Dennis Lynn Rader (born March 9, 1945), also known as BTK (an abbreviation he gave himself for "bind, torture, kill"), is an American serial killer who murdered at least ten people in Wichita and Park City, Kansas, between 1974 and 1991. Although he occasionally killed or attempted to kill men and children, Rader typically targeted women. His victims were often bound, sometimes with objects from their homes, and either suffocated with a plastic bag or manually strangled with a ligature. In addition, he stole keepsakes from his female victims, including underwear, driver's licenses, and personal items.

Rader often sent taunting letters to police and media outlets, describing his crimes in detail. In 2004, after a thirteen-year hiatus, Rader resumed sending letters, leading to his 2005 arrest and subsequent guilty plea. He is currently serving ten consecutive life sentences at the El Dorado Correctional Facility.

Life and background

Dennis Lynn Rader was born in Pittsburg, Kansas, on March 9, 1945. His parents were bookkeeper Dorothea Mae Rader (née Cook; September 17, 1925 – October 14, 2007) and Kansas Gas Service worker William Elvin Rader (November 21, 1922 – December 27, 1996). He was the eldest of four sons. Growing up in Wichita, Rader later recalled feeling ignored by his mother. Both of his parents worked long hours and paid little attention to their children at home.

From a young age, Rader harbored sadistic sexual fantasies about torturing "trapped and helpless" women. He also exhibited zoosadism by torturing, killing and hanging small animals. Rader acted out sexual fetishes for voyeurism, autoerotic asphyxiation and cross-dressing, often spying on female neighbors while dressed in women's clothing, including women's underwear that he had stolen. He also masturbated with ropes or other bindings around his arms and neck.

Years later, during his "cooling off" periods between murders, Rader would take pictures of himself wearing women's clothes and a female mask while bound. He later admitted that he was pretending to be his victims as part of his sexual fantasy. However, Rader kept his proclivities well hidden, and was widely regarded in his community as "normal, polite, and well mannered."

After graduating from Wichita Heights High School, Rader attended Kansas Wesleyan University. He received only mediocre grades and dropped out after one year. Rader served in the United States Air Force from 1966 to 1970. On discharge, he moved to Park City, a suburb of Wichita, where he worked in the meat department of an IGA supermarket where his mother was employed as a bookkeeper.

Rader married Paula Dietz on May 22, 1971. They had two children, Kerri and Brian. He attended Butler County Community College in El Dorado, earning an associate degree in electronics engineering in 1973. He then enrolled at Wichita State University and graduated in 1979 with a Bachelor of Science degree, majoring in administration of justice.

Rader initially worked as an assembler for the Coleman Company, an outdoor supply company. He then worked at the local Wichita office of ADT Security Services from 1974 to 1988, where he installed security alarms. Ironically, many of his clients were concerned homeowners seeking security from his own killings as BTK. Rader was a field operations supervisor for the Wichita area for the 1990 federal census.

In May 1991, Rader became a dogcatcher and compliance officer in Park City. In this position, neighbors recalled him as being sometimes overzealous and extremely strict, as well as taking special pleasure in bullying and harassing single women. Two women he stalked in the 1980s, and one whom he stalked in the mid-1990s, filed restraining orders against him; one of these women also changed her address to avoid him. One neighbor complained that Rader killed her dog for no reason. Rader was a member of Christ Lutheran Church in Wichita, and at one point was elected president of the church council. He was also a Cub Scout leader and would frequently use being with the scouts as his alibi when a BTK killing was discovered.

By the 2000s, the public's memories of the murders had begun to fade. Local author Robert Beattie began writing a book about the killings, Nightmare in Wichita, after being shocked that many young people he spoke to had never heard of the BTK case. Hungry for attention, Rader re-emerged as BTK in 2004 after learning that the book was being written.

On July 26, 2005, after Rader's arrest, his wife was granted an emergency divorce, waiving the normal sixty-day waiting period. In an interview with ABC News in 2019, his daughter Kerri stated she writes to her father and has now forgiven him, but still struggles to reconcile her "normal" childhood with the knowledge that she was raised by the BTK killer. However, at the 2024 Crime Con in Nashville, Tennessee, Kerri revealed excerpts from her father's journal that revealed he had sexually abused her as a young girl.

Case history

Confirmed murders

Otero Murders

On January 15, 1974, four members of the Otero family were murdered in Wichita. The victims were Joseph Otero Sr. (38), Julia Maria "Julie" Otero (33), Joseph "Joey" Otero II (9) and Josephine "Josie" Otero (11). Their bodies were discovered by the family's three older children, who had been at school at the time of the killings. After his 2005 arrest, Rader confessed to the Otero murders. He claimed that he first targeted the family two months prior, when he spotted Julie leaving to take her children to school and followed them. On the morning of January 15, Rader cut the phone lines and entered the Otero residence when Joey opened the back door for the family dog.

