John Douglas joined the FBI in 1970 and built something that did not exist yet: a way to read a crime scene backward, from the body to the mind that left it. He did it the hard way, walking into prisons to interview men no one else would sit with, and writing down what he learned so the next investigator could use it.
For 25 years he sat across a table from the worst people the country ever produced and kept his face still while they told him everything. He caught them by understanding them. A few he never put down.
Five stayed with him. One he would not even let other cops listen to. If the show Mindhunter felt familiar, this is the man underneath it.
Number five is the only man on this list who never killed anyone with his own hands: Charles Manson. He did not need to, because he got other people to do it for him.
That makes him harder to sit across from than a killer, because there is no crime scene to read. Just a man obsessed with control. Douglas knew that if he walked in and took charge, he would walk out with nothing. So he did the opposite.
Manson hated that others had control over him. Douglas, at 6-foot-2, was facing a man of about 5-foot-2, and he staged the interview environment whenever he could. He used very low lighting. He did not go in with notes or tape recorders, a mistake he made early on, because the people he was dealing with were extremely paranoid.
He watched Manson's moves and body language, all of them deliberate. He sat lower than Manson, so the smaller man was looking down at him. No notepad, because to a paranoid man a notepad is perceived as a weapon. Low light, so the room felt like Manson's room, not the FBI's.
Douglas handed over every signal of power he had, and the man across the table relaxed enough to talk. It was not respect. It was bait, and it worked, because Douglas always went in through the ego, never around it. He walked out with exactly what he came for.
Number four was screaming and swearing at him before the cell door even opened. His name was Richard Speck.
In one night in 1966, Speck walked into a Chicago townhouse full of student nurses and killed eight of them. One lived because she rolled under a bed and stayed there in the dark until morning. Speck was the kind of violent that fills a room with terror, and Douglas, instead of calming it down, climbed right into that terror.
Speck was about 6-foot-3 or 6-foot-4, an ugly man, violent as hell, screaming and yelling before the interview. Douglas wanted him to feel like he was in control. He used street language to describe the homicides, telling the counselor beside him that he did not know what Speck ate for breakfast, but that this guy was amazing for what he did with seven women.
It may sound terrible, but the goal was to get the man to talk back. Speck started saying he did not have sex with all seven. A man like Speck will never open up to respect. He opens up to someone who sounds terrible like him, and it worked.
Speck even started correcting him, feeding him additional details. Then Douglas said the thing he never should have: that he knew it was just the one on the couch. Speck told him he was sick and should be in there with him, and they started laughing. A federal agent and a man who killed eight women in a single night laughing together in a cell, because the laughing was the tool that kept him talking.
That is the job. You become whatever the other man needs, and you carry home what it costs you.
Number three is the one true-crime audiences always come for: Ed Kemper. He stood 6-foot-9, weighed close to 300 pounds, and had an IQ in the genius range. He killed 10 people, including his own mother.
Unlike almost anyone else on this list, he actually wanted to talk. That made him the most useful man Douglas ever interviewed and one of the most dangerous rooms he ever sat in at the same time, because Kemper knew exactly how to dominate and fill that room.
His mother told him he could never date the women at the university where she worked. Those became his initial targets. He picked up hundreds of them until he started selecting certain ones to kill.
Students at the university were told to go with a car if they saw a university sticker on it. His mother worked at the university and had a university sticker, so he used the car. It finally culminated when he had enough of her and killed her with a ball-peen hammer, decapitated her, and then killed a neighbor, a good friend of his mother's.
The crimes were about anger, power and manipulation, because this big guy felt like an inadequate nobody. During the interview, Douglas even had to forcefully tell him to shut up and just answer the questions.
For men like Kemper, their accomplishment in life is that particular crime, and it is like a CD in their brain. Once you turn that CD on, it is remarkable how they remember every specific related to the crime. You really could not shut them up.
When Kemper talked, he handed Douglas something no textbook ever could: the mechanics of it all, how he chose his victims and how he got a stranger to trust him long enough to get into the car. He was so menacing that when the girls came out and looked in, he would make it appear he was on his way to an appointment by glancing at his watch. They would feel relieved that it was safe to go with this guy, because he had an appointment he had to make.
Kemper described pulling to the curb and glancing at his watch like a man late for something. That was the whole trick. A young woman decided he was safe enough because a dangerous man would not be in a hurry to be anywhere. Kemper turned the most ordinary gesture in the world into a lure, and Douglas kept that detail, which later helped him catch men Kemper never met.
Kemper has been eligible for parole for years, and every time he refuses to leave. He says he is not ready, and Douglas read that as the most honest thing Kemper ever told him.
Number two is the case that put profiling itself on trial in front of the entire country, and even after that, it is the one he still will not let anyone hear. Number two almost ended him. It is Wayne Williams, the man known for the Atlanta murders.
Between 1979 and 1981, Atlanta was burying its children, and the whole investigation was under a spotlight the profiling world had no template for. Douglas walked in and said out loud what nobody in the room wanted to hear about who they should be hunting, and it made him enemies fast.
