MDI Myth: Nobody Cares About or Uses MDI Data

November 2024

Misconceptions abound regarding the role of medicolegal death investigation (MDI) professionals, particularly the pervasive belief that they solely work with and for the deceased. This perception often leads to a public reluctance in engaging with medical examiner and coroner (MEC) systems, especially from stakeholders who hold the proverbial purse strings. The reality is, MDI data impacts the living, from assisting grieving families to influencing public health at regional and even national levels.

MDI Myth: Rapid Toxicology Screening Tools Can Replace Traditional

October 2024

This session busts the myth that new toxicology screening tools can fully replace traditional toxicology testing. The session discusses the appropriate integration of current rapid toxicology screening tools into MEC offices as a method of triaging cases, rather than a determination of toxicology related causes of deaths.

Advances in Chemical Sorting of Commingled Remains Compressed

November 2023

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.

Transient Workforce in Forensic Pathology: Challenges, Rewards Compressed

November 2023

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. \

Modern Death Investigation: Hub and Spoke Models for Adequate Workforce

November 2023

This webinar describes the history, structure, and operations of the Virginia Office of the Chief Medical Examiner. The system includes four regional offices staffed by forensic pathologists supervising over 100 appointed Local Medical Examiners. Decedents requiring autopsy are transported to a regional office, while most external examinations are performed in the community by appointed Local Medical Examiners.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on November 7, 2023.
