Forensic and Investigative Sciences

Description

Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.  

NIJ’s forensic science research and development program focuses on basic and applied scientific research with the intent to:

  • Direct the findings of basic scientific research in broader scientific fields applicable to forensic science.
  • Apply forensic science research to the development of highly discriminating, accurate, reliable, cost-effective, rapid methods for the identification, analysis and interpretation of physical evidence.
  • Expand the scientific basis of forensic methods.
  • Produce useful materials, devices, systems or methods that have the potential for forensic application.
  • Increase the body of knowledge to guide and inform forensic science policy and practice.

Just Identifying Individuals with Forensic Genetic Genealogy

September 2022

In episode one of our Applications of Forensic Science for Human Identification season, Just Science sat down with Dr. Heather McKiernan, a Research Forensic Scientist at RTI International, and Ashley Rodriguez, a Research Public Health Analyst at RTI International, to discuss the use of forensic genetic genealogy in identifying human remains. Oftentimes unknown human remains are recovered fully or partially skeletonized, with no close biological relatives in CODIS to facilitate identification.

Just Solving Cold Cases with Forensic Genetic Genealogy

August 2022

In episode four of our Case Studies: Part 1 mini season, Just Science sat down with Leighton D'Antoni, the Assistant District Attorney in Dallas County, Texas, to discuss how forensic genetic genealogy was used as an investigative tool to help solve a series of violent cold cases. In the 1980s, several violent sexual assaults occurred in Dallas County, Texas and Shreveport, Louisiana. These cases were all linked by a foreign DNA profile; however, no suspect was found and the cases went cold.

Just Forensic Archaeology and Body Dump Sites

August 2022

In episode three of our Case Studies Part one mini season, Just Science sat down with Dr. Sharon Moses, an Associate Professor of Anthropology at Northern Arizona University, to discuss forensic archeology and locating victims of no-body homicides. Forensic archeologists can play a critical role in body recovery and search strategies for locating human remains because homicide offender’s choices and body disposal sites are influenced by various social and environmental factors.

Hair Root Staining – What Can Hematoxylin Do for Your Laboratory?

August 2022

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

August 2022

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

August 2022

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

August 2022

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.

What Keeps You Awake at Night: Risk, Leading Change, and Challenging Decisions

July 2022

Crime laboratories are exposed to risks each and every day, and it is the job of organizational leaders to balance the severity of a consequence versus the frequency of occurrence, know the laboratory's risk exposure, and proactively mitigate that risk. This webinar will discuss accessing risk exposure, strategic planning, and managing change. Additionally, how to address the stress and anxiety associated with change will be discussed.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on July 26, 2022. 

Just the Forensic Laboratory Workforce, Part 2

July 2022

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

June 2022

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.
