Activity 6-6 Fingerprint Matching: Answer Key
(Note: A specific "Activity 6-6" was not provided. The following is a hypothetical example. Replace this with the actual activity and its corresponding answers.)
Let's assume Activity 6-6 involves comparing a latent fingerprint (found at a crime scene) with several known fingerprints from suspects. The answer key would detail the matching points between the latent print and the correct suspect's fingerprint. This would typically involve identifying minutiae points such as ridge endings, bifurcations, and dots. The answer key should clearly indicate:
The matching fingerprint: Clearly identify which known fingerprint (e.g., suspect #3) matches the latent print.
Matching minutiae points: Detail the specific locations of at least 12-15 corresponding minutiae points between the latent print and the matching known print. A diagram showing these points is crucial.
Reasoning: Provide a concise explanation justifying the match based on the identified minutiae points and their relative positions.
Best Practices for Fingerprint Matching
Proper Illumination: Ensure adequate and even lighting to avoid shadows that obscure ridge detail.
Magnification: Utilize appropriate magnification tools (microscopes, magnifying glasses) to examine fine details.
Systematic Approach: Follow a methodical approach, comparing specific areas and minutiae points systematically.
Documentation: Meticulously document all observations, including the number and location of matching minutiae points. Photography is essential.
Comparison Techniques: Utilize different comparison techniques such as side-by-side, overlay, and ACE-V (Analysis, Comparison, Evaluation, Verification) method.
Quality Control: Establish quality control measures to ensure accuracy and consistency.
Common Pitfalls to Avoid in Activity 6-6 Fingerprint Matching
Insufficient Minutiae: A match shouldn't be declared based on too few corresponding minutiae points.
Poor Quality Prints: Damaged, smudged, or incomplete prints can lead to inaccurate conclusions.
Subjectivity: Avoid subjective interpretations; rely on objective observations of minutiae.
Ignoring Dissimilarities: Any significant dissimilarities between the latent and known prints should be carefully considered.
Rushing the Process: Careful and thorough examination is paramount; rushing can lead to errors.
Lack of Proper Training: Inadequate training in fingerprint analysis techniques can result in mistakes.
Conclusion:
Accurate fingerprint matching is crucial in forensic investigations. Activity 6-6 provides valuable hands-on experience, but mastering this skill requires diligent practice and a thorough understanding of best practices and potential pitfalls. By following the guidance outlined in this comprehensive answer key and adhering to established procedures, you can enhance your accuracy and reliability in fingerprint analysis. Remember that this is a complex field demanding meticulous attention to detail and continuous professional development.

| activity 6 6 fingerprint matching answer key: Forensic Gait Analysis Ivan Birch, Michael Nirenberg, Wesley Vernon, Maria Birch, 2020-07-07 Gait analysis is the systematic study of human walking, using the eye and brain of experienced observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles. Since Aristotle’s work on gait analysis more than 2000 years ago, it has become an established clinical science used extensively in the healthcare and rehabilitation fields for diagnosis and treatment. Forensic Gait Analysis details the more recent, and rapidly developing, use of gait analysis in the forensic sciences. The book considers the use of observational gait analysis, based on video recordings, to assist in the process of identification or exclusion. With the increase in use of CCTV and surveillance systems over the last 20 to 30 years, there has been a steady and rapid increase in the use of gait as evidence. Currently, gait analysis is widely used in the UK in criminal investigations, with increasing awareness of its potential use in the US, Europe, and globally. The book details the history of the science, current practices, and of the emergent application to establish best-practice standards that conform to those of other forensic science disciplines. Engagement with the Forensic Science Regulator, and the Chartered Society of Forensic Sciences in the UK, and the International Association for Identification has helped to ensure and enhance the quality assurance of forensic gait analysis. However, there remains a fundamental lack of standardized training and methodology for use in evidentiary and investigative casework. This book fills that void, serving as one of the first to describe the current state of practice, capabilities and limitations, and to outline methods, standards of practice and expectations of the gait analyst as a forensic practitioner. Forensic Gait Analysis reflects current research and forensic practice and will serve as a state-of-the-art guide to the use of gait analysis in the forensic context—for both education and training purposes. It will be a welcome addition to the libraries of professionals in the areas of podiatry, gait analysis, forensic video analysis, law enforcement, and legal practice. |

Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book. |

| activity 6 6 fingerprint matching answer key: Inside the Cell Erin E Murphy, 2015-10-06 Josiah Sutton was convicted of rape. He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others -- arrest, swab, match, conviction. But there was just one problem -- Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of stop and spit. DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness. |

| activity 6 6 fingerprint matching answer key: Microbial Forensics Bruce Budowle, Steven E. Schutzer, Roger G. Breeze, Paul S. Keim, Stephen A. Morse, 2010-10-27 Microbial Forensics is a rapidly evolving scientific discipline. In the last decade, and particularly due to the anthrax letter attacks in the United States, microbial forensics has become more formalized and has played an increasingly greater role in crime investigations. This has brought renewed interest, development and application of new technologies, and new rules of forensic and policy engagement. It has many applications ranging from biodefense, criminal investigations, providing intelligence information, making society more secure, and helping protect precious resources, particularly human life. A combination of diverse areas is investigated, including the major disciplines of biology, microbiology, medicine, chemistry, physics, statistics, population genetics, and computer science. Microbial Forensics, Second Edition is fully revised and updated and serves as a complete reference of the discipline. It describes the advances, as well as the challenges and opportunities ahead, and will be integral in applying science to help solve future biocrimes. - A collection of microbiology, virology, toxicology and mycology as it relates to forensics, in one reference - New and expanded content to include statistical analysis of forensic data and legal admissibility and the standards of evidence, to name a few - Includes research information and application of that research to crime scene analysis, which will allow practitioners to understand and apply the knowledge to their practice with ease |

Participants reviewed the current status of selection and training of forensic scientists who specialize in pattern evidence and discussed how tools used in I-O psychology to understand elements of a task and measure aptitude and performance could address challenges in the pattern evidence domain of the forensic sciences. This publication summarizes the presentations and discussions from the workshop. |
| activity 6 6 fingerprint matching answer key: Criminal Investigation James W. Osterburg, Richard H. Ward, 2013-04-29 This text presents the fundamentals of criminal investigation and provides a sound method for reconstructing a past event (i.e., a crime), based on three major sources of information — people, records, and physical evidence. Its tried-and-true system for conducting an investigation is updated with the latest techniques available, teaching the reader new ways of obtaining information from people, including mining the social media outlets now used by a broad spectrum of the public; how to navigate the labyrinth of records and files currently available online; and fresh ways of gathering, identifying, and analyzing physical evidence. |
| activity 6 6 fingerprint matching answer key: Identifying the Culprit National Research Council, Division of Behavioral and Social Sciences and Education, Committee on Law and Justice, Policy and Global Affairs, Committee on Science, Technology, and Law, Committee on Scientific Approaches to Understanding and Maximizing the Validity and Reliability of Eyewitness Identification in Law Enforcement and the Courts, 2015-01-16 Identifying the Culprit: Assessing Eyewitness Identification makes the case that better data collection and research on eyewitness identification, new law enforcement training protocols, standardized procedures for administering line-ups, and improvements in the handling of eyewitness identification in court can increase the chances that accurate identifications are made. This report explains the science that has emerged during the past 30 years on eyewitness identifications and identifies best practices in eyewitness procedures for the law enforcement community and in the presentation of eyewitness evidence in the courtroom. In order to continue the advancement of eyewitness identification research, the report recommends a focused research agenda. |
| activity 6 6 fingerprint matching answer key: Biometric Recognition National Research Council, Division on Engineering and Physical Sciences, Computer Science and Telecommunications Board, Whither Biometrics Committee, 2010-12-12 Biometric recognition-the automated recognition of individuals based on their behavioral and biological characteristic-is promoted as a way to help identify terrorists, provide better control of access to physical facilities and financial accounts, and increase the efficiency of access to services and their utilization. Biometric recognition has been applied to identification of criminals, patient tracking in medical informatics, and the personalization of social services, among other things. In spite of substantial effort, however, there remain unresolved questions about the effectiveness and management of systems for biometric recognition, as well as the appropriateness and societal impact of their use. Moreover, the general public has been exposed to biometrics largely as high-technology gadgets in spy thrillers or as fear-instilling instruments of state or corporate surveillance in speculative fiction. Now, as biometric technologies appear poised for broader use, increased concerns about national security and the tracking of individuals as they cross borders have caused passports, visas, and border-crossing records to be linked to biometric data. A focus on fighting insurgencies and terrorism has led to the military deployment of biometric tools to enable recognition of individuals as friend or foe. Commercially, finger-imaging sensors, whose cost and physical size have been reduced, now appear on many laptop personal computers, handheld devices, mobile phones, and other consumer devices. Biometric Recognition: Challenges and Opportunities addresses the issues surrounding broader implementation of this technology, making two main points: first, biometric recognition systems are incredibly complex, and need to be addressed as such. Second, biometric recognition is an inherently probabilistic endeavor. Consequently, even when the technology and the system in which it is embedded are behaving as designed, there is inevitable uncertainty and risk of error. This book elaborates on these themes in detail to provide policy makers, developers, and researchers a comprehensive assessment of biometric recognition that examines current capabilities, future possibilities, and the role of government in technology and system development. |
