No One Is Above The Law: Public Perception Of Prosecutorial Misconduct's Influence On Wrongful Convictions, Amanda N. Pappas

Honors Theses

Wrongful convictions pose a large threat to the integrity of the United States criminal justice system. While there are many known causes of wrongful convictions, such as eyewitness misidentification, ineffective counsel, and false confessions, the most egregious cause is prosecutorial misconduct. According to the National Registry of Exonerations, prosecutorial misconduct has been found in roughly half of the exonerations listed in the registry. Prosecutors have a tremendous amount of power in the criminal justice system through determining plea deals, obtainment of evidence, disclosure of evidence to the defense, and many more. Studies have been conducted that reveal the occurrence of …

Amino Acid Composition Analysis As A Means To Differentiate Hair Samples From Individuals Of Similar Demographics And The Effect Of Hair Treatments, Trisha Brady

Honors Theses

Hair is a forensically-relevant exhibit due to its ability to be shed, torn, or transferred during a crime. Current forensic hair analysis includes microscopic hair comparison and mitochondrial or nuclear DNA analyses, each with limitations. Novel methods, such as those evaluated herein, have potential to complement conventional techniques. These include evaluating functional groups with infrared (IR) spectroscopy, elements with laser induced breakdown spectroscopy (LIBS), and amino acid ratios with gas chromatography- mass spectrometry (GC-MS). Hair from two demographically similar individuals was divided into three sample groups per individual: untreated, bleached, and dyed. Spectral differences between individuals and treatments were evaluated …

Evaluation Of The Effect Of The Humic Acid Inhibitor On Forensic Genetic Investigations Of Human Skeletal Remains, Madeline King

Honors Theses

Postmortem survival of DNA in human skeletal remains occurs due to the compact microstructure of the skeleton and its ability to provide a strong, protective physical barrier to environmental insults. On a molecular level, DNA preservation in bones/teeth involves electrostatic interactions between the negatively-charged DNA backbone and positively charged calcium residues in hydroxyapatite, the latter of which is one of the main components of bone microstructure. Despite these protections, over time endogenous DNA becomes damaged, limiting our ability to detect it and affecting its utility in making a positive identification. Hence, forensic genetic investigations of unidentified human remains (UHRs) are …

Race And Social Class As Factors Associated With Sentence Disparities: A Survey Of Potential Jurors, Amanda Rickett

Honors Theses

Prior research has found that bias, along with other extralegal factors, leads to the sentencing disparities in the criminal justice system throughout the United States. The criminal justice system has implemented reforms to address these disparities. Furthering research on this issue, I analyze previous studies that tried to determine the effects of bias on the decisions made by judges and juries. Most importantly, the present study aimed to determine the effects of race and socioeconomic class of the defendant on the decisions on potential jurors using a vignette based survey with randomized assignment. The results suggest that the potential jurors’ …

Extraction Of Human Dna From Soil In A Simulated Clandestine Grave, Arely Joaly Parra Lopez

Honors Theses

Locard’s Exchange Principle states that “every contact leaves a trace.” The same principle applies when a perpetrator of a homicide decides to bury a victim in a clandestine grave. If a perpetrator originally buried a murder victim in haste to prevent discovery and then decided to later move the victim’s body to a remote location for disposal, decomposition fluids from the victim’s body (which contain cellular material and therefore DNA) would remain in the surrounding grave soil at the original burial site. It is possible that investigators could: 1) prove that a human body had once laid in that location …

Investigating The Use Of Saligae® To Identify Expirated Blood On Various Material, Maria Bigos

Honors Theses

Expirated bloodstains and impact bloodstains have very similar physical characteristics. The main way Blood Pattern Analysts identify bloodstains in based on their physical characteristics. This can lead to difficulty distinguishing between expirated blood and impact spatter. Expirated blood can be identified through the presence of air bubbles, however these are often only present on non-porous surfaces. However, if expirated bloodstains can be identified through the presence of saliva, this can provide an alternative way to identify expirated bloodstains. This study examined if SALIgAE can be accurately used to identify the presence of saliva in blood and thus, be a way …

Mental Health And Its Impact On The School-To-Prison Pipeline: A Look At Tennessee Schools, Briana Brady

The study is both quantitative and qualitative; it researched existing literature and theories on the subject matter and also sourced over 750 data points published by varying organizations and agencies. By using proxy data including school guidance counselor-to-student ratios, out of school suspension rates, and juvenile court referrals, this research tested whether or not a direct relationship existed between the number of school counselors and both out of school suspensions as well as juvenile court referrals. The findings …