Rader told the Otero family that he was a "wanted" man in California before he ordered them to lie on the living room floor at gunpoint. Then, he led the family into a bedroom and bound them with rope he had prepared. Joseph and Joey were on the floor, while Julie and Josie were on the bed. The wrists and feet of Joseph and Julie were restrained. Joseph's head was covered by a plastic bag, which Rader then secured with ropes. After Joseph chewed a hole in the bag, another bag was tightened over his head, causing him to slowly suffocate to death.

Rader attempted to strangle Julie, later recalling: "Mrs. Otero woke back up. She was pretty upset with what was going on, and she asked me to save her son, so I took the bag off. She screamed, 'You killed my boy! You killed my boy!' After the initial realization and shock, she communicated, 'God have mercy on your soul,' before I put her down, permanently." Rader strangled Julie to death with rope. With both parents dead, Rader then placed another plastic bag, followed by two T-shirts and an additional bag, over Joey's head, watching as he thrashed and suffocated. Afterward, Rader led Josie down into the basement, where he hanged her with a noose from a pipe. Later, police found Rader's semen near Josie's partially clothed body. Rader eventually wrote a letter that he stashed inside an engineering book in the Wichita Public Library in October 1974, describing the Otero killings in detail.

Murder of Kathryn Bright

On April 4, 1974, Rader broke into the Wichita home of Kathryn Doreen Bright (21) through her screen door but was taken aback to discover her 19-year-old brother, Kevin Bright, was also present in the property. He transported Kathryn to another bedroom and tied her down after forcing Kevin, who was being held at gunpoint, to restrain his sister with a rope Rader had provided. Rader attempted to strangle Kathryn before stabbing her three times in the back and lower abdomen with a knife when she struggled too much. Kevin was also strangled and shot in the head, but he survived by feigning death and later escaping.

Murder of Shirley Ruth Relford

On March 17, 1977, Shirley Ruth Relford (25) was found dead in her home in Wichita. Rader was pursuing Relford and located her by following her 5-year-old son to her home. Rader entered their residence and produced a handgun from his jacket, frightening the family. After tying up her three children and locking them in the bathroom, Rader took Relford to the rear bedroom. Relford vomited before being tied to her bedpost by her legs. Rader strangled her with rope after placing a plastic bag over her head, while her children screamed and banged down the hallway. Similar to the Otero murders, Rader intended to murder Relford's children, although they were ultimately able to escape before he could do so.

Murder of Nancy Jo Fox

When Rader noticed Nancy Jo Fox (25) going into her home in Wichita, he marked her as a potential victim and began stalking her. On December 8, 1977, Rader knocked at her door. When nobody answered, he cut the phone lines before breaking in to wait for Fox in her kitchen. Her murder would be described by Rader as "what I call a perfect – perfect hit. Although she gave me a lot of verbal static, she cooperated, and she didn't fight me. I had complete control of her, that's why it was one of the more enjoyable kills, as I call them." Rader killed Fox by strangling her with his belt on her bed. Before she died, Rader told her that he was responsible for the Otero murders. The following day, Rader called police from a payphone, telling them they would find Fox's body at her home.

BTK asks for infamy

On February 10, 1978, Rader sent another letter to Wichita television station KAKE claiming responsibility for the murders. He suggested many possible names for himself, including "BTK." He demanded media attention in this second letter, saying, "How many do I have to kill, before I get a name in the paper or some national attention?" A poem was enclosed titled "Oh! Death to Nancy," a parody of the lyrics to the American folk song "O Death". In the letter, Rader claimed to be driven to kill by "factor X," which he characterized as a supernatural element that also motivated Jack the Ripper, the Son of Sam and the Hillside Stranglers. He also asked for the police to send him a hidden message. In response, and with the knowledge that the BTK killer watched KAKE, police decided to flash a subliminal message during one of the station's evening newscasts for a split second. The message stated: "Now call the chief," and featured a drawing of an upside-down pair of glasses, which were found at the Fox crime scene. They hoped the message would influence the killer to turn himself in, but it was unsuccessful.

Attempted Murder of Anna Williams

During this time, Rader also intended to kill others, such as Anna Williams (63), who, in 1979, escaped death by returning home much later than expected. Rader explained during his confession that he became obsessed with Williams and was "absolutely livid" when she evaded him. He recalled spending hours waiting at Williams' home but becoming impatient and leaving when she did not return from visiting friends.

