Wildfire And Decomposition: A Taphonomic Analysis Of Thermal Alterations And Decomposition, Ashley Novak

Department of Anthropology: Theses and Student Research

Within the field of forensic anthropology, practitioners may be faced with remains that have been thermally altered by thermal alterations caused by wildfire. Within the field, very little research has been conducted examining how these thermal events impact rates of decomposition. While research has been conducted generally on the effects of thermal alteration on decomposition, these studies do not look through this lens and provide answers to the question of how do thermal alterations caused by wildfires affect rates of decomposition? This research examines the effects of thermal alteration caused by wildfire on the rate of decomposition. A decompositional study …

Umfc #132: A Comprehensive Forensic Case Report, Allison Paige Mitchell

Graduate Student Theses, Dissertations, & Professional Papers

This case report of an individual designated as University of Montana Forensic Case 132 (UMFC 132) serves to partially fulfill the requirements for the Master of Arts (MA) degree in Forensic and Biological Anthropology. UMFC 132 is a complete human skeleton, used as part of the teaching collection in the University of Montana Forensic Anthropology Laboratory. The minimum number of individuals (MNI) of UMFC 132 is 1. The analysis of UMFC 132 was conducted according to bioarchaeological and forensic anthropological standards of skeletal assessment. UMFC 132 was estimated to be a mid-adult, between the ages of [30-40 years] of age …

Peoples Of India: The Use Of Craniometric Data To Distinguish A Separate Ancestral Group, Stephanie A. Craig

Graduate Student Theses, Dissertations, & Professional Papers

The Peoples of India come from an area with a long history of migrations into and out of the area. This area is considered the second most diverse genetically outside of Africa. Many would group these people as Asian due to the country’s location. However, when studies are done on the skeletal remains from this area, the remains tend to give results of mixed or indeterminate ancestry unless the analyst is familiar with identifying Peoples of India. This study aims to determine the Peoples of India as a separate ancestral group separated from Asians, Europeans, and Africans. To do this, …

Utilization Of Gis In Tracking Disinterment And Movement Of Unknown Us Wwii War Dead: Foundations For A Geospatial Approach To Addressing Commingled Remains, Ella Axelrod

Department of Anthropology: Theses and Student Research

In the aftermath of World War II, the US was faced with the monumental task of finding and identifying over 405,000 service members who did not survive the conflict (McDermott, 2005, p. 1). Of these 405,000, 81,000 remain missing and 2,498 remain unidentified in cemeteries across Europe alone (American Battle Monuments Commission, 2022). Often, these individuals were interred and disinterred multiple times, crossing the continent in the journey from loss incident or battlefield to their final resting place. Commingling, the accidental mixing of remains, is an ever-present concern in the forensic identification of individuals from mass casualty incidents (Belcher et …

Dismantling Binary Assumptions In Sex Estimation: Uplifting Trans And Gender Diverse Identities In Forensic Anthropology, Audrey Holbeck

Honors Program: Senior Projects (Public)

Forensic anthropology is a study within the field of physical anthropology that seeks to apply osteological expertise to legal and criminal situations. One of a forensic anthropologists’ most important jobs is to build a biological profile, consisting of age, biological sex, stature, and ancestry, in correspondence to an unidentified decedent. As we enter the third decade of the 21st century, instances of violence against trans and gender non-conforming individuals are unfortunately prominent, however, there has also been more awareness shed on trans activism. Trans individuals are at a higher risk of being victims of violent crime, and thus, forensic anthropologists …

Preliminary Study In More Effective Utilization Of 87sr/86sr Analysis In The Field Of Forensic Anthropology, Samantha Powers

Graduate Student Theses, Dissertations, & Professional Papers

Isotopic analyses are gaining attention in the field of anthropology. The current utilization of strontium isotopes primarily focuses on residence and migration patterns of past populations extracting data from tooth enamel to indicate early-life residence This study aims to identify a skeletal feature to be set as a field standard in strontium analysis of modern remains when seeking end-of-life residence, the impact of diagenesis on modern remains, and to test the accuracy of the petrous as an alternative to tooth enamel.

The results of this research were unable to suggest such a standard but gathered helpful data to be used …

Assessing The Validity Of The Estimation Of Population Affinity From The Maxillary Hard Palate: An Empirical Approach Using A Modern Forensic Sample, Christopher M. Goden

LSU Master's Theses

In response to Beathard and DiGangi’s (2020) call to action for empirical assessment of population affinity estimation methodology, this study investigates the validity of maxillary palate shape as an indicator of ancestral population affinity for human skeletal remains through the use of Elliptical Fourier Analysis (EFA) and Linear Discriminant Function Analysis (DFA). Further, this study also places emphasis on the expressed variation of palate shape within and between population groups exemplified by Principal Component Analysis (PCA) of EFA data.

Computed tomography scans of 180 individuals of Black, White, and Hispanic population affinities were obtained from the New Mexico Decedent Imaging …

The Role Of Forensic Anthropological Techniques In Identifying America's War Dead From Past Conflicts, William Belcher, Calvin Y. Shiroma, Lesley A. Chesson, Gregory E. Berg, Miranda Jans

Department of Anthropology: Faculty Publications

The Scientific Analysis Directorate of the U.S. Department of Defense's (DoD) Defense POW/MIA Accounting Agency (DPAA) is a unique entity within the U.S. Government. This agency currently houses the world's largest, accredited skeletal identification laboratory in the world, in terms of the size of the scientific staff, global mission, and number of annual identifications. Traditional forensic anthropology is used for the formation of a biological profile (biological sex, stature, population affinity/ancestry, and age) as well as trauma and pathologies that may be compared with historical records and personnel files. Since World War II, various scientists associated with DoD have conducted …

Estimation Of Age From The Auricular Surface Of The Ilium Through The Utilization Of 3d Scanning And Gis, Krista Bennett

LSU Master's Theses

The ability to produce age estimations for adult skeletons has been a focus of forensic anthropologists for decades. Most age estimation methods for adult remains provide age ranges that are too narrow, too broad, or too vague. This project sought to combine 3D scans with GIS to produce morphological maps of the auricular surface of the os coxa in order to identify quantifiable characteristics for age assessment that could be used for generating narrower age range estimates for older adult remains.

A NextEngine ™ HD Desktop 3D scanner was used to scan the auricular surfaces of 384 os coxae from …

A Retrospective Analysis And Method Validation Of Postmortem Interval Estimation In Louisiana, Sophia Reck

LSU Master's Theses

Forensic anthropologists are often called upon to assess the postmortem interval (PMI; i.e. time since death) of remains in varying states of decomposition and skeletonization. These assessments rely on familiarity with general taphonomic sequences and processes, in addition to experience with how these processes present in local environments and conditions. Assessment using such qualitative methods is a subjective process. Therefore, some researchers have developed formulae whose purpose is to estimate PMI in an objective format. In these instances, the resultant PMI estimation formulae were developed using local data and therefore have the potential for local applicability. Additionally, for some regions, …
