Welcome to episode 132 of FBI Retired Case File Review with Jerry Williams.

I'm a retired agent writing crime fiction inspired by

true crime FBI cases. Today we get to speak to retired agent Dan Kraft who served in the FBI for 31 years.

During his Bureau career, he was assigned primarily to violent crime investigations and was trained as a criminal profiler and polygraph

examiner. In this episode, Dan Kraft reviews his investigation of Jeffrey Dahmer, who he interviewed on four separate occasions

each time developing a comprehensive behavioral profile of the serial killer.

Dan Kraft also provides tips for interviewing violent criminals.

He has been designated by the FBI as a master police instructor and has created and

taught an advanced interview interrogation course at the FBI Academy in Quantico.

He has trained law enforcement personnel on investigating street gangs,

terrorism, police-related critical incidents, reading a crime scene, crime scene analysis, sex-related

crimes, stress management, and a variety of interview and interrogation hostage negotiation courses.

He is also taught at Marquette University in Milwaukee at Metropolitan State University

and Concordia College in St. Paul, Minnesota.

Jeffrey Dahmer. I never want to be exploitive just the thought of having that

again. So when it gets to that part, it's at at the end you may want to fast forward.

But before we get to the interview just a few quick things.

First of all I was able to finally connect with firefighter Joan 77 who claimed her it's a boy it's a book
