The August 1985 FBI Bulletin that Bundy praised in his correspondence with Keppel

 

I have found a link to the August 1985 FBI Bulletin, which reported findings of a study on serial murders: "Their (the 36 subjects studied) visual interests (pornography, fetishism, and voyeurism) reinforced the sex and aggression” (pg 5).

Bundy himself referred to this very FBI Bulletin in his March 4, 1986 letter to Keppel, commenting that for the serial murderer, one form of voyeurism is watching a movie of someone committing serial murder. And Bundy was also suggesting that the police hold a serial murder movie festival, as a proactive tactic to attract voyeurs, sexual sadists, porn addicts who might be committing homicide...

Bundy’s own March 4, 1986 letter to Keppel is transcribed in the book “Reflections on Green River: The Letters of, and Conversations with, Ted Bundy" by Sara A Survivor.

During his imprisonment at Florida State Prison, in the years preceding his execution, Bundy had been reading several FBI law enforcement bulletins. He seemed very interested in the information that the FBI presented there, because it was speculations about what might have been going on in a serial murderer's mind, during and after a crime and how did he purge the crime scene... In the 80's the FBI bulletins talked a lot about the organized crime scene versus the disorganized crime scene and all those things which made a lot of sense to Bundy. Bundy also felt that the FBI bulletins showed that the FBI was attempting to get at the heart of the "why".

Bundy also mentioned that August 1985 FBI Bulletin in his February 22, 1986 in-person conversation with Keppel (Keppel went to visit him in prison and recorded their conversations and they are now transcribed and published in the book “Reflections on Green River")... Here is what Bundy told Keppel: "Well, just, I wish I'd brought that copy. It's occurred to me several times it'd be interesting to go over that with you, that particular summary that was in the law enforcement bulletin about the study the FBI did with those 36 persons. Because I think there's a lot of good information in there. I'll be very general and the fact that, let's face it, 36 is not a very good sample size and we don't know if it's representative, it's certainly probably not representative of the total population, if we can view it that way, the population of serial murderers who are on the streets today. And not identified and not in prison. And so any conclusion you draw from it would have to be taken with a grain of salt. You know, very tentatively viewed. And yet there was some very good stuff in there. I still think that like you say, your average detective may not understand what the FBI means by a disorganized personality and all those characteristics they associate in terms of background and present behavior and how that related to, may or may not, relate to a disorganized crime scene. And probably in my opinion, the real world does not lend itself to those neat kinds of characterizations anyway because any crime scene is probably going to be a mixture of various organized and disorganized kinds of aspects, characteristics that you know, that ultimately each investigator has to go on his instincts anyway. But I did think it was pretty good. They're on the right track. I mean, they're talking to the right people. They're trying to anyway. But they're up against some pretty formidable problems because, obviously not everybody accused of that kind of criminal behavior is going to talk to them. And even if they do there's a question whether they're going to be totally candid with them."

The study that Bundy was praising came out in a summary chapter form in the FBI journal. The FBI had interviewed 36 offenders apparently...

Bundy also told Keppel: "But, I'm not so sure that 36 is a very good number to -- especially with a variance. There seems to be quite a variance in the backgrounds of the M.O., the backgrounds in the offenders. And to generalize to what all or maybe future investigations should be might be kind of hazardous and I would certainly hope that most police officers would view everything with an open mind to the extent that they pursue all angles and not just hone in on one. Cause, you know, the FBI may be experienced and recognize organize and disorganized crime scenes, but the routine detective does not."
