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 …

The assignment requires students to find the most prominent scholarly research in forensic sciences and discuss its efficacy. Further, the research leads students to discuss the potential limitations investigators must consider when examining forensic evidence. Lastly, students find at least six scholarly sources to provide an in-depth analysis of the research.

Sarah begins by discussing the history of forensic science and the ever-increasing technology used in …

The Contribution Of Forensic Science To Wrongful Convictions: An Analysis Of Forensic Expert Testimony, Parker Gunter

Honors Theses

The purpose of this study was to explore the progression and potential improvement of forensic science in court. Errors is forensic science have contributed to the problem of wrongful convictions, but research surrounding forensic expert testimony over the last decade is lacking. The way that an expert explains evidence in court is important to gain a broader understanding for how forensic science may fail. The testimonies of forensic experts were analyzed both quantitatively and qualitatively to further understand the shortcomings in the field at the end of its journey through the criminal justice system. The results showed that the testimonies …

Policing Pregnancy "Crimes", Valena Beety, Jennifer Oliva

Articles by Maurer Faculty

The Supreme Court’s decision in Dobbs v. Jackson Women’s Health Organization held that there is no right to abortion healthcare under the United States Constitution. This Essay details how states prosecuted pregnant people for pregnancy behaviors and speculative fetal harms prior to the Dobbs decision. In this connection, it also identifies two, related post-Dobbs concerns: (1) that states will ramp up their policing of pregnancy behaviors and (2) that prosecutors will attempt to substantiate these charges by relying on invalid scientific evidence. This Essay examines the faulty forensic science that states have used to support fetal harm allegations and reminds …

Evaluating A Test For Shedding Propensity Using Tape Lifts From Different Skin Locations, Xiao M. Chen

Student Theses

The shedding propensity of a person can assist data interpretation in casework when assessing the possibility of passive transfer for DNA analysis. Past studies on shedding propensity evaluated palmar skin (washed and unwashed) deposits. This study compared different skin locations with respect to shedding propensity, and explored the potential of tape-lifts as a skin surface collection method. Eight different skin types and samples were collected with adhesive tape disks from 28 participants over three non-consecutive days; the washed and unwashed fingers from both hands, toe, and arm, neck below ear, and nape. Samples were extracted, quantified, amplified, genotyped, and evaluated …

The Absence Or Misuse Of Statistics In Forensic Science As A Contributor To Wrongful Convictions: From Pattern Matching To Medical Opinions About Child Abuse, Keith A. Findley

Dickinson Law Review (2017-Present)

The new scrutiny that has been applied to the forensic sciences since the emergence of DNA profiling as the gold standard three decades ago has identified numerous concerns about the absence of a solid scientific footing for most disciplines. This article examines one of the lesser-considered problems that afflicts virtually all of the pattern-matching (or “individualization”) disciplines (largely apart from DNA), and even undermines the validity of other forensic disciplines like forensic pathology and medical determinations about child abuse, particularly Shaken Baby Syndrome/Abusive Head Trauma (SBS/AHT). That problem is the absence or misuse of statistics. This article begins by applying …

Arc Mapping Methodologies & The Pursuit Of Magical Globules, Notches, & Beads: A Bridge Too Far To Establish Fire Origin?, Tom R. May, David J Icove

Lincoln Memorial University Law Review Archive

Expert fire investigators know the limits of arc mapping as an indicator of fire origin. Concerns about arc mapping are on the rise. There are doubts associated with arc-related artifacts, distinguishing “cause” from “victim” beads, visual vs. microscopic examinations, and even practitioner qualifications. Specific noteworthy complaints include: (1) overpromises on the technique’s precision, (2) exaggerated inferences from the available data, (3) failure to adequately account for potential methodological flaws, (4) deficient scientific rigor in establishing evidentiary fire origin-related reliability, (5) errors due to deficient practitioner training and experience, and (6) indeterminate findings based upon subjective visual analysis. An emerging industry …

A Model For Confronting Fire Investigation Errors, John J. Lentini

Lincoln Memorial University Law Review Archive

When faced with the challenge of defending someone accused of arson, counsel has several options but unless there is overwhelming evidence to indicate that this was in fact an arson, the first thing counsel should do is retain an expert. Arson is one of the few crimes for which it is necessary to first prove that a crime was committed. Over this author’s 45-year career, many false accusations of arson have resulted in either civil or criminal litigation. As stated in the 2009 National Academy of Sciences (NAS) report:

The simple reality is that the interpretation of forensic evidence is …

Terms Of Service: The Use And Protection Of Genomic Information By Companies, Databases, And Law Enforcement, Sophia Kallas

