Dennis Rader

• 1. Introduction

  ›

  Dennis Rader, the man who called himself BTK, made a strange request while police questioned him in February 2005. He asked an officer to write "BTK" on the lid of his cup before it went into the refrigerator, instead of his own name.

  The request says a great deal. Rader had built a private identity out of three letters, and he did not want to let it go.

  Between 1974 and 1991, he killed at least ten people in and around Wichita, Kansas. He also wrote to the press and the police. Then the letters stopped, and the case slowly turned cold.

  Through all of it, he was a husband and a father. His neighbors saw a polite man. How does someone keep two lives so completely apart? Why did he need an audience? What made a man who had gone silent decide to return? And what small, almost accidental detail finally led investigators to him?

• 2. The Making Of A Neighbor

  ›

  Dennis Lynn Rader was born in Pittsburg, Kansas, on the 9th of March 1945, the oldest of four sons. His mother, Dorothea, worked as a bookkeeper. His father, William, was a former United States Marine who worked for Kansas Gas Service. Both parents put in long hours, and Rader later said he felt neglected at home. His father was described as strict and devout, though not abusive. The family belonged to Zion Lutheran Church in Pittsburg, where Rader was baptized.

  In Wichita, the boy liked novels, comic books, fishing and cub scouting. Yet from a young age he also nursed violent fantasies about helpless women. He tortured and killed small animals, and he spied on female neighbors while dressed in women's clothing.

  At Wichita Heights High School, he spent his spare hours bagging groceries and stocking shelves at a local store, saving for a vehicle. He graduated in 1963 and enrolled at Kansas Wesleyan University. His grades were mediocre, and he left after a single year.

  In June 1966, Rader joined the United States Air Force. After basic training and technical school in Texas, he went to Brookley Air Force Base in Mobile, Alabama, as an antenna installer. Assignments followed in Turkey, Greece and South Korea. In January 1968 he reached Japan, where he spent six months at Kadena Air Base on Okinawa and twenty-five months at Tachikawa Airfield in Tokyo. He earned a good conduct medal and a marksmanship ribbon. He also received a National Defense Service Medal, because his service fell during the state of emergency tied to the Vietnam War. He left the Air Force with an honorable discharge as a staff sergeant on the 12th of August 1970 and stayed in the reserve until the 20th of June 1972.

  Civilian life then followed a steady track. On the 22nd of May 1971, Rader had married Paula Dietz, a secretary for the American Legion, at Christ Lutheran Church. They had two children, Kerri and Brian. A year after his discharge, he bought a home in Park City, a suburb of Wichita. He earned an associate degree in electronics engineering at Butler County Community College in 1973. In 1979 he finished a bachelor's degree at Wichita State University, majoring in administration of justice.

  His jobs were ordinary. He started in the meat department of an IGA supermarket, where his mother kept the books. From mid-1972 to mid-1973, he assembled products for the Coleman Company, an outdoor equipment maker. Two of his future victims, Julie Otero and Kathryn Bright, worked there as well. From 1974 to 1988, he installed security alarms for the Wichita office of ADT Security Services. Many of his customers were homeowners frightened by the very killings he had committed. Coworkers nicknamed him "blue book man," because he scolded anyone who ignored office rules.

  Neither his wife nor his children suspected a thing. The family's house in Park City was demolished in March 2007.

  ›

  On the 15th of January 1974, the three older Otero children came home from school and found that four members of their family had been killed. Joseph Otero Sr. was 38. His wife, Julia, was 33. Their son Joseph II was 9, and their daughter Josephine was 11. After his arrest, Rader said he first noticed the family two months earlier, when Julia left to take the children to school. He then watched them for two or three weeks.

  On the morning of the attack, he walked from his parked car to the house, climbed a fence and cut the phone lines in the backyard. When the family dog was let out, Rader confronted the boy at the back door and pushed his way in at gunpoint. The Oteros first took it for a prank. Rader told them he was wanted in California and tied them with rope he had prepared in advance. He killed all four.

