Unidentified human remains

Just DNA Results in Rapid Time

February 2023

In episode two of our Unidentified Human Remains season, Just Science sat down with Neal Parsons, a Research Forensic Scientist at RTI International, to discuss how rapid DNA analysis has become an important method for identifying unknown human remains, especially in cases of mass fatality. Rapid DNA analysis is a fully automated process of developing DNA profiles without the need for a DNA laboratory or human interpretation.

Just Using Forensic Art and Anthropology for Identification

September 2022

In episode four of our Applications of Forensic Science for Human Identification Season, Just Science sat down with Katharine Pope, a Research Public Health Analyst at RTI International, Dr. Bruce Anderson, a forensic anthropologist with the Pima County Office of the Medical Examiner, and Joe Mullins, an instructor at the New York Academy of Art, to discuss human identification using forensic anthropology and facial approximations.

Just a Curious Case of Print Persistence

September 2022

In episode two of our Applications of Forensic Science for Human Identification Season, Just Science sat down with Bryan Johnson, the Major Incident Program Manager in the Federal Bureau of Investigation's Latent Print Unit, to discuss how postmortem prints can be used to help identify unknown decedents. One of the cheapest, easiest and fastest methods of identifying individuals is through friction ridge prints. However, challenges can arise in cases where trauma or decomposition affect quality of a decedent's hands.

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...

Just Identifying Individuals with Forensic Genetic Genealogy

September 2022

In episode one of our Applications of Forensic Science for Human Identification season, Just Science sat down with Dr. Heather McKiernan, a Research Forensic Scientist at RTI International, and Ashley Rodriguez, a Research Public Health Analyst at RTI International, to discuss the use of forensic genetic genealogy in identifying human remains. Oftentimes unknown human remains are recovered fully or partially skeletonized, with no close biological relatives in CODIS to facilitate identification.

Just Leveraging Databases for Human Identification

September 2022

In episode three of our Applications of Forensic Science for Human Identification season, Just Science sat down with Lori Bruski and Amy Jenkinson, two research public health analysts at RTI International to discuss inter-agency efforts to compile crime, missing persons and decedent information and comprehensive databases. In the digital age, criminal justice information can be uploaded into databases and organized in a searchable, centralized location, making it more accessible than ever.

Just Identifying Lake Erie John Doe

December 2022

In the final episode of our 2022 Case Studies: Part 2 mini season, Just Science sat down with Dr. Thomas Gilson, Dr. Harmeet Kaur, and Hristina Lekova with the Cuyahoga County Medical Examiner's Office to discuss a puzzling case in which the identity of a decedent from 2014 still remains unknown. Since 2011, it has been uncommon for the Cuyahoga County Medical Examiner's Office to have a case in which a decedent remains unidentified for an extended period of time.

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...

The National Missing and Unidentified Persons System (NamUs) is a national centralized repository and resource center for missing, unidentified, and unclaimed person cases across the United States. NamUs helps investigators match long-term missing persons with unidentified remains to resolve cases and bring resolution to families.

Forensic Use Of GPR And LiDAR Technology For Clandestine Grave Detection

April 2024

Following a multi-month course of data collection using simulated human gravesites, Ground-Penetrating Radar (GPR) researcher Jordan Mullikin will discuss the advantages and disadvantages of GPR for the detection of unmarked graves. Additionally, this webinar will explore Light Detection and Ranging (LiDAR) technology for the same purpose and investigate the potential integration of both technologies for optimal detection of clandestine graves within the law enforcement and forensic communities.

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...
