Probabilistic genotyping is a tool that uses computing power to aid in the identification of possible genotype sets within DNA typing results and to calculate likelihood ratios to estimate evidentiary weight. In this installment of Probabilistic Genotyping of Evidentiary DNA Typing Results, we will detail the background and principles of biostatistical analysis, to include match probabilities, likelihood ratios and other specific topics aimed at furthering understanding of the statistical basis of probabilistic genotyping.

Based on the review of various forms of STR typing results and factors that impact the presence or condition of DNA on evidence, instructors in this installment of Probabilistic Genotyping of Evidentiary DNA Typing Results lay a foundation for the interpretation of forensic DNA typing results. The session will begin with background information on forensic DNA analysis, including terminology and mechanisms, to help all participants comprehend the material covered in this series.

In this webinar, the presenter will cover key components of successful onboarding in a crime lab, including setting employee expectations and making the employee feel like part of the team.  The presenter will go over an onboarding checklist so you can devise one that suits your agency’s needs.  Lastly, the presenter will discuss how successful onboarding can get the new employee “fired up” and increase employee engagement overall.   

This webinar will provide an overview of the validation, implementation of 3D  technology at the FBI Laboratory’s Firearms/Toolmarks Unit. This presentation will highlight the process, including Standard Operating Procedures, laboratory workflow, selection of casework, blind verification, reexamination of casework using light microscopy and Daubert preparation.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on June 2, 2021, as part of the 2021 ASCLD Train the Director Series.

This webinar will facilitate a discussion about bias in a crime laboratory including what is bias in forensics, how it can impact your operations, why it is important, and considerations when building this culture. The webinar will include important aspects of an unbiased culture, symptoms that your culture is biased, and examples from the Phoenix Police Department, the Virginia Department of Forensic Sciences, and ICITAP’s.
