Just Facial Recognition for Forensic Investigations
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.
Body Fluid Identification and Classification
In the first installment of the 20230R&D Webinar Series, Dr. Sarah Seashols Williams from Virginia Commonwealth University, demonstrates the ability to classify body fluids using miRNA expression from DNA extracts with 92% accuracy, eliminating the need for RNA extraction, greatly reducing evidentiary sample consumption and processing time in forensic laboratories.

Just Adding Value Using Voice Identification
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 Footwear Forensics to Further Investigations
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.
TOF/QTOF Mass Spec for Identification, Screening & Confirmation in Forensic Toxicology & Chemistry, Part I
In this specialized workshop intended for forensic science service providers (FSSPs), we explore the increasing adoption of Time-of-Flight and Quadrupole Time-of-Flight Mass Spectrometry (TOF/QTOF-MS) technologies within forensic laboratories. The session provides an in-depth examination of various critical stages, encompassing planning, validation methodologies, analytical techniques, data review processes, and report generation. Subject matter experts disseminate knowledge and share first-hand experiences related to the utilization of TOF/QTOF-MS technology.

Just Collecting More Evidence from Cartridge Cases
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 Investigating a No-Body Homicide in Canada
In episode one of our Case Studies season, Just Science sat down with Ian Oxton, Forensic Identification Specialist for the Calgary Police Service to discuss a triple homicide case involving the longest lasting Amber Alert in Alberta Canada's history. Operation Amber started as a race against the clock for a missing child, and his grandparents then quickly evolved into a massive search effort on a 40-acre property.

Cold Cases and Serial Killers, Part 1
In April 2018, the Golden State Killer, Joseph DeAngelo was arrested. NIJ support helped lead to his arrest, and in the aftermath of the arrest, NIJ Social Science Analyst Eric Martin was among those tasked with finding other cases NIJ helped law enforcement solve. Eric joins the show to talk about some of those cases, and answer some broader questions about serial killers: What is a serial killer? Are they on the rise? How do we know how many serial killers are currently active?
DART-MS For Seized Drug Analysis: Data Analysis (Session 2)
Direct Analysis in Real Time Mass Spectrometry (DART-MS) is a powerful analytical technique that allows for rapid detection and characterization of a wide range of compounds, including seized drugs. Over the last ten years, the DART- MS has slowly gained in popularity in crime labs due to its ability to provide rapid, reliable results with minimal samples preparation. Despite these advantages, DART-MS remains underutilized due to cost, data interpretation and familiarity with the technology.
