Dennis Rader, better known as the BTK Killer – standing for “bind, torture, kill” – is one of America’s most infamous serial killers.
He stalked the city of Wichita, Kansas, terrorizing its people for over 30 years before being finally caught, during which time he managed to live a seemingly ordinary life as a church leader, husband, father, and compliance officer. Behind that veneer was a sadistic killer with black sex fantasies, who sent menacing messages to the police and press, thinking he was cleverer than all those trying to apprehend him.
From 1974 through 1991, Rader murdered at least ten individuals, the majority of them women, in a string of sadistic crimes characterized by domination, strangulation, and psychological brutality. He dubbed himself BTK – an ominous acronym for “Bind, Torture, Kill” – and for many years, authorities grappled with uncovering the face behind the letters that terrorized Wichita.
Following his 2005 arrest, Rader exposed the chilling dual nature of his personality – the upstanding family man by day and the ruthless killer by night. “How could a guy like me, church member, brought up a family, go out and do those kind of things?” Rader explained to a reporter. “It’s a dark side of me.”
The Making of a Killer
Dennis Lynn Rader was born in March of 1945 in Wichita, Kansas. The oldest of four children, he seemed to have a normal childhood. Shy and reserved, he enjoyed comic books and playing outside. But behind that quiet face was something more sinister.
Later, Rader described how, when he was a boy, he had witnessed a chilling moment when his mother’s ring became caught in the spring of a couch, holding her. Rather than assist her right away, young Dennis experienced a thrill – a warped satisfaction at seeing her trapped. It was then that he said he began to indulge in the fantasies that would consume his adult years.
Already by grade school, Rader was fantasizing about bondage situations and had created early erotic fantasies centered on control and pain. As an adolescent, he experimented with strangulation and started to kill animals for kicks. He admired other killers such as Harvey Glatman, who bound and killed his victims.
In spite of all these violent impulses, Rader was outwardly completely normal. Having served in the U.S. Air Force, then later obtaining a degree in criminal justice from Wichita State University, he married Paula Dietz in 1971. They had two kids and were very active church members. But when he was laid off at Cessna, his pent-up darkness flared once again — and the BTK Killer was born.
The Murders Begin
Rader’s rampage began on January 15, 1974, when he brutally murdered the Otero family. Convinced that the mother, Julie, was at home with her two children, he broke in without knowing that her husband was also at home. He tied up the family, murdered them one after another, and hanged their 11-year-old daughter, Josie, in the basement before he left.
After that, the murders went on. He killed Kathryn Bright in that same year, stabbing her repeatedly. In 1977, he strangulated Shirley Relford after stalking her home and then killed Nancy Jo Fox.
Rader paused his killings for several years before returning in 1985 to murder his neighbor, Marine Hedge. He strangled her and then took her body to his church, photographing her corpse in bondage positions. The following year, he killed Vicki Wegerle after gaining entry to her home by pretending to be a phone company worker.
His last confirmed victim, Dolores Davis, was murdered in January 1991. Rader broke into her house, bound her, and strangled her before leaving her corpse on some countryside.
Law enforcement believes Rader is connected to other cold cases, such as the murders of Cynthia Dawn Kinney and Shawna Beth Garber, after police discovered “items of interest” at his former residence in 2023.
A Double Life and Years of Taunts
During his years as BTK, Rader was unbreakably ordinary. He worked for ADT Security Services, putting in home alarms for customers who were frightened of him — ironic, since he was the very thing they feared to escape.
He was also president of his church council and captain of the local Cub Scouts troop. To his wife and kids, he was stern but loving. None of them knew they shared their home with a serial killer.
But Rader craved notoriety for his crime. Between 1974 and 1979, he wrote boastful letters to newspapers such as The Wichita Eagle and television stations, gloating over the killings and taunting police for their failure to apprehend him. He signed them “BTK” and demanded publicity: “How many do I have to kill before I get a name in the paper?
His communications suddenly ceased during the late ’70s, and detectives eventually labeled the BTK case cold.
The Digital Blunder That Revealed Him
Three decades since the Otero killings, Rader’s ego was what brought him down. In 2004, he resumed his communications, mailing a letter to The Wichita Eagle including a driver’s license and crime scene photographs of victim Vicki Wegerle – evidence which directly linked her murder to BTK for the first time.
Rader deposited more packages in the Wichita area with notes, sketches, and even dolls wrapped in rope. In one of them, he inquired of police whether it would be possible to trace a floppy disk back to him. Detectives, realizing this might be the break they needed, responded publicly that it was okay. Rader fell for the trap.
The floppy disk he mailed to a TV station in the local area was his downfall. Investigators extracted erased metadata indicating it had been accessed at “Christ Lutheran Church” by “Dennis.” When they followed the car captured in surveillance video from an earlier BTK drop point to Rader’s residence, it all fell into place.
A DNA test from his daughter’s medical history established the connection. Dennis Rader was arrested on February 25, 2005.
Conviction and Life in Prison
Rader was indicted on ten counts of first-degree murder. In June of 2005, he matter-of-factly pleaded guilty to all the charges, recounting each murder in vivid detail with no emotion. “It’s just something I did,” he informed the court.
That August, Rader was sentenced to ten consecutive life terms – one for each known victim – with no chance of parole, as Kansas did not have a death penalty then. He is still in prison at the El Dorado Correctional Facility, housed in a small cell with restricted privileges.
In recent years, limitations on his activities have loosened somewhat as a result of good behavior, and he has been permitted to read, draw, and watch television. His daughter, Kerri, however, says the man she loved is now “rotting to his core.”
In 2023, after nearly two decades apart, she visited him to assist investigators with new cases. “It took him a minute to process who I was,” she told News Nation. “He’s lost inches, he’s frail, and for the first time, he dropped his mask and became BTK in front of me.”
