Listen, as long as Dr.

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.

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.

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.

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.

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.

In episode two of our Case Studies Part 2: mini season Just Science sat down with Jason Moran, commander of police at the Cook County Sheriff's Office, to discuss how he and his colleagues set out to identify the remaining victims of John Wayne Gacy, decades after their bodies were found. Technological limitations can sometimes make it very challenging to identify decomposed human remains. In the case of serial killer John Wayne Gacy, eight of his 33 victims remained unidentified for more than 30 years.

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 pathologist and medical examiners can be used in conjunction with other disciplines, such as bloodstain pattern analysis, to provide pivotal information about a case.

In episode four of our Case Studies: Part 1 mini season, Just Science sat down with Leighton D'Antoni, the Assistant District Attorney in Dallas County, Texas, to discuss how forensic genetic genealogy was used as an investigative tool to help solve a series of violent cold cases. In the 1980s, several violent sexual assaults occurred in Dallas County, Texas and Shreveport, Louisiana. These cases were all linked by a foreign DNA profile; however, no suspect was found and the cases went cold.

In episode three of our Case Studies Part one mini season, Just Science sat down with Dr. Sharon Moses, an Associate Professor of Anthropology at Northern Arizona University, to discuss forensic archeology and locating victims of no-body homicides. Forensic archeologists can play a critical role in body recovery and search strategies for locating human remains because homicide offender’s choices and body disposal sites are influenced by various social and environmental factors.

In episode two of our Case Studies Part 1 mini season Just Science sat down with Stacey Chepren, member of a trial team for prosecuting federal criminal misconduct cases to discuss a fatal pedestrian hit and run involving trace and digital evidence. On a quiet morning in the city limits of Las Vegas, a pedestrian in a well-lit crosswalk was struck by an impaired driver who left the scene. There were no witnesses, but authorities quickly pieced together the case through a vehicle's aftermarket paint job and neighborhood video footage.

In episode one of our Case Studies Part 1 mini season, Just Science sat down with Michael Fagert, a certified latent print examiner at the Kansas Bureau of Investigation, to discuss a latent print phenomenon that is not often seen in casework. There are very few instances of identifiable fingerprints on cartridge cases recovered from crime scenes, as the firing process introduces adverse physical and thermal stressors to fingerprint residues.

In part two of the final episode of our Strengthening the Forensic Workforce Season, Just Science continued the conversation with Dr. Peter Stout, Dr. Ray Wickenheiser and Matthew Gamette discussing the future of the forensic workforce. FEPAC accredited institutions provide high quality forensic science education for undergraduate and graduate students.
