In this Justice Today podcast, NIJ Social Science Analyst Eric Martin discusses NIJ's support to law enforcement dealing with serial killer investigations, and answers questions about specific cases and serial killers in general.


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?

Mark Greene, the Director of the Office of Technology and Standards at NIJ, and Lucas Zarwell, the Office Director of NIJ’s Office of Investigative and Forensic Sciences, co-host this conversation about serial killers.
