The Double Life: How a Church-Going Dad Hid a Monstrous Secret for 31 Years True Story Behind My Father the BTK Killer
The day her world shattered began with an ordinary knock at the door. The man on the other side would reveal a truth so horrible it would make her question every memory, every moment, every ounce of her identity.
Few stories in the annals of true crime are as chillingly paradoxical as that of Dennis Rader, the BTK Killer who terrorized Wichita, Kansas for decades. This is the story of a man who built a public life as a devoted family man, all while secretly committing some of the most brutal murders in American history. But beyond the gruesome details of his crimes lies an even more compelling narrative—that of his daughter, Kerri Rawson, who discovered at age 26 that the father she loved was a monster hiding in plain sight .
The Man Behind the Mask: Dennis Rader’s Ordinary Exterior
To his neighbors, friends, and family, Dennis Rader embodied normalcy. He presented himself as a devoted family man married to his wife Paula since 1971, and father to two children . He was a church congregation president and former Cub Scout leader, actively involved in his community . Professionally, Rader worked as a compliance officer in Park City, Kansas, and had previously spent years working for ADT Security Services, where he ironically installed security systems for homeowners fearful of criminals like himself .
This carefully constructed facade of normalcy was so convincing that even those closest to him never suspected anything was amiss. Rader’s family knew him as a mild-mannered man who built treehouses for his children, taught his daughter to fish, and treated her “like a tomboy,” letting her participate in whatever he was doing . Behind this ordinary exterior, however, lurked a deeply disturbed individual who had harbored sadistic sexual fantasies about torturing “trapped and helpless” women since childhood and had exhibited zoosadism by torturing, killing and hanging small animals .
The Reign of Terror: BTK’s Crimes (1974-1991)
Rader’s killing spree spanned from 1974 to 1991, during which he murdered ten confirmed victims in Wichita and Park City, Kansas . The moniker “BTK” stood for “Bind, Torture, Kill,” which described his signature method of committing crimes . He typically targeted women, invading their homes and attacking them there, often using household items to bind them before suffocating or strangling them .
Timeline of BTK’s Known Murders
- January 15, 1974: Rader commits his first murders, killing four members of the Otero family: Joseph Otero (38), Julie Otero (33), and their two children Joseph Jr. (9) and Josephine (11) . The children’s bodies were discovered by their older siblings returning from school . In a particularly chilling detail, Rader later confessed to hanging 11-year-old Josephine in the basement and masturbating as he watched her struggle on the rope .
- April 1974: Murders Kathryn Bright (21), who was also a Coleman Company employee like Rader and Julie Otero . Her brother Kevin was also attacked but managed to survive .
- March 1977: Kills Shirley Vian, locking her three young children in the bathroom during the murder .
- December 1977: Murders Nancy Fox . Following this killing, Rader grew irritated by the lack of media coverage and sent a letter to a local TV station demanding, “How many people do I have to kill before I get a name in the paper or some national attention” .
- 1985-1991: After his children were born, Rader’s murders slowed down, with him later telling his daughter he “got busy raising kids” . He nevertheless killed three more victims during this period: Marine Hedge (1985), Vicki Wegerle (1988), and Dolores Davis (1991) .
Rader’s pattern involved taking souvenirs from his victims, often stealing underwear, driver’s licenses, and other personal items . Though semen was found at crime scenes, autopsies revealed that none of the victims had been sexually assaulted in the conventional sense—Rader’s sexual satisfaction came from the act of binding and killing itself .

The Cat-and-Mouse Game: BTK Killer’s Communication with Media and Police
What set BTK apart from other serial killers was his obsessive need for recognition and notoriety . He initiated a series of taunting letters sent to police and media outlets, describing his crimes in detail and proudly referring to himself as BTK . His first communication came approximately nine months after the Otero murders, when he left a letter in a book at the Wichita Public Library claiming credit for the killings and promising more, signing it with his infamous “Bind, Torture, Kill” signature .
After a thirteen-year hiatus in communications between 1979 and 2004, Rader unexpectedly resurfaced, sending letters and packages that would ultimately lead to his downfall . This resurgence coincided with the 30th anniversary of his first murders and the impending publication of a book about the killings, suggesting his narcissistic need to recapture the spotlight .
