There is almost NO category of crime that DeBardeleben didn't at least dabble in. I hope it's a decent chunk of new text in the updated version, because no amount of information added to this story could be too much for me. It's clear that not only did DeBardeleben want to hurt his victims in the present, but that he took great pride in going out of his way to make sure his victims STAYED hurt years after he disappeared from their lives. Then you remember this guy was free to do this for decades, and it becomes overwhelming to the point where your brain wants to go into denial mode just to lessen the horror. I can't help but think it's due, at least in part, to a conscious effort on behalf of the Secret Service to keep a lot of this story quiet. The fact that DeBardeleben's name isn't even close to being as well-known as Bundy, Dahmer, Gacy and the rest of the most infamous names in serial crime is incomprehensible to me. When Roy Hazelwood himself makes special mention of how absolutely vile a person he is, you know DeBardeleben has reached a level of absolute depravity and corruption that is extraordinary even among the worst of the worst criminals. The depth and breadth of his narcissism and sexual sadism is almost unrivaled compared to other serial offenders I've read about. Despite all the holes in the timeline, what parts of DeBardeleben's life we are told about are absolutely chilling. That someone so toxic could cover so much ground in so little time is nauseating, because it forces you to imagine how many men, women and children he could've victimized in just a single year of his criminal career. This book has three significant problems, most of which stem from the sheer complexity of the case itself: I read true crime books in order to get inside the heads of the offenders, and I felt like this book had only barely scratched the surface of DeBardeleben's inner turmoil and pathology by the time it was over. But more on that in a bit. Before I read this I knew only a tiny amount about DeBardeleben, but one thing I did know was that the Secret Service was aware of his existence as a sexual predator years before he was apprehended as the Mall Passer, and that very little if anything was done to investigate further or even question him about it. He tortured others in every way imaginable and in fact seemed to view torture as an art, one he researched and practiced and was exceedingly skilled at. While the Secret Service and DeBardeleben himself kept extensive records, there are still a staggering number of gaps in his crime timeline, which no one aside from DeBardeleben himself seems able to fill in.
