Game Over: The Prosecution of Mell Hall, Part 3

March 2017

Former Major League Baseball player Mel Hall is known for many things, but his athletic career is shadowed by a severe crime: preying on underage girls. In 2009, Hall was convicted of three counts of sexual assault of a child and two counts of indecency with a child. In this presentation, survivor Chaz discussed her personal story and the methods Hall used to manipulate her family into trusting him.

Emerging Forensic Research Series: Forensic Biology

April 2019

Forensic science research and development plays a key role in the advancement of the practice of forensic science, as noted by the 2009 National Academies of Science report “Strengthening Forensic Sciences in the United States: A Path Forward.”

This webinar was presented by the NIJ Forensic Technology Center of Excellence on April 9, 2019.

New Scientific Working Group on DNA Analysis Methods (SWGDAM) Recommendations on Communicating Likelihood Ratios

October 2018

SWGDAM recently issued recommendations on genotyping results reported as likelihood ratios, designed to promote consistency among laboratories. Members of the committee will discuss the recommendations and their foundations.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on October 18, 22018.

New Mexico Decedent Image Database: Taking 3D Measurements with Images

October 2020

This webinar will demonstrate the use of the open source 3D Slicer software platform (https://www.slicer.org/) for visualizing 3D medical imaging datasets and collecting quantitative data from those images, including linear/angular, landmark-based, and volumetric data.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on October 28, 2020.

New Mexico Decedent Image Database: Opening and Viewing Image Data

October 2020

In the third webinar, participants will learn about the image data included in the New Mexico Decedent Image Database, including how to open and view an image series, the different viewing functions, and how to access detailed information about the images.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on October 21, 2020. 
 

New Mexico Decedent Image Database: Accessing and Using Metadata

October 2020

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.

New Mexico Decedent Image Database: Overview of Accessing the Database and Searching

October 2020

This first webinar is an introduction to NMDID. Attendees will learn about the history of the database and the team that developed it. There will be a tour of the website, including data use agreement, “how to use” videos, descriptions of basic data types, and an introduction to the data dictionary.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on October 7, 2020. 

An Automated Single Cell Separation Technique to Improve Mixture Deconvolution

November 2020

This webinar will provide an evaluation of the DEPArray™, a system that enables the identification, separation, and recovery of single cells or groups of cells from heterogeneous mixtures. The workflow described in this webinar will highlight the impact this instrument, with standard forensic processes, will have on processing sexual assault evidence and improving the success of single cell analyses.

Effects of DNA Extraction Methods on Recovery, Degradation, and Loss

August 2020

Many working with genomic DNA can afford to lose large portions of it during its extraction without negatively impacting downstream analysis.  However, with work targeting highly degraded DNA sources, retention of every molecule can be key to successful analyses.   This webinar addressed the insufficient documentation of absolute efficiencies of extraction methods and the nature of DNA loss associated with the study of low copy number and degraded DNA samples.

Network Forensics: Challenges and Tools

August 2020

This webinar introduced the importance of network forensics, which included capturing network traffic and reconstructing digital artifacts. Presenters discussed big data challenges, open-source tools, and the new toolkit FileTSAR.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on August 12, 2020.

PACE™: Rapid and Automated Artifact Identification and Number of Contributor Prediction

July 2020

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.

Intact Low Explosives Analysis with an Emphasis on Microscopical Methods

July 2020

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.