The Downfall: How BTK Killer Was Finally Caught
Rader’s arrest came not through traditional police work alone, but through a fatal mistake driven by his enormous ego. In 2004, after resuming communication with authorities, Rader inquired if police could trace information sent on a floppy disk . When police falsely assured him it couldn’t be traced, he sent them a disk that investigators quickly traced back to his church, where he served as congregation president .
The digital evidence from the floppy disk was still circumstantial, but it gave investigators enough to obtain a DNA sample from Rader’s daughter, Kerri, through her medical records from her college health center without her knowledge . This sample provided a familial match to DNA taken from BTK’s crime scenes, confirming Rader’s identity as the BTK killer .
On February 25, 2005, Rader was arrested during his lunch break . He quickly confessed to his crimes, apparently expressing shock that the police had lied to him about tracing the floppy disk . In June 2005, he pleaded guilty to 10 counts of first-degree murder and was sentenced to 10 consecutive life sentences—a minimum of 175 years behind bars—at the El Dorado Correctional Facility, where he remains incarcerated today .
A Daughter’s Nightmare: Kerri Rawson’s Story
For Kerri Rawson, the day of her father’s arrest marked the complete destruction of her reality. She was 26 years old, recently married, and expecting her first child when an FBI agent knocked on her door and delivered the life-shattering news: “your dad is BTK” . Her immediate reaction was disbelief, thinking, “my father’s a good guy. He’s a Boy Scout leader, president of the church” .
The revelation forced Kerri to reevaluate her entire childhood. She recalled a seemingly normal upbringing where her father built her a treehouse, taught her to fish, and attended church with the family . However, darker memories also surfaced—she remembered “moments of dad” when something would trigger him and he would “flip on a dime” . She also suffered from night terrors, bed-wetting, and an intense fear of the dark as a child, wondering in hindsight if her subconscious was warning her about the “bad man in the house” .
Perhaps most chillingly, Rawson discovered that the family station wagon her father gave her to drive in high school was the same vehicle he had used to transport the body of his final victim, Dolores Davis, in the trunk . “Thinking that Mrs. Davis had been in that vehicle,” Rawson recalled with visible anguish. “I was like no that’s not ok” .
Unanswered Questions: Could There Be More Victims?
Even after Rader’s conviction, questions remain about whether BTK Killer committed additional murders beyond the ten confirmed cases. In recent years, authorities have investigated potential connections between Rader and several cold cases:
- Cynthia Dawn Kinney: This 16-year-old disappeared from an Osage County laundromat in 1976, across the street from a bank that had an ADT security system installed . Investigators discovered that a crossword puzzle Rader sent to authorities in 2004 contained not only the names of his known victims but also clues pointing to Kinney, including her name and the words “laundry mat” .
- Shawna Beth Garber: A 22-year-old whose body was found in Missouri in 1990 . Investigators have examined potential links to Rader as well .
In 2023, Kerri Rawson visited her father in prison for the first time in 18 years, confronting him about these unsolved cases. She described the encounter as the “first time he ever dropped his mask and became BTK in front of me” . While Rader has denied killing Kinney, investigations continue, with Rawson assisting law enforcement in their efforts to potentially link him to additional victims .
The Legacy of Trauma: A Family and Community Shattered
The impact of Rader’s crimes extended far beyond his immediate victims, creating lasting trauma throughout the Wichita community. During his reign of terror, BTK transformed Wichita from a “sleepy little friendly town” into a place where people obsessively locked their doors, checked their phone lines, and lived in constant fear . One resident recalled how “BTK was the boogie man made real,” explaining that people were “scared to death to see if he was going to kill again” .
For Kerri Rawson, the aftermath has been a lifelong journey of healing and reconciliation. She has written a memoir, “A Serial Killer’s Daughter: My Story of Faith, Love, and Overcoming,” and continues to speak out about her experience . Despite the trauma, she has worked to reclaim her identity, stating, “I’m a mom… I’m a normal person. And most days I don’t even really think about who my dad is. I’m just me“
This story isn’t just about a killer — it’s about a daughter who refused to let his shadow define her.