  His next target was Kathryn Bright, 21, whom he code-named "Project Lights Out." He had not counted on her brother Kevin, 19, who was staying over. Rader said he tried to avoid men, since they made the killings harder. On the 4th of April 1974, he broke in through a sliding glass door and waited. The delicate trigger on his pistol fired by accident, and he worried the smell of gunpowder would give him away.

  When the siblings arrived, Rader said he was a wanted man who needed money and a car. He made Kevin tie up his sister. He used household items such as bandanas as restraints, so the crime would look different from the Otero case. He also turned on a stereo to cover the noise, a trick he said he learned from detective magazines.

  Kevin freed himself. In the struggle that followed, Rader shot him in the forehead and fired twice more. Kevin played dead until Rader left the room, then ran from the house and flagged down neighbors. Kathryn fought back as well, and Rader stabbed her. She was still alive when police arrived but died in emergency surgery. Kevin was told several days later, in the hospital.

  Three years passed before the next attack. On the 17th of March 1977, Rader had a different victim in mind, but she was not home. Frustrated, he went looking for anyone else. He met Steven Relford, aged 5, who was walking home with soup for his sick mother. Rader posed as a detective and showed the boy a photograph. Then he followed Steven to the home of Shirley Vian Relford. He locked her three children in a bathroom, told her it was a robbery and killed her. He later admitted he planned to kill the children too. Then the phone rang, one of the children shouted that a visitor was due soon, and Rader fled.

  Nancy Jo Fox, 25, had been stalked for some time and was code-named "Project Foxhunt." On the 8th of December 1977, Rader entered through a back window and waited for her to come home from work. She screamed at him to leave and threatened to call police. He had already cut her phone lines. When she questioned the handcuffs, he answered, "That's part of my deal. I got to have them or it won't work." He killed her with his belt.

  In April 1979, Rader broke into the home of Anna Williams, 63, intending to kill her. She came back from visiting friends much later than expected, and he gave up and left. He later told investigators he had been "absolutely livid."

• 4. Letters And Poems

  ›

  In October 1974, a letter reached The Wichita Eagle, signed with the initials BTK. They stood for "bind, torture, kill." The writer took credit for the Otero killings and supplied details that had not been made public. "I did it by myself and no ones help," he wrote. The line was aimed at three brothers in psychiatric care who had falsely confessed to the crime the month before. A man in Washington, D.C. had also been arrested that July, then cleared by a fingerprint comparison. The Wichita Beacon answered with a classified ad in several late October issues: "B.T.K Help is Available. Call 684-6321 before 10 p.m."

  The day after Nancy Fox died, on the 9th of December 1977, Rader phoned police from a phone booth and told them where to find her body. The call was recorded. When it was played to the public in 1979, it brought in more than a hundred tips, none of them promising.

  On the 31st of January 1978, he mailed the Beacon's classified department a poem that opened with the words "Shirleylocks, shirleylocks." It went on to describe the Relford killing in detail. Because it was addressed to the Beacon rather than the classified desk, it took weeks to arrive.

  His boldest message followed on the 10th of February 1978, sent to the television station KAKE. He claimed the Otero, Bright, Relford and Fox killings and complained that he was being ignored. "How many do I have to kill, before I get a name in the paper or some national attention?" he asked. He offered several possible names for himself, BTK among them. He blamed a force he called "factor X," which he said also drove Jack the Ripper, the Son of Sam and the Hillside Stranglers. He told police to answer with a hidden message. Investigators traced the letter to a copy machine at the Wichita State University library, where Rader was then a student. A poem titled "Oh! Death to Nancy," a parody of the folk song "O Death," was enclosed.

  On the 15th of June 1979, Rader left an envelope outside Anna Williams's home. It read "Oh Anna, Why Didn't You Appear?" and carried his BTK signature. Inside were a drawing of a bound woman, a scarf and two plastic clips, all taken during the April break-in. Detectives had privately wondered whether that break-in was linked to BTK, and now they knew.

