert v. Merrell Dow Pharmaceuticals (1993) ruling three decades ago, guidelines were established for determining the reliability and validity of expert testimony in court. These guidelines include considerations of whether the theory and methodologies employed have been tested, the establishment of potential or known error rates, and the existence and maintenance of the standards (Christensen, 2004). Testifying in court as an expert witness has become a critical role as a forensic anthropologist. As such, the methodologies, techniques, and standards utilized by forensic anthropologists must be carefully considered and adhere to the Daubert guidelines within the court system. One …

Fat And Water Content Effects Of Three Food Substrates (Ground Veal, Ground Beef, And Beef Liver) On Lucilia Sericata (Diptera: Calliphoridae) Development And Mortality, Nicole Dailey

Master of Science in Forensic Science Directed Research Projects

Although temperature has been identified as the most important catalyst affecting blow fly larval development, other variables encountered by these species, such as the fat and moisture content of the food source, may have an impact on accurate estimations of the PMImin in forensic investigations. Thus, body composition differences between human carrion, such as variations in body fat and water percentages between younger and older individuals, or heavier persons, could affect blow fly developmental rates, and in turn cause over or under estimations of the PMImin. In this study, the weight, length, and development times of Lucilia sericata third instar …

A Comparative Analysis Of Swabbing Solutions For Sexual Assault Evidence: Direct Impact On Spermatozoa And Dna Recovery, Olivia Q. Kassie

Master of Science in Forensic Science Directed Research Projects

Forensic laboratories struggle with a backlog of sexual assault cases, prompting the need for effective techniques to develop consistent protocols and address scientific gaps. Challenges in recovering optimal DNA from assault evidence stem from factors like collection timing and sampling variables. Variations in lab protocols can lead to differences in DNA yields and profile success. This was observed in a state lab when protocols were developed allowing the use of acetone to swab sexual assault evidence. The use of acetone originated due to their case-routing protocols in multi-section cases involving latent fingerprints. While not necessary for sexual assault and porous …

Evaluation Of Charcoal Strip Extraction Efficiency Under Varying Substrate Conditions, Abby Wester

Master of Science in Forensic Science Directed Research Projects

The ability of a forensic examiner to identify the presence of ignitable liquids (ILs) in fire debris collected from the area of origin of a fire is an essential component for determining intent in fire investigations. However, this relies on an effective extraction method that provides a complete picture of what is present in the debris. In this study, eight substrate materials underwent three different treatments: a low-volume of substrate that was unburned, a low-volume of substrate that was burned, and a high-volume of substrate that was unburned. Each sample was spiked with a 1:1 mixture of gasoline and diesel …

Discrimination Of Blue Denim Fibers Utilizing Physical Characteristics, Optical Properties, Fluorescence Microscopy, Ultraviolet-Visible Microspectrophotometry, And Microchemical Testing, Elkin Howard

Master of Science in Forensic Science Directed Research Projects

Cotton, the most common natural fiber, has numerous uses in the textile industry. This fiber type is ubiquitous in forensic casework due to its prevalence, particularly in blue jeans. The abundance of blue cotton in society and its limited variations in features can diminish the probative value of its presence on items of evidence. While a pair of blue jeans may be constructed with a combination of natural and manufactured fibers, the most likely fiber type to be transferred between sources is cotton. In this study, a comprehensive analytical approach to blue jean fiber analysis was explored to determine if …

Cellular Autofluorescence Signatures For Determining Time Since Deposition Of Whole Blood, Hannah Lamer

Master of Science in Forensic Science Directed Research Projects

Knowledge of the relative window of time that evidentiary biological material was deposited at a crime scene, referred to as the time since deposition (TSD), would help investigators determine which evidentiary items are most probative and assist with scene reconstruction. One commonly encountered body fluid at a crime scene is blood. Various methods for estimating TSD of bloodstains have been developed, but none to date have been validated for use in the forensic laboratory. Recently, flow cytometry measurements of cellular autofluorescence and size/structure have been investigated as a signature for TSD of saliva and touch epidermal cells. This study assessed …

A Novel Dual Configuration Dart/Uhplc-Ms/Ms System For The Rapid Analysis Of Psilocybin-Containing Mushrooms And Other Seized-Drug Submissions, Aron R. Jaffe

Master of Science in Forensic Science Directed Research Projects

The use and availability of controlled substances is highly dynamic. When a classical or novel psychoactive substance becomes popular, an influx of seized-drug evidence submissions closely follows, contributing to an ever-growing backlog of exhibits awaiting identification. The need for inclusive, rapid, and robust analytical methods is apparent, as demonstrated by recent growth in hallucinogen use. Psilocybin and psilocin, among other entheogens, have become increasingly popular and an increase of psilocybin mushroom seizures by law enforcement has followed. The structural similarity and thermal lability of many entheogens preclude their identification using many conventional analysis techniques. A DART and UHPLC were interchangeably …