Murder of Marine Hedge

Marine Hedge (53) was found on May 5, 1985, at East 53rd Street North in Wichita, between North Webb Road and North Greenwich Road. Rader had killed her on April 27 and took her body to Christ Lutheran Church, where he was the president of the church council. There, he photographed her body in various suggestive positions. Rader had previously stored black plastic sheets and other materials at the church in preparation for the murder and then, later, dumped the body in a remote ditch.

Murder of Vicki Wegerle

On September 16, 1986, Rader strangled Vicki Lynn Wegerle (28) to death with a nylon stocking at her house in Wichita. He entered the residence by pretending to be a telephone repairman. After the murder, he rearranged her clothes and took a number of photographs of her nude body.

Murder of Dolores Davis

His final victim, Dolores Earline "Dee" Davis (62), was found dead on February 1, 1991, at West 117th Street North and North Meridian Street in Park City. Rader had killed her on January 19 by strangling her with pantyhose.

Suspected murders

On August 23, 2023, the Associated Press reported that Rader was considered the prime suspect in two further killings in Oklahoma and Missouri. Authorities discovered "possible trophies" from victims after launching a search for evidence at Rader's former Park City home, resulting in the investigation of his potential involvement in additional unsolved disappearances and murders:

Cynthia Dawn Kinney (16) was last seen in Osage, Oklahoma, on June 23, 1976, at Osage Laundromat. Witnesses said she left the laundromat at 9:30 a.m. and got into a faded beige 1965 Plymouth Belvedere. In 2023, Osage Sheriff Eddie Virden claimed that Rader had been identified as a prime suspect after it was determined that he was involved in Boy Scout events in the area and when it was learned that Rader had included the phrase "bad wash day" in his writings. A bank was also having new ADT alarms installed, across the street from the laundromat, when Kinney went missing; Rader was a regional installer for ADT at the time. Furthermore, Rader has allegedly claimed to have "fantasized about kidnapping a girl from a laundromat." Rader has denied involvement in the murder, which Virden believes is due to possibly being tried in Oklahoma and potentially being given the death penalty.

Cold case

By 2004, the investigation of the BTK killer was considered a cold case. However, Rader initiated a series of 11 communications to local media, which led directly to his arrest in February 2005. In March 2004, The Wichita Eagle received a letter from someone using the name "Bill Thomas Killman" claiming that he had murdered Vicki Wegerle in 1986. Enclosed with the message were photographs of the crime scene and a photocopy of Wegerle's driver's license, which had been stolen at the time of the crime. Prior to this message, it had not been definitively established that Wegerle was killed by BTK. DNA collected from under her fingernails provided police with previously unknown evidence. They began DNA testing hundreds of men in an effort to find the killer. Altogether, more than 1,300 DNA samples were taken and later destroyed by court order.

In May 2004, KAKE received a letter with chapter headings for the "BTK Story", fake IDs and a word puzzle. On June 9, a package was found taped to a stop sign at the corner of First and Kansas roads in Wichita, which contained graphic descriptions of the Otero murders and a sketch labeled "The Sexual Thrill Is My Bill." Also enclosed was a chapter list for a proposed book titled The BTK Story, which mimicked a story written in 1999 by Court TV crime writer David Lohr. Chapter One was titled "A Serial Killer Is Born." In July, a package dropped into the return slot at a public library contained more bizarre material, including the claim that BTK was responsible for the death of 19-year-old Jake Allen in Argonia, Kansas, earlier that month. This claim was false, and that death was ruled a suicide.

After his capture, Rader admitted in his interrogation that he had been planning to kill again, that he had set a date (October 2004) and was stalking his intended victim. That month, a manila envelope was dropped into a UPS box in Wichita. It contained many cards with images of terror and bondage of children pasted on them, a poem threatening the life of lead investigator Lieutenant Ken Landwehr and a false autobiography with many details about Rader's life. These details were later released to the public. In December 2004, Wichita police received another package from the killer. This time, the package was found in Wichita's Murdock Park. It contained the driver's license of Nancy Fox, which was noted as stolen from the crime scene, as well as a doll that was symbolically bound at the hands and feet with a plastic bag tied over its head.

In January 2005, Rader attempted to leave a cereal box in the bed of a pickup truck at a Home Depot in Wichita, but the box was discarded by the truck's owner. It was later retrieved from the trash after Rader asked what had become of it in a later message. Surveillance tape of the parking lot from that date revealed a distant figure driving a black Jeep Cherokee leaving the box in the pickup. In February 2005, more postcards were sent to KAKE, and another cereal box left at a rural location was found to contain another bound doll.