  The last of these messages came in January 1988. Mary Fager received an envelope postmarked the 5th of January, holding a poem and a picture of a bound girl. Her husband, Melvin, and their daughters Sherri, 10, and Kelli, 16, had been killed in their home on the 27th of December 1987. Rader has never been tied to those murders and does not claim them. He said only that he admired the crime. The drawing he made of the scene did not match what had really happened.

• 5. The Quiet Years

  ›

  On the night of the 27th of April 1985, Rader slipped away from a Cub Scouts outing by faking a headache. He had picked a target who lived only a few houses from his own home. Marine Hedge, 53, was code-named "Project Cookie." He wanted to test whether he could kill a neighbor and get away with it. Rader changed out of his scout clothes and went to a bowling alley, where he splashed beer on himself. Then he phoned a taxi in a slurred, drunken voice and was dropped a street from where he and Hedge lived.

  He cut her phone line, hid in a bedroom closet and waited for her to come home with her boyfriend. After the boyfriend left, he attacked and killed her. He then drove her body to Christ Lutheran Church, where he had keys, and photographed it with the windows covered. Before dawn he cleaned up and left her in a remote ditch. Police found her abandoned car on the 2nd of May. Her body was recovered on the 5th of May, 7 miles from her home.

  On the 16th of September 1986, Rader used his ADT hard hat and a telephone company manual to pass himself off as a technician. He visited a neighbor first to look believable, then knocked on the door of Vicki Wegerle, 28, whom he called "Project Piano." She fought him and scratched his face hard enough that, twenty years later, he said he might still have the mark. Rader killed her anyway. Witnesses saw her car leave at 10:30 that morning, and police found it at 12:10. For almost two decades, some people believed her husband, Bill, was the killer, and he lived under a cloud of suspicion.

  On the 18th of January 1991, the Trappers Scouts held their annual "dead of winter" outing at Harvey County Park West. Rader set up camp, invented a story and left. He used a key to Park City Baptist Church, which he held through his scouting duties, and walked to the home of Dolores Davis, 62. He called her "Project Dogside" after the dog kennels near her house. He killed her, then moved her body twice. He threw her keys on the roof because he had read that police searched the Oteros' roof for keys. Fifteen-year-old Nelson Schock found her body on the 1st of February 1991 after following his dog under a bridge.

  Police did not link Hedge or Davis to BTK at first. Between killings, Rader committed many burglaries, mostly taking underwear, jewelry and money. He took keepsakes from his female victims, including underwear and driver's licenses. Yet he was widely regarded as normal, polite and well mannered. He led Cub Scouts and belonged to Christ Lutheran Church.

  In 1989, he supervised field operations in the Wichita area for the 1990 census. In May 1991, he became the dogcatcher and compliance officer for Park City. Neighbors called him overzealous. One saw him on their lawn with a tape measure, checking whether the grass was too long. Another woman said he killed her dog for no reason. From 1996 to 1998 he sat on the Sedgwick County Animal Control Advisory Board.

  Some neighbors remembered him enjoying the harassment of single women. Two women he stalked in the 1980s, and one in the mid-1990s, obtained restraining orders against him. One of them moved to escape him.

• 6. The Long Hunt

  ›

  In 1978, detectives who knew BTK watched KAKE's newscasts tried a trick. During one evening broadcast, the station flashed a message for a split second: "Now call the chief." Beside it was a drawing of an upside-down pair of glasses, matching a pair found at the Fox scene. Police hoped the suspect would give himself up. He did not.

  In the mid-1980s, a new task force took over. Its members were nicknamed the "Ghostbusters." Advances in forensic science gave them new tools. Over three years, they compared blood and saliva samples from as many as 225 suspects, many of whom no longer lived in Wichita. All but seven were cleared.

