Hair Root Staining – What Can Hematoxylin Do for Your Laboratory?
Hair evidence collected as part of a forensic investigation has the potential to provide valuable source information through DNA analysis of its root. This webinar discusses the process of utilizing Hematoxylin staining in forensic casework as an indicator of hair root DNA suitability. The presenters demonstrate the process of staining hair roots with Hematoxylin, as well as provide visual examples of stained hair roots.

Just Solving a Hit-and-Run in Sin City
In episode two of our Case Studies Part 1 mini season Just Science sat down with Stacey Chepren, member of a trial team for prosecuting federal criminal misconduct cases to discuss a fatal pedestrian hit and run involving trace and digital evidence. On a quiet morning in the city limits of Las Vegas, a pedestrian in a well-lit crosswalk was struck by an impaired driver who left the scene. There were no witnesses, but authorities quickly pieced together the case through a vehicle's aftermarket paint job and neighborhood video footage.
Interlaboratory Comparison of SpermX and Conventional Differential Extractions
Scientists from three participating laboratories - University of Central Florida (UCF), Center for Forensic Science Research and Education (CFSRE), and InnoGenomics (IGT) - presented results obtained from mock sexual assault samples using the SpermX method and their in-house differential extraction method. All three laboratories processed identical sets of female:male mixture swabs at various ratios in triplicate and presented their experiences and insights from this study.

Just a Curious Case of Print Persistence
In episode one of our Case Studies Part 1 mini season, Just Science sat down with Michael Fagert, a certified latent print examiner at the Kansas Bureau of Investigation, to discuss a latent print phenomenon that is not often seen in casework. There are very few instances of identifiable fingerprints on cartridge cases recovered from crime scenes, as the firing process introduces adverse physical and thermal stressors to fingerprint residues.

Just the Forensic Laboratory Workforce, Part 2
In part two of the final episode of our Strengthening the Forensic Workforce Season, Just Science continued the conversation with Dr. Peter Stout, Dr. Ray Wickenheiser and Matthew Gamette discussing the future of the forensic workforce. FEPAC accredited institutions provide high quality forensic science education for undergraduate and graduate students. However, coursework does not adequately emulate what working in a forensic laboratory and pursuing a career in forensic science will entail.
Using Risk Management to Optimize Forensic Laboratory Operations
The use of risk management has been historically absent from the management of forensic science laboratories. While ISO 31000 (Risk Management Principles and Guidelines) and ISO 9001 (Quality Management System) emphasized risk management, it was not until ISO/IEC 17025: 2017 highlighted its importance that forensic science managers began to take note. Even since its inclusion in ISO/IEC 17025, there remains a misunderstanding on what risk management is and how it can be used to improve laboratory operations.

Just the Forensic Laboratory Workforce, Part 1
In Episode eight of our Strengthening the Forensic Workforce Season, just sat down with Dr. Peter Stout, president of the Houston Forensic Science Center, Dr. Ray Wickenheiser, Director of the New York State Police Crime Laboratory System and Matthew Gamette, Director of the Idaho State Police Forensic Services Laboratory System, to discuss their perspectives on forensic science training and recommendations for students and faculty and FEPAC accredited programs. FEPAC accredited institutions are preparing students for future jobs in crime laboratories across the United States.
Tribal Crime, Justice, and Safety, Part 1
Research indicates that Native American persons experience crime victimization at higher rates than non-Native people. Furthermore, the unique position of American Indian and Alaska Native tribes as both sovereign nations and domestic dependents of the U.S. creates jurisdictional complexities in responding to crime, justice, and safety. Senior social and behavioral scientist Christine (Tina) Crossland discusses NIJ’s research on these topics, especially on the prevention of violence towards American Indians and Alaska Natives. Communications Assistant Stacy Lee Reynolds hosts.
Human Factors in Forensic Science Practice
The Forensic Technology Center of Excellence recently published a collection of five articles as a Special Issue in Forensic Science International (FSI): Synergy. These articles are known collectively as the Human Factors in Forensic Science Practice Sourcebook. The sourcebook is intended to educate forensic science practitioners and managers on the ways human factors can impact forensic science practice both positively and negatively and to expand the discussion beyond issues of bias.

Just Forensic Toxicology and Professional Partnerships
In Episode seven of our Strengthening the Forensic Workforce Season, Just Science sat down with Dr. Karen Scott, an Associate Professor at Arcadia University, and Dr. Jarrad Wagner, a Professor at Oklahoma State University, to discuss research collaborations, keeping on top of the dynamic drug landscape encountered in forensic toxicology case work. One of the requirements of FEPAC accreditation is that programs maintain partnerships with external collaborators such as forensic science laboratories and professional organizations.
Just Trace Evidence from Classroom to Courtroom
In Episode six of our Strengthening the Forensic Workforce Season, Just Science sat down with Dr. Brooke Kammrath, a Professor of Forensic Science at the University of New Haven, and Dr. Tatiana Trejos, an Assistant Professor in the Department of Forensic and Investigative Science at West Virginia University to discuss career paths for individuals trained in trace evidence analytical methods. Trace evidence analysts are tasked with extracting information from small quantity samples like glass, paint fibers and gunshot residue to shed light on what possibly occurred at a crime scene.
The Evidence We Leave Behind, Part 2
Just the Components of Forensic Biology and DNA
In Episode five of our Strengthening the Forensic Workforce Season, Just Science sat down with Dr. Robin Cotton, Director of the Master of Science Program and Biomedical Forensic Sciences at Boston University School of Medicine, and Dr. Daniele Podini, a professor in the Department of Forensic Sciences at the George Washington University to discuss forensic biology and DNA. Forensic biology can be described as the application of biochemistry and cellular biology to solve forensic problems.
Developing Critical Thinking Skills via Table Top Exercises
When faced with a situation that defies existing policy or past experiences, managers need to be ready to lead their teams and/or calmly advise and guide their own commanders. Table-top exercises are an efficient way to deliver this training and improve your teams' readiness for unexpected crises.