He described the suspect's race, age, kind of car, kind of criminal history and marital status. People magazine came to his office and interviewed him about it, and he was asked who had approved the interview. He had.
At one crime scene, a child killed at a school, a cop came up to him and said he had seen the profile and called it a bunch of nonsense. Douglas told him he had not asked to be there and just wanted to get back to Quantico, where he had tons of cases.
He also said something controversial: that the cases were all linked together by one offender. He felt the bodies would end up in water, so investigators started staking out the Chattahoochee River. About the third day, bodies were found in the water. They went up on a bridge and there was Williams.
Then, Douglas believed, they really screwed up, including the bureau. They should have had enough to bring him back to the office, but they let him go even though they saw ligatures in the car. They surveilled him for days before finally bringing him in.
The prosecution was losing. Douglas was observing and predicting certain things that might happen. An attorney named Gordon Miller asked him what was up, and Douglas said that one week from today Williams was going to get sick in the courtroom. It would be an edge and a sympathy ploy.
Douglas was basically being kicked out for what he had said the day before, and a plane was waiting for him. Then Wayne Williams got sick in the courtroom and was taken away to the hospital. Douglas believed he was feigning it.
Douglas had profiled more than the crimes themselves. He had profiled the suspect and predicted Williams would crack on the stand under one specific kind of pressure. The defense bet the opposite, holding Williams' soft hands up to the jury and asking if those looked like the hands of a serial killer, leaning on the exact myth Douglas spent his life tearing down: that a monster has to look like one.
Douglas coached the prosecution on what to do, how to act and what to say. He coached another attorney, Jack Malloy. When Malloy held Williams' hands on the stand, he was to say in a low voice, low enough for the jurors to hear, asking how it was when he wrapped his fingers around Terry Pews' throat, and whether he panicked.
Williams answered no, then caught himself, saying he knew they had that FBI profiler in the court trying to get him to fit that profile. The jurors were looking at him. Williams was later convicted of two adult murders and formally linked by authorities to many of the child killings, though he was never convicted of those.
Williams is number two because this was the case that proved a profile could hold up with the whole country watching, and it nearly cost Douglas everything to win it.
Number one is the one he calls the worst, not anyone else's word, his. Of every man John Douglas sat across from in 25 years, there is one he calls the worst without ever being asked, not once but twice, in two separate interviews years apart.
Number one carries two names this time: Lawrence Bittaker and Roy Norris. Bittaker and Norris were two rapists serving time in prison for rape. Their fantasy was that when they got out, they would rape a teenager for every year of a teenager's life, from 13 to 19 years of age. They got a vehicle they called the Murder Mack, an insulated van.
They are also known as the Toolbox Killers, a name that reflects their use of items like pliers, ice picks and hammers to torture teens, often hitchhikers they had abducted. They first met in prison in California in 1977. Bittaker had been convicted of assault with a deadly weapon, and Norris was serving a sentence for rape.
While behind bars, they bonded and planned out loud what they would do when they got out. When they were released, they did it to a series of young women in Southern California in a van they had soundproofed on purpose.
By January 1979, both men had been released from prison, which is when they purchased the insulated van. In June 1979, they kidnapped 16-year-old Lucinda Schaefer. The following month they abducted 18-year-old Andrea Hall. Their next two victims were 15-year-old Jackie Gilliam and 13-year-old Jacqueline Law, taken together in September of that year.
Bittaker and Norris drove these teens into nearby mountains where they had scoped out fire roads for privacy for their crimes. There they not only raped and murdered their victims, but also used everyday toolbox items to torment them. Schaefer was strangled with a wire coat hanger tightened with pliers, and Hall and Gilliam both had ice picks stabbed into their ears, which is how they got the Toolbox Killers name.
Douglas later interviewed Lawrence Bittaker at San Quentin State Prison after Bittaker and Norris were captured and convicted in the early 1980s. There was also an audio tape of the torturing of the victims, which Douglas described simply as terrible.
Douglas brought a female agent in with him for the interview. Every time she would ask a question, Bittaker never looked at her. He always looked at Douglas. At some point they started talking and Bittaker started crying, welling up and getting emotional.
Douglas thought to himself that he had just gotten hardened, that Bittaker was crying because his life was ruined, because he would spend the rest of his life in prison, but that he did not really give a damn about the victims' lives he had taken and stolen. During the interview, Douglas would never let on that he felt that way or talked that way.
Even after that, Douglas kept his face still. He finished the interview and then he took it home, and it never left him since. These men are ranked at number one because the man who ranked killers for a living ranked this one himself.
Looking back at the five, it was never about the body counts. Manson was the one he beat. Speck was the one who taught him what the job costs. Kemper was the one who handed him the manual. Williams was the one who put Douglas's whole method on trial. And then there were the two he still will not let anyone hear.
Every one of them taught Douglas something he then used to catch the next one. That was the trade. He learned to see it coming, and the price was that he could never stop seeing it. He went to work in the dark and came back home in the dark, dreaming about the cases he could not put down.
He also built the language the entire world now uses to talk about killers, and he paid for it slowly, one interview at a time.