Honors Theses

Private genomic companies have become a popular trend in the last two decades by providing customers with information regarding their ancestry and health risks. However, the profiles received from these companies can also be uploaded to public databases for various purposes, including locating other family members. Both testing companies and public databases have private interests, and both are at risk of law enforcement intervention for the purpose of forensic familial searching. There is little federal legislation protecting the privacy of an individual’s genetic profile. Consequently, it has been up to federal agencies, state laws, and judicial precedents to prevent the …

Escaping The Fingerprint Crisis: A Blueprint For Essential Research, Meghan J. Ryan

Faculty Journal Articles and Book Chapters

There is a fingerprint crisis in the courts. Judges and jurors regularly convict criminal defendants based on fingerprint evidence, but there are serious questions about the accuracy and reliability of this evidence. The few studies delving into the accuracy and reliability of fingerprint examiners’ work suggest a high error rate and demonstrate that, when faced with the same prints under different conditions, fingerprint examiners frequently reach different results than they previously reached. Further, there is no scientific basis for fingerprint matching. It is unknown whether and to what extent fingerprints are unique; the degree to which fingerprints change under various …

Evidence On Fire, Valena Beety, Jennifer Oliva

Articles by Maurer Faculty

Fire science, a field largely developed by lay “arson investigators,” police officers, or similar first responders untrained in chemistry and physics, has been historically dominated by unreliable methodology, demonstrably false conclusions, and concomitant miscarriages of justice. Fire investigators are neither subject to proficiency testing nor required to obtain more than a high school education. Perhaps surprisingly, courts have largely spared many of the now debunked tenets of fire investigation any serious scientific scrutiny in criminal arson cases. This Article contrasts the courts’ ongoing lax admissibility of unreliable fire-science evidence in criminal cases with their strict exclusion of the same flimsy …

Firearm-Mark Evidence: Looking Back And Looking Ahead, David H. Kaye

Journal Articles

This article, written as a contribution to a festschrift for Paul Giannelli, surveys the development of the law on one type of feature-matching evidence that repeatedly attracted Professor Giannelli’s attention — “firearm-mark evidence.” By inspecting toolmarks on bullets or spent cartridge cases, firearms examiners can supply valuable information on whether a particular gun fired the ammunition in question. But the limits on this information have not always been respected in court, and a growing number of opinions have tried to address this fact.

The article explains how the courts have moved from a position of skepticism of the ability of …

A Review And Conceptual Model Of Factors Correlated With Postmortem Root Band Formation, Joseph Donfack, Hilda S. Castillo

United States Department of Justice: Publications and Materials

It is generally accepted within the forensic trace evidence community that a postmortem root band (PMRB) can appear in the root of hairs attached to remains during decomposition. Presently, the specific sequences of events and/or exact molecular signals that lead to the formation of a PMRB are not well understood. The published literature addressing the abiotic and biotic factors that correlate with the formation of PMRBs is reviewed and a conceptual model for the formation of PMRBs is proposed.

Potential Effects Of Ionizing Radiation On The Evidentiary Value Of Dna, Latent Fingerprints, Hair, And Fibers: A Comprehensive Review And New Results, Keith L. Monson, Sherine Ali, Michael D. Brandhagen, Martine C. Duff, Constance L. Fisher, Karen K. Lowe, Carna E. Meyer, Maria A. Roberts, Kyle R. Tom, Aaron L. Washington Ii

United States Department of Justice: Publications and Materials

An extensive literature review and new post-irradiation experimental results are presented of genotyping blood stains and hair, and physical examinations of latent fingerprints, hairs, and fibers. Results indicate that successful development of nuclear short tandem repeat (STR) and mitochondrial DNA sequence profiles from human blood and hair evidence is possible—up to a point—following exposure to gamma, neutron, beta, and alpha radiation at several levels that would most likely be present at this type of crime scene (i.e., a “dirty bomb,” etc.). Commencing at gamma radiation levels between 90 and 900 kGy, DNA analysis using conventional DNA techniques was unsuccessful. In …

The Technologies Of Race: Big Data, Privacy And The New Racial Bioethics, Christian Sundquist

Articles

Advancements in genetic technology have resurrected long discarded conceptualizations of “race” as a biological reality. The rise of modern biological race thinking – as evidenced in health disparity research, personal genomics, DNA criminal forensics, and bio-databanking - not only is scientifically unsound but portends the future normalization of racial inequality. This Article articulates a constitutional theory of shared humanity, rooted in the substantive due process doctrine and Ninth Amendment, to counter the socio-legal acceptance of modern genetic racial differentiation. It argues that state actions that rely on biological racial distinctions undermine the essential personhood of individuals subjected to such taxonomies, …

