Application And Implications Of Radiocarbon Dating In Forensic Case Work: When Medico-Legal Significance Meets Archaeological Relevance, Benoit Bertrand, Thibault Clauzel, Pascale Richardin, Anne Bécart, Philippe Morbidelli, Valery Hédouin, Carina Marques

Anthropology Faculty Publications

The estimation of the postmortem interval for skeletal remains is a crucial aspect of forensic anthropology. This paper illustrates the importance of radiocarbon analysis for establishing medico-legal significance and supporting forensic identification, through the analysis of three case studies for which the years of both birth and death were investigated. In Audresselles, Northern France, a partial skull was discovered with no contextual information or identity. Radiocarbon dating yielded an average calibrated calendar age of 4232 BCE (92.5% probability), indicating significant archaeological value but no forensic relevance. In the second case, skeletal remains were found in the flooded underground of a …

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 …

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 …
