Just Investigative Support For Indigenous Communities Feb 10, 2023

Show notes

In episode three of our Unidentified Human Remains mini season, Just Science sat down with Mark Pooley, founder of Native Search Solutions, and Dustin Driscoll, Research Public Health Analyst at RTI International, to discuss the many barriers faced by indigenous communities when it comes to identifying missing and murdered persons. In order to properly investigate cases of missing and murdered individuals, it is crucial that law enforcement agencies have access to necessary resources and technologies, including DNA analysis capabilities, national databases, and sufficient manpower. Unfortunately, many tribal law enforcement agencies currently work with limited access to these basic investigative tools, making it much more difficult to find and identify missing members of native and tribal groups. Listen along as Dustin and Mark discuss common causes of missing indigenous persons, specific gaps in investigative resources, and the growing community working to support indigenous groups. This episode is funded by the National Institute of Justice’s Forensic Technology Center of Excellence (Award No. 15PNIJ-21-GK-02192-MUMU).

Show notes

In episode two of our Unidentified Human Remains mini 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. Due to its quick turn-around time, rapid DNA technology has become a valuable tool that is used by law enforcement agencies, accredited crime laboratories, coroner’s offices, and the military. Listen along as Neal discusses the capabilities of rapid DNA analysis, cases in which rapid DNA analysis was used, and the importance of incorporating novel technologies within the field of forensic science.

Just Teeth And Technology Jan 26, 2023

Show notes

In episode one of our Unidentified Human Remains mini season, Just Science sat down with Dr. Kenneth Aschheim, Assistant Chief Forensic Odontologist 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 with antemortem dental records in order to help identify unknown human remains. Listen along as Dr. Aschheim discusses the process of forensic odontology, the benefits of using teeth alongside other methods of human identification, and using technology to advance the field.

Show notes

In the final episode of our 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. In the case of an unidentified body found in Lake Erie, forensic scientists have utilized techniques such as fingerprinting, DNA matching, facial reconstruction, and more, in attempts to give this individual his name back. Listen along as Dr. Gilson, Dr. Kaur, and Hristina discuss details of the Lake Erie case, the wide range of resources used for human identification, and the benefits of allowing medical examiners and forensic scientists to work in close proximity. This episode is funded by the National Institute of Justice’s Forensic Technology Center of Excellence (Award No. 15PNIJ-21-GK-02192-MUMU).

Just Autopsy Results And Crime Scene Reconstruction Nov 25, 2022

Show notes

In episode one of our Case Studies: Part 2 mini season, Just Science sat down with Kelly Ayers, an International Association for Identification certified Senior Crime Scene Analyst, to discuss how preliminary autopsy results can help investigators piece together a story of what happened at a crime scene. For crime scene investigators, preliminary autopsy results issued by forensic pathologists and medical examiners can be used in conjunction with other disciplines, such as bloodstain pattern analysis, to provide pivotal information about a case. For example, medical information about the injuries a victim sustained may help investigators determine the weapon that was used, or the sequence of events that occurred within the scene. Listen along as Kelly discusses how preliminary autopsy results may be used to alleviate unnecessary laboratory testing, add case context that can be used in court, and offers advice on effective communication while working a scene. This episode is funded by the National Institute of Justice’s Forensic Technology Center of Excellence (Award No. 15PNIJ-21-GK-02192-MUMU).

Just Labor Trafficking In The U.S. Oct 28, 2022

Show notes

In episode three of our Human Trafficking Research season, Just Science sat down with Dr. Rebecca Pfeffer and Dr. Kelle Barrick, both research criminologists at RTI International, to discuss the importance of labor trafficking research as a specialized field within the broader scope of human trafficking. Labor trafficking cases can be difficult to identify and are thereby often overlooked and underfunded. Due to key differences between labor trafficking and other forms of human trafficking, it is important to independently investigate best practices for prosecution, resource allocation, and response to labor trafficking. Listen along as Dr. Pfeffer and Dr. Barrick define labor trafficking, discuss myths and misconceptions, and identify differences between labor trafficking and sex trafficking. This episode is funded by RTI International’s Justice Practice Area.