Forensics’ Fight: A Need For Aggressive Strategies Against Confirmation Bias, Madison Mcgowan

Themis: Research Journal of Justice Studies and Forensic Science

In 2009, the National Academy of Sciences produced a lengthy report illuminating significant weaknesses present within the forensic community. One complex fault found in forensics was conformation bias. Since it is within human nature to make decisions based on contextual information, assumptions, and pre-held opinions, confirmation bias is an issue that will continue to persist. Therefore, stronger efforts must be made to recognize and abate the problem of bias within the field of forensics in order to preserve the notion that forensic science exists to serve principles of both truth and justice. Accordingly, this paper argues for the fight against …

Changing The Culture Of Disclosure And Forensics, Valena Beety

Washington and Lee Law Review Online

This Essay responds to Professor Brandon Garrett’s Constitutional Regulation of Forensic Evidence, and, in particular, his identification of the dire need to change the culture of disclosing forensic evidence. My work on forensics is—similarly to Garrett’s—rooted in both scholarship and litigation of wrongful convictions. From this perspective, I question whether prosecutors fully disclose forensics findings and whether defense attorneys understand these findings and their impact on a client’s case. To clarify forensic findings for the entire courtroom, this Essay suggests increased pre-trial discovery and disclosure of forensic evidence and forensic experts. Forensic analysts largely work in police-governed labs; therefore, …

Hypothesis Testing In Law And Forensic Science: A Memorandum, David H. Kaye

Journal Articles

The Organization of Scientific Area Committees for Forensic Science (OSAC), was established to promote and develop forensic-science standards based on sound scientific principles. One of the first standards to be approved deals with declaring fragments of glass to be either distinguishable or indistinguishable in their chemical composition. This determination is important when it is suspected that small fragments associated with a defendant came from the scene of a crime involving broken glass. Because of instrumental measurement error, even fragments with identical elemental concentrations will display some differences. To account for measurement error, the standard uses statistical hypothesis tests that presume …

Discovering Forensic Fraud, Jennifer Oliva, Valena Beety

Articles by Maurer Faculty

This Essay posits that certain structural dynamics, which dominate criminal proceedings, significantly contribute to the admissibility of faulty forensic science in criminal trials. The authors believe that these dynamics are more insidious than questionable individual prosecutorial or judicial behavior in this context. Not only are judges likely to be former prosecutors, prosecutors are “repeat players” in criminal litigation and, as such, routinely support reduced pretrial protections for defendants. Therefore, we argue that the significant discrepancies between the civil and criminal pretrial discovery and disclosure rules warrant additional scrutiny.

In the criminal system, the near absence of any pretrial discovery means …

Probability, Individualization, And Uniqueness In Forensic Science Evidence: Listening To The Academies, David H. Kaye

David Kaye

Day in and day out, criminalists testify to positive, uniquely specific identifications of fingerprints, bullets, handwriting, and other trace evidence. A committee of the National Academy of Sciences, building on the writing of academic commentators, has called for sweeping changes in the presentation and production of evidence of identification. These include some form of circumscribed and standardized testimony. But the Academy report is short on the specifics of the testimony that would be legally and professionally allowable. This essay outlines possible types of testimony that might harmonize the testimony of criminalists with the actual state of forensic science. It does …

Ultracrepidarianism In Forensic Science: The Hair Evidence Debacle, David H. Kaye

David Kaye

For over 130 years, scientific sleuths have been inspecting hairs under microscopes. Late in 2012, the FBI, the Innocence Project, and the National Association of Criminal Defense Lawyers joined forces to review thousands of microscopic hair comparisons performed by FBI examiners over several of those decades. The results have been astounding. Based on the first few hundred cases in which hairs were said to match, it appears that examiners “exceeded the limits of science” in over 90% of their reports or testimony. The disclosure of this statistic has led to charges that the FBI “faked an entire field of forensic …

An Empirical Research Agenda For The Forensic Sciences, Jonathan J. Koehler, John B. Meixner Jr.

Scholarly Works

After the National Academy of Sciences issued a stunning report in 2009 on the unscientific state of many forensic science subfields, forensic science has undergone internal and external scrutiny that it had managed to avoid for decades. Although some reform efforts are underway, forensic science writ large has yet to embrace and settle upon an empirical research agenda that addresses knowledge gaps pertaining to the reliability of its methods. Our paper addresses this problem by proposing a preliminary set of fourteen empirical studies for the forensic sciences. Following a brief discussion of the courtroom treatment of forensic science evidence, we …
