Profiling

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?

NIJ scientist Tracey Johnson joins science writer Sarah Michaud in this episode. They discuss Rapid DNA technology, and Tracey explains the complexities of this technology – its pitfalls and its possibilities.

Technological advances have made it possible to detect male DNA in evidentiary samples collected several days after a sexual act has taken place. Panelists will present the research that has led to these findings, followed by a discussion of the potential impact of this work from the perspectives of the sexual assault nurse examiner (SANE) and the crime laboratory communities.
