NIJ Social Science Analyst Eric Martin discusses why the number of serial killers is declining and the factors that deter people from this type of violent offense. He also shares insight into whether society is experiencing an evolution away from serial killing and how NIJ continues to support research in this area.

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

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 Director Dr. Nancy La Vigne joins the show to interview Dr. Marie Garcia, Director of NIJ’s Criminal Justice Systems Division and a former NIJ graduate research fellow. They discuss the application process, Marie’s experience as a fellow while at Temple University, and advice for future applicants.