  By the 1990s, the case was still open, but detectives described their frustration with thin leads and useless tips. Many former investigators on the case came to believe BTK was in prison, in an institution or dead. Others thought he might have found a submissive partner who let him act out his fantasies. At a Wichita State University lecture, the former FBI agent Robert Ressler guessed that the killer was a graduate student in criminal justice. He was right. In 1998, investigators turned to geographic profiling to estimate where BTK might live.

  By the early 2000s, the file was a cold case. Local author Robert Beattie started a book, Nightmare in Wichita, after learning that many young people had never heard of the murders. In January 2004, ahead of the thirtieth anniversary of the Otero killings, the Eagle ran a story headlined "BTK case unsolved, 30 years later." In a 2005 interview, Rader said he read it and felt "kind of bored," which pushed him to start writing again.

• 7. The Return

  ›

  On the 19th of March 2004, the Eagle received a letter signed "Bill Thomas Killman," claiming the 1986 killing of Vicki Wegerle. Enclosed were photographs of the crime scene and a photocopy of her driver's license, taken at the time. Until then, police had not firmly connected her death to BTK. DNA taken from under her fingernails gave them a new lead. They began testing hundreds of men, including police officers and college professors. More than 1,300 DNA samples were collected, and a court later ordered them destroyed.

  More messages followed. In May, KAKE received chapter headings for a proposed book called The BTK Story, along with fake IDs and a word puzzle. On the 9th of June, a package taped to a stop sign at First and Kansas roads in Wichita held graphic descriptions of the Otero killings and a sketch labeled "The Sexual Thrill Is My Bill." The chapter list echoed a 1999 BTK story by Court TV writer David Lohr. In July, a package left in a library return slot claimed BTK had caused the death of Jake Allen, 19, in Argonia, Kansas. That was false. His death was ruled a suicide.

  Rader's letters gave away real facts, such as that he had served in the military and loved trains. He also lied, claiming he was born in 1939 and moved often as a child. After his capture, he admitted he had set a date in October 2004 to kill again and was already stalking someone. That month, an envelope dropped into a UPS box in Wichita held cards with images of terror and bondage, a poem threatening the lead detective, Lieutenant Ken Landwehr, and a false autobiography. In December, police found a package in Murdock Park containing Nancy Fox's stolen driver's license and a doll bound at the hands and feet, with a plastic bag over its head.

  In January 2005, Rader tried to leave a cereal box in the bed of a pickup truck at a Home Depot in Wichita. The owner threw it away. Rader later asked about it, and police pulled it from the trash. Parking lot video showed a distant figure in a black Jeep Cherokee leaving it. A second box with another bound doll turned up at a rural spot in February.

  Rader also asked, in his letters, whether his writing on a floppy disk could be traced. Police answered through a classified ad in the Eagle: "Rex, it will be ok." On the 16th of February, he mailed a purple 1.44-megabyte Memorex floppy disk to the Wichita station KSAS-TV. With it came a letter, a gold-colored necklace with a large medallion and a copy of the cover of Rules of Prey, a 1989 novel by John Sandford about a serial killer.

  Unknown to Rader, the disk still held a deleted Microsoft Word file. Its metadata contained the words "Christ Lutheran Church," and the file was last modified by "Dennis." An Internet search showed that a Dennis Rader was president of the church council, a post he had won that January. Detectives drove past his home and saw a black Jeep Cherokee outside. It was strong circumstantial evidence, but not enough to arrest him.

  Police then obtained a warrant to test a pap smear taken from Rader's daughter at the Kansas State University medical clinic. The DNA showed a familial match to the sample from Wegerle's fingernails. The killer was a close relative of Rader's daughter.

  Rader was arrested near his Park City home shortly after noon on the 25th of February 2005. An officer asked, "Mr. Rader, do you know why you're going downtown?" He replied, "Oh, I have suspicions why." Investigators from the Wichita Police Department, the Kansas Bureau of Investigation, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives searched his home and vehicle. They seized computer equipment, a pair of black pantyhose from a shed and a cylindrical container. They also searched the church, his office and the main Park City library.

