This webinar focused on the use of PACE™, a method developed by Syracuse University, to perform artifact management and probabilistically predict the number of contributors (NOC) in forensic DNA samples. This is performed using a combination of biological modeling and machine learning, permitting high accuracy NOC calls (greater than 90%) of complex mixtures. It does so rapidly (seconds to minutes) without the need for high performance computing resources.

This webinar discussed intact low explosives analysis with a focus on microscopical methods. It covered terminology for explosives, the rationale of low explosives analysis for most crime laboratories, six categories of low explosives, and examples of three analyses using microscopical methods.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on July 16, 2020.

This webinar highlighted the results of a full developmental validation of a method that estimates the A Posteriori Probability (APP) of the number of contributors in a DNA sample(NOC), and demonstrated that estimating the APP based on peak heights outperforms methods that rely on binary determinations alone. This presentation focused on including the true NOC in Likelihood Ratio interpretations and on repeatability.

Highly toxic, synthetic drugs introduce significant health hazards to the forensic laboratory.  Understanding current knowledge and best practices will help laboratories manage their liability. This presenter covered topics such as known risks of handling hazardous drugs, creating a practical framework for the assessment, development, and improvement of safety systems, and additional research needed regarding exposure risks.

How prepared are schools for emergencies? Dr. Silva discusses her NIJ-funded research that looked at whether or not federal guidelines were reaching schools; the levels of emergency preparedness at the state, district, and school level; what we can learn from well-prepared schools, both best practices and challenges.

Dr. Scalora discusses his NIJ-funded research that looks at how police engagement and collaboration with rural school districts impact emergency operation planning and other aspects of school violence prevention.

This presentation provided an overview of the activities and programs the Phoenix Police Department’s Crime Lab has implemented and the corresponding impact to the organizational culture and employee morale.

This webinar presented the findings of the ASCLD/NIJ collaborative Gap Assessment of Stress, Vicarious Trauma and Resiliency for Forensic Science Professionals. The assessment gathered survey responses from forensic and medical examiner laboratories to evaluate vicarious trauma, burnout, job satisfaction, and participants perceptions of their organization’s resiliency efforts.  Our findings inform future directions in research, policy, and practice to better manage stress and increase resiliency among forensic professionals.

Residential structure fires are predominantly fueled by synthetic contents and commonly become ventilation-limited.  Therefore accounting for the impact of ventilation on fire is important. Examining flow paths within the structure can aide in fire pattern analysis.

Dr. Hamilton discusses his research on risk assessment, needs assessment, and responsivity, examining how the interaction between adults' and juveniles' predictors impact their likelihood of recidivism — and the programming and services that are provided for each.

Dr. Sullivan discusses his research to understand implementation procedures and practice in the juvenile justice system that facilitate adoption of these tools and their appropriate use.

Dr. Vincent discusses her research on how risk assessment and risk need responsivity affect change in how we handle individuals in the justice system.

NIJ’s American Indian and Alaska Native Travel Scholarship Program Scholars discuss:

• Why they applied to the program.
• Which conference they chose to attend and why.
• Why representation of American Indian and Alaska Native is important in the field of criminal justice.
• What conference sessions they chose to attend and which they found most interesting.
• How they want to contribute to the fields of tribal and criminal justice.

Using a typical OEM paint system, the PDQ Maintenance Team will walk through the best practices to efficiently use the database and spectral libraries to identify the most likely source of an unknown paint system. Details gathered from this process include manufacturing plant, year range, and models.

Sergeant Jason Moran of the Cook County (IL) Sheriff’s Office discusses the current situation of cold cases in the United States, why it’s important to establish cold case units, how current tools and technology can help solve cold cases, and what National Institute of Justice resources are available to assist in solving cold cases.

Sergeant Moran was a participant on an NIJ Saturday Session panel at IACP 2019.

Cory Haberman, Assistant Professor, University of Cincinnati, discusses his work as an NIJ LEADS Academic and the value of having training researchers working directly with law enforcement agencies. 

Captain Ivonne Roman, Newark (NJ) Police Department, describes how her participation in NIJ’s LEADS Program has helped her research on women in policing, some of her findings, and describes how LEADS has benefited her career growth.

Lieutenant Piotrowski, New Jersey State Police, discusses drug monitoring programs. With this program, his agency collects multiple drug-related data sets to ultimately have an impact on mitigating the impact of drugs in his community. Topics include the benefits of implementing a drug monitoring program, some of the outcomes of the program, and how federal funding can help an agency start such a program.

Lieutenant Piotrowski participated in an NIJ Day panel at the 2019 International Association of Chiefs of Police Conference and Expo.

Antoinette Tull, Human Resources Division Chief, Richmond (VA) PD, discusses how law enforcement recruitment and retention strategies have changed in recent years, new retention strategies to attract millennial recruits, what retention strategies budget restricted agencies can consider implementing, and how NIJ can play a role in researching or evaluating strategies for recruitment and retention.

Antoinette Tull was a participant on an NIJ Saturday Session panel at IACP 2019.

Captain Baughman of the Kansas City (MO) Police Department answers the question “What is risk terrain modeling?” and explains how it differs from crime mapping, what resources his agency deploys at high risk areas, and the results he has seen form using risk terrain models.

Sergeant Jeffery Egge of the Minneapolis Police Department, and NIJ LEADS Scholar alum, discusses his experience with leads including how the program benefited his agency and his use of date to address gun violence and the opioid epidemic and the city's sentinel events review of overdose fatalities. Sergeant Egge also discusses his current work looking at investigative closures.
