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.

Just Facial Recognition for Forensic Investigations

November 2023

On episode six of our case study season. Just Science sat down with Dr. Richard Vorder Bruegge, senior physical scientist at the Federal Bureau of Investigation, to discuss how facial recognition technology was used to help identify individuals in photographs and two landmark cases. Many individuals encounter facial recognition technology in their everyday lives, like when they unlock their phones. The same technology can significantly speed up and improve forensic investigations. Listen, along is Dr. Vorder Bruegge describes how pattern based matching is used to compare faces and images.

Just Forensics in the Digital Age

November 2023

Associates, Inc., to discuss utilizing digital evidence in real world cases. In the digital age forensic technology has broad applications for investigations from cell phones, social media accounts and car infotainment system data to three dimensional modeling for crime scene reconstruction, technology is becoming a staple in forensics. Listen, as long as Dr.

Just Adding Value Using Voice Identification

October 2023

In episode four of our case study season, Just Science sat down with Josh Yonovitz, expert witness and forensic audio. To discuss the history of utilizing voice identification and investigations and the current state of forensic audio. In the 1960s, voice ID started being used in forensics, but the original voiceprint analysis used was proven to be inaccurate. Nowadays, forensic scientists use a methodology known as oral acoustic speaker identification, which is scientifically accepted but poorly understood.

Just Collecting More Evidence from Cartridge Cases

October 2023

In episode two of our Case Studies season, Just Science sat down with crime scene technician Brian Turner and Detective Roberto Caceres from the Broward County Sheriff's Office to discuss a new methodology for processing fired cartridge cases. When a cartridge case is recovered from a crime scene, investigators must typically decide whether to swab it for DNA or process it for latent prints.

Just Footwear Forensics to Further Investigations

October 2023

In episode three of our case study season Just Science sat down with Laura Matson an advanced latent print and footwear examiner in the Wisconsin State Crime Laboratories to discuss the value of providing footwear investigative leads. Footwear impressions are commonly found in crime scenes. However, these impressions can be difficult to detect and collect, which leads to the under-utilization of footwear evidence.

Just Investigating a No-Body Homicide in Canada