  In questioning, Rader kept asking about the death penalty in Kansas and what sentence he would receive. He wanted to know if he would be held in a "special section" of prison or among the "loonies." At a press conference the next morning, Wichita Police Chief Norman Williams announced, "The bottom line: BTK is arrested."

• 8. Courtroom And Aftermath

  ›

  On the 28th of February 2005, Rader was charged in Sedgwick County District Court with ten counts of first-degree murder. Bail was set at US$10 million, and a public defender was appointed. On the 3rd of May, the judge entered not guilty pleas for him because he said nothing at his arraignment. On the 27th of June, the day his trial was due to begin, he pleaded guilty. He described each killing to the court in a flat tone and offered no apology.

  At his sentencing on the 18th of August, the victims' families spoke first. Rader then apologized in a rambling thirty-minute monologue, which the prosecutor compared to an Academy Awards acceptance speech. He received ten consecutive life sentences, with a minimum of 175 years. Kansas was not enforcing the death penalty when the murders took place. The next day he was taken to the El Dorado Correctional Facility. During the forty-minute drive he chatted about the weather, but he wept when the radio played the families' statements. On the 26th of July, his wife had been granted an emergency divorce, which waived the usual sixty-day wait.

  Before the plea, his defense lawyers had hired the Massachusetts psychologist Robert Mendoza to judge whether an insanity defense could work. Mendoza diagnosed narcissistic, obsessive-compulsive and antisocial personality disorders. He described a grandiose man who thought himself special, craved admiration, demanded rigid order and felt no empathy. The videotape of the interview later aired on Dateline NBC. On the 25th of October 2005, Kansas Attorney General Phill Kline filed suit against Mendoza and his business partner Tali Waters, accusing them of seeking to profit from the case. Mendoza settled on the 10th of May 2007 for US$30,000, admitting no wrongdoing.

  Rader now lives in solitary confinement for his own protection. In April 2006, prison officials cited his good behavior in granting him a television, a radio, books and art supplies. Prosecutors had argued against it, fearing the images and news accounts would let him relive his fantasies. His daughter Kerri Rawson published A Serial Killer's Daughter in 2019. She said she writes to her father and has forgiven him, yet still struggles to square her ordinary childhood with who raised her. After visiting him in 2023, she described him as unhappy, much thinner and in a wheelchair. At Crime Con in 2024, she shared excerpts from his journal that suggested he had sexually abused her as a child. She also said prison officials had disciplined him for sending clothing, glasses and BTK-themed art to fans.

  The case has inspired many works. Katherine Ramsland wrote Confession of a Serial Killer from five years of correspondence with him. Stephen King has said his novella A Good Marriage was inspired by BTK. Thomas Harris has said the character Francis Dolarhyde in Red Dragon was partly based on the then-unidentified killer. Netflix released the documentary My Father, the BTK Killer in 2025, directed by Skye Borgman, centered on Rawson and the family's ordeal.

  After the arrest, police in Wichita and nearby towns reviewed unsolved cases, especially those after 1994, when Kansas restored the death penalty. They found no further murders they could definitively attribute to him. Wichita police believe he stalked other potential victims. One was spared when he called off an attack because construction crews were nearby. "There are a lot of lucky people," Rader told police.

  In August 2023, the Associated Press reported that a new search of evidence from his home turned up "possible trophies." One lead concerns Cynthia Dawn Kinney, 16, who vanished from a laundromat in Osage, Oklahoma, on the 23rd of June 1976. Sheriff Eddie Virden said Rader attended Cub Scout events in the area and used the phrase "bad wash day" in his writings. Rader denies involvement, and Virden thinks he fears an Oklahoma trial and a possible death sentence. Kinney's case remains unresolved.