Race, Sex, Exoneration, & Compensation: How Do They Relate? What Is Done? And What Needs To Be Done?, Sarah Emily Still

Honors Theses

Previous literature has noted multiple causes of wrongful conviction including mistaken eyewitness identification, false confessions, ineffective assistance of counsel, crime lab error, and prosecutorial misconduct. Over time, more wrongful convictions caused by these factors are overturned through the help of organizations such as the Innocence Project. With these increasing exonerations comes the increased needs of exonerated people. The previous literature has exemplified that exonerees have unique needs (Simms, 2016), but these needs are often not met by the compensation that is available (Chunias & Aufgang, 2008; Mandery et. al, 2013). This occurrence is problematic given that exonerees had to lose …

Unraveling The Mummy: The Effects Of Natural Mummification On The Recovery And Degradation Of Dna, Marissa Gandolfo-Muller

Honors Theses

As demonstrated through casework and research studies (Hawass et al., 2010; Gielda & Rigg, 2017), anthropogenic mummification and modern-day embalming can expedite degradation of DNA. Current research in the field of forensic mummification is sparse and little research has been done on quantifying naturally mummified DNA (Leccia et al., 2018; Shved et al., 2014). This research focuses on observing and quantifying the differences in the recovery and degradation of DNA from specimens that have been naturally mummified. This research on natural, forensic mummies is a blend of experimental archeology and postmortem DNA analysis.

In this study, two control specimens and …

Investigation Of Palatal Rugoscopy For Forensic Human Identification, Cameron Filipe

Honors Theses

Human identification is critical to the field of forensic science as well as in many sub-disciplines, including forensic pathology, forensic anthropology, and forensic odontology. While few widely-accepted methods of identification dominate the discipline (primarily fingerprint and dental record analysis), the study of palatal rugae patterns (rugoscopy) is an emerging tool in human identification. Some studies suggest that patterns of the palatal rugae are an individualizing characteristic among humans. While the use of rugoscopy for identification has been explored as an identifying marker in the dental and orthodontic communities, its use for forensic applications is not widely recognized. Also, while some …

The Opportunities And Challenges Of Internet Of Things Evidence In Regard To Criminal Investigations, Nathan Mcclaran

Honors Theses

As internet-connected devices become more prevalent, the need for police and law enforcement to be able to utilize these devices when solving crimes steadily increases. Law enforcement agencies are already aware of the opportunities and challenges when interacting with computers and mobile cellular devices, but many agencies are unable to utilize these avenues of evidence because of limited access to resources able to forensically examine computing devices. In addition, the introduction of internet of things devices, such as Amazon Alexa and other microphone or camera connected devices, allows new opportunities for law enforcement agencies to gather digital forensic evidence either …

Cultivation Effects From Television Crime Dramas To Forensic Practices, Stephanie P. Mobley

Honors Theses

Television and its effects have been frequently studied due to the prevalence of television in today’s society. Cultivation theory examines these effects by claiming that people’s perceptions of the real world are shaped by the social reality portrayed on television. This paper used this theory to examine a link between college student’s viewership of television crime dramas and their opinions about forensic practices. It used quantitative survey questions and previous research to come to conclusions for the research questions. The three research questions asked whether frequent viewing of crime dramas cultivated false beliefs about three forensic practices, (fingerprint analysis, polygraph …

Self-Determination In American Discourse: The Supreme Court’S Historical Indoctrination Of Free Speech And Expression, Jarred Williams

Honors Theses

Within the American criminal legal system, it is a well-established practice to presume the innocence of those charged with criminal offenses unless proven guilty beyond a reasonable doubt. Such a judicial framework-like approach, called a legal maxim, is utilized in order to ensure that the law is applied and interpreted in ways that legislative bodies originally intended.

The central aim of this piece in relation to the First Amendment of the United States Constitution is to investigate whether the Supreme Court of the United States has utilized a specific legal maxim within cases that dispute government speech or expression regulation. …

Rights For The “Non-Conforming” Woman: The Intersectionality Of The Fight For Women’S Rights And Lgbtq+ Rights In Argentina, Talia C. Housman

Honors Theses

Argentina has faced many challenges throughout its history of activism as the people have pushed for an equal society. Different movements have sprung up over the years, but they have begun to twist together in recent times due to the need for support during repressive regimes. This brings into question the concept of intersectionality, which spans feminist, queer, and legal theory in its attempt to explain the need for overlap, modeling the natural development of personal identities and groups like family. The feminist movement and the LGBTQ+ movements have woven together in many rallies, especially during El Encuentro Nacional de …
