Just Managing Mass Fatality Incidents

February 2023

In episode four of our Unidentified Human Remains mini season Just Science sat down with Katharine Pope, a Research Public Health Analyst at RTI International, and Elissia Conlon, a Special Advisor to the New York City Office of Chief Medical Examiner, to discuss mass fatality incident management and disaster victim identification. A mass fatality incident includes any incident where there are enough fatalities to require the involvement of a special operation or organization such as a natural disaster, large transportation accident, or terrorist attacks.

Just Teeth and Technology

January 2023

In episode one of our Unidentified Human Remains mini season, Just Science sat down with Dr. Kenneth Aschheim, Assistant Chief Forensic Ontologist for the New York City Office of Chief Medical Examiner, to discuss how dental evidence can be used to help identify human remains. Due to their strength, heat resistance, and lack of decomposition over time, teeth are one of the most resilient substances found in the human body. As a result, forensic odontologists can use the teeth of decedents to match the antemortem dental records in order to help identify unknown human remains. Listen as Dr.

JustScience Podcast Season Overview: Applications of Forensic Science for Human Identification

Identifying unknown human remains requires the strategic use of investigative techniques and scientific methods. This includes utilizing various forensic methods to gather the decedent’s biometrics, collecting familial reference samples for comparison, and inputting available information into comprehensive databases to facilitate connections to cases nationwide and internationally. These efforts can help bring closure to families, identify victims of mass disasters, and find missing persons. Listen along...

National Missing and Unidentified Persons System

Overview

What is NamUs?

Resolving missing and unidentified persons cases is especially complex. Information-sharing across agencies and jurisdictions can be fragmented, paired with limited investigative resources and a high volume of cases. In many instances, significant time has passed since the person went missing. Still, we have a societal responsibility to ensure dignified and lawful outcomes. Each resolution can also uncover links to multiple crimes—and...

Overview of Forensic Anthropology

Forensic anthropologists examine skeletal human remains to assess age at death, sex, stature, and ancestry; identify injuries; and estimate the time since death to provide investigators with information that can assist in identifying a decedent.

Forensic odontologists examine the development, anatomy, and any restorative dental corrections of the teeth, such as fillings or extractions, to make a comparative identification of a person.

Bones and teeth are...
