This session provides an overview of the fundamental principles of statistics as encountered and applied in forensic toxicology. Various elements of statistics are often utilized or relied upon by scientists to describe produced results and to demonstrate if forensic instruments or processes are “working” or “in-control”. Here we establish the basic terminology for the principles of statistical analysis. Participants will begin to be better equipped to interpret and analyze forensic toxicology data accurately and effectively. 

George Mason University and the National Association of Attorneys General presents the National Center on Forensics Continued Training Plan to provide additional training sessions for more advanced information on the topics covered in the conference. In this training session, Dr. Mark Wilson will discuss how DNA is used to generate data for use in FGG.

This event was hosted by the National Center on Forensics under an award from the National Institute of Justice.
 

Well-trained forensics specialists are integral to ensuring justice across the United States. However, in the country's rural states and locations, this training can be hard to come by. 

The National Center on Forensics (NCF) is a partnership between George Mason University, the National Association of Attorneys General, the American Society for Clinical Pathology, and the Montana Forensic Science Division funded by the National Institute of Justice. This grant program aims to bring forensics training to the nation's underserved rural areas. 

It is well-known that bloodstain pattern analysis (BPA) on textiles is difficult and subject to many errors or misinterpretations. In this webinar, we probe the reason for this and suggest useful information that a bloodstain pattern analyst may be able to extract from the observed bloodstains. The data set demonstrates the roles of drop volume and impact speed in bloodstain formation on textiles.

While forensic DNA analysis can identify an individual(s) at a crime scene, it cannot identify the biological source from which that DNA was obtained – e.g. blood, saliva, or semen. Identification of the biological source of DNA can provide important contextual information for forensic investigations as well as evidence in court. Nearly all current methods used for body fluid identification are presumptive. Here we present a new proteomic mass spectrometry method for the confirmatory identification of blood, saliva, and semen.

Part I: GeoFOR is a free web-based collaborative forensic taphonomic application and database that utilizes geospatial technology and machine learning to deliver data-driven postmortem interval estimations to better facilitate identification and reconstruct events around the time of death. This presentation describes the geoFOR application and its potential for advancing the field of forensic science.  

Forensic anthropologists face the challenge of sorting remains from commingled assemblages. This webinar examines how chemical signatures of bone can complement physical reassociation strategies. Laser-induced breakdown spectroscopy (LIBS) offers rapid, visually non-destructive analysis that acquires chemical information from bone. Statistical evaluation of chemical profiles taken across 1284 bones from 45 individuals reveals that physicochemical variation exists between individuals and, consequently, can be used to classify the bones.

A world in crisis and a 24/7 media cycle demands consistent, clear, and effective communication from organizations tasked with death investigation and related responsibilities. Two seasoned professionals share their experiences reaching diverse stakeholders and engaging the public in the vital work of the largest medical examiner’s office in the country.

A roadmap to successfully utilizing contract forensic pathologists, also known as locum tenens, was presented by a Chief Medical Examiner and a Coroner with extensive experience in employing these useful contractors to perform forensic autopsies and other professional tasks in today’s environment of increasing caseloads. Topics include the forensic pathologist workforce shortage, scheduling, budgeting, fee structures, and different business models for the use of locum tenens forensic pathologists in busy Medical Examiner and Coroner offices. \

In the first installment of the 20230R&D Webinar Series, Dr. Sarah Seashols Williams from Virginia Commonwealth University, demonstrates the ability to classify body fluids using miRNA expression from DNA extracts with 92% accuracy, eliminating the need for RNA extraction, greatly reducing evidentiary sample consumption and processing time in forensic laboratories.

This recorded webinar, originally held September 28, 2023, provides information on NIJ’s Research Assistantship Program, which offers highly qualified doctoral students the opportunity to bring their expertise to NIJ to work across offices and program areas to obtain a practical and applied research experience. The program is a research focused professional development opportunity for doctoral students from all academic disciplines. NIJ provides funds to participating universities to pay salaries and other costs associated with research assistants who work on NIJ research activities.
