About this episode
Exploring the hidden motives and inner lives behind infamous cases, one cinematic story at a time.
0:00
Dennis Rader, president of the Christ Lutheran Church council, was meticulous about his work.
0:08
Every detail mattered.
0:10
He sits in his office in Park City, Kansas.
0:14
A municipal compliance officer.
0:16
A man who measures the height of grass and issues citations for junked cars.
0:23
It’s February, 2005.
0:25
Outside, the world sees a civil servant.
0:28
A husband.
0:29
A father.
0:30
A man you could trust.
0:32
Inside this room, he is finishing a project.
0:36
He takes a purple one-point-four-four megabyte Memorex floppy disk...
0:42
and slides it into a padded envelope addressed to a local Fox affiliate, KSAS-TV.
0:49
He is re-establishing contact.
0:52
He is re-asserting control.
0:54
He feels the familiar thrill, the godlike power he hasn't felt in years.
1:01
He has no idea he is mailing his own death sentence.
1:05
For thirty years, a shadow had a name in Wichita.
1:10
B-T-K.
1:10
Bind.
1:11
Torture.
1:11
Kill.
1:12
He gave himself the name.
1:14
Sent it in a letter tucked inside an engineering textbook at the public library in 1974, just months after his first...
1:24
project.
1:25
The Otero family.
1:27
Joseph and Julie, and two of their children, Josephine and Joseph Junior.
1:33
He talked his way into their home by saying his car had broken down.
1:39
He was polite.
1:40
He was calm.
1:41
He was a monster wearing a man's face.
1:45
He cut the phone lines.
1:47
And then he began his work.
1:49
Wichita held its breath.
1:51
The fear was a physical thing, a change in the air pressure.
1:57
People bought new locks.
1:59
They bought guns.
2:00
They looked at strangers with suspicion.
2:04
And sometimes, the man they hired to install their new ADT security system...
2:11
was Dennis Rader.
2:12
He walked through their homes, pointing out vulnerabilities, selling them peace of mind while he catalogued their entry points in his mind.
2:25
He was a Cub Scout leader.
2:27
He was the man who passed the collection plate on Sunday.
2:32
He was hiding in the one place no one ever thinks to look.
2:37
Plain sight.
2:38
He killed seven people between 1974 and 1977.
2:42
Then, silence.
2:43
For a while.
2:44
He struck again in ‘85.
2:46
Again in ‘86.
2:48
Again in ‘91.
2:49
And then… nothing.
2:50
For thirteen years, the shadow receded.
2:54
The city began to believe he was dead, or imprisoned for some lesser crime.
3:00
The letters stopped.
3:02
The killing stopped.
3:04
The fear subsided into a grim local legend.
3:08
But Dennis Rader wasn't gone.
3:10
He was just… busy.
3:12
Raising his two kids.
3:14
Going to church.
3:15
Getting promoted.
3:17
Living a life so crushingly normal, so profoundly boring, it was the perfect camouflage.
3:25
He kept his trophies—drivers licenses, photographs, souvenirs from his projects—in a locked file cabinet.
3:34
He was just waiting.
3:36
His ego, the engine of his entire secret life, was starving.
3:41
It needed to be fed.
3:43
In 2004, the thirtieth anniversary of the Otero murders, he couldn't stand it anymore.
3:50
He began sending letters again.
3:53
Mementos.
3:54
A victim's driver's license.
3:56
Photos.
3:57
He was taunting the police, playing a game only he understood.
4:02
He was a master, and they were his audience.
4:06
And then he made a fatal, arrogant mistake.
4:10
He wanted to know if his communications could be traced if he used a floppy disk.
4:17
So, in a coded message, he simply… asked them.
4:21
"Can I communicate with you on a floppy and not be traced to a computer.
4:28
Be honest." Lieutenant Ken Landwehr of the Wichita Police Department saw the opening.
4:35
The monster was talking.
4:37
And he was asking for help.
4:40
Landwehr decided to lie.
4:42
He placed a classified ad in the Wichita Eagle.
4:46
A simple message.
4:48
"Rex, it will be OK." It was the signal.
4:51
You can trust us.
4:53
So Dennis Rader trusted them.
4:55
He went to his church.
4:57
He used the computer there to copy files onto the disk.
5:02
He thought he was being clever.
5:05
He deleted the document he’d been working on, a letter to the news station.
5:12
He thought that was enough.
5:14
He didn't know about metadata.
5:17
He didn't know that even a deleted file leaves a ghost.
5:21
A digital fingerprint.
5:23
When the forensics team at the KBI lab examined the disk, they found it.
5:30
The ghost.
5:31
A fragment of a Microsoft Word document.
5:34
And in its properties, two words.
5:37
Last modified by: “Dennis.” Location: “Christ Lutheran Church.” In the squad room, it was like a switch being thrown.
5:48
Decades of dead ends, of false leads, of crushing frustration...
5:53
suddenly illuminated by a single, blinding light.
5:58
Christ Lutheran Church.
6:00
They checked the church council leadership.
6:03
The president...
6:05
was a man named Dennis Rader.
6:07
They ran his name.
6:09
And it all came together.
6:11
His truck, a black Jeep Cherokee, had been spotted near the drop sites.
6:17
The knot in his writing matched the knots used in the murders, a knot he would have learned as a boy scout.
6:27
The quiet compliance officer.
6:30
The church president.
6:31
The family man.
6:33
It was him.
6:34
The arrest was almost anticlimactic.
6:37
They pulled him over near his home during his lunch break on February 25th, 2005.
6:44
No chase.
6:45
No shootout.
6:46
Just a quiet man in a car.
6:48
"Mr.
6:49
Rader," the officer said, "I think you know why we're here." And in that moment, the carefully constructed world of Dennis Rader simply ceased to exist.
7:02
At the station, he didn't ask for a lawyer.
7:06
He asked for a glass of water.
7:09
For seventeen hours, he talked.
7:11
He wasn't confessing.
7:13
He was lecturing.
7:15
He corrected detectives on dates, on the names of his victims, on the specific details of their last moments.
7:24
He called them his projects.
7:27
When describing the murder of one of his victims, he didn't say he killed her.
7:34
He said he had to "put her down." There was no remorse.
7:39
No emotion.
7:40
Only the cold, clinical pride of a craftsman describing his work.
7:45
His daughter, Kerri, was at work when the FBI showed up.
7:50
They told her her father had been arrested.
7:54
She thought it was a mistake.
7:57
A joke.
7:57
Then they told her why.
7:59
And the man she knew—the dad who took her fishing, who taught her how to drive, the man who was her hero—was erased.
8:10
Replaced by a stranger.
8:12
A monster.
8:13
The duality wasn't a mask he wore.
8:16
There were two people living in that one body.
8:20
The world only saw the one he wanted them to see.
8:24
And in the end, it was the monster who wanted to be seen.
8:29
He just couldn't stand being ignored.
8:32
He needed the world to know his name.
8:36
And for that, he gave them everything they needed to take his world away.
8:42
The man who terrorized a city for three decades wasn't brought down by a brilliant detective or a lucky break.
8:52
He was brought down by his own ego, and a single, deleted file on a purple floppy disk.