In his letters to police, Rader asked if his writings, if put on a floppy disk, could be traced or not. The police answered his question in a newspaper ad posted in the Eagle, saying it would be safe to use the disk. On February 16, 2005, Rader sent a purple 1.44-Megabyte Memorex floppy disk to Wichita station KSAS-TV. Also enclosed were a letter, a gold-colored necklace with a large medallion and a photocopy of the cover of Rules of Prey, a 1989 novel by John Sandford about a serial killer. Police found metadata embedded in a deleted Microsoft Word document that was, unknown to Rader, still stored on the floppy disk. The metadata contained the words "Christ Lutheran Church" and the document was marked as last modified by "Dennis." An Internet search determined that a "Dennis Rader" was president of the church council. When investigators drove by Rader's house, a black Jeep Cherokee—the type of vehicle seen in the Home Depot surveillance footage—was parked outside. This was strong circumstantial evidence against Rader, but they needed more direct evidence to detain him.

Police obtained a warrant to test a pap smear taken from Rader's daughter at the Kansas State University medical clinic. DNA tests showed a "familial match" between the pap smear and the sample from Wegerle's fingernails; this indicated that the killer was closely related to Rader's daughter and, combined with the other evidence, was enough for police to arrest Rader.

Arrest

Rader was arrested while driving near his home in Park City shortly after noon on February 25, 2005. An officer asked, "Mr. Rader, do you know why you're going downtown?" Rader replied, "Oh, I have suspicions why." Wichita Police, the Kansas Bureau of Investigation, the FBI and ATF agents searched Rader's home and vehicle, seizing evidence including computer equipment, a pair of black pantyhose retrieved from a shed and a cylindrical container. Christ Lutheran Church, Rader's office and the main branch of the Park City library were also searched. At a press conference the next morning, Wichita Police Chief Norman Williams announced, "The bottom line: BTK is arrested."

Legal proceedings

On February 28, 2005, Rader was charged with 10 counts of first degree murder. Soon afterward, the Associated Press cited an anonymous source alleging that Rader had confessed to other murders in addition to those with which he had been connected. However, the Sedgwick County district attorney denied the story, yet refused to say whether Rader had made any confessions or if investigators were looking into his possible involvement in more unsolved killings. On March 5, news sources claimed to have verified by multiple sources that Rader had confessed to the 10 murders he was charged with, but no other ones.

On March 1, Rader's bail was set at US$10 million, and a public defender was appointed to represent him. On May 3, the judge entered not guilty pleas on Rader's behalf, as Rader did not speak at his arraignment; however, on June 27, the scheduled trial date, Rader changed his plea to guilty. He described the murders in detail to the court and made no apologies.

At Rader's August 18 sentencing, victims' families made statements, after which Rader apologized in a rambling 30-minute monologue that the prosecutor likened to an Academy Awards acceptance speech. His statement has been described as an example of an often-observed phenomenon among psychopaths: their inability to understand the emotional content of language. Rader was sentenced to 10 consecutive life sentences, with a minimum of 175 years. Kansas did not enforce the death penalty at the time of the murders. On August 19, Rader was moved to the El Dorado Correctional Facility.

Rader talked about innocuous topics such as the weather during the forty-minute drive to El Dorado but began to cry when the victims' families' statements from the court proceedings came on the radio. He is now in solitary confinement for his protection (with one hour of exercise per day and showers three times per week). This will likely continue indefinitely. Beginning in 2006, Rader was allowed access to television and radio, to read magazines and other privileges for good behavior.

Further investigations

Following Rader's arrest, police in Wichita and several surrounding cities looked into unsolved cases with the cooperation of the state police and the FBI. They particularly focused on cases after 1994, when the death penalty was reinstated in Kansas. Police in surrounding states also investigated cold cases that fit Rader's pattern. After exhaustive investigations, none of these agencies discovered any further murders attributable to Rader, supporting early suspicions that he would have taken responsibility for any additional murders that he had committed. As a result, the ten known murders were at that point believed to be the only murders for which Rader was actually responsible, although Wichita police are fairly certain that he stalked and researched a number of other potential victims. This includes one person who was saved when Rader called off his planned attack upon his arrival near the target's home due to the presence of construction and road crews nearby. Rader stated in his police interview that "there are a lot of lucky people", meaning that he had thought about and developed various levels of murder plans for other victims.

Evaluation by Robert Mendoza

Massachusetts psychologist Robert Mendoza was hired by Rader's public defenders to conduct a psychological evaluation and determine if an insanity-based defense might be viable. He conducted an interview after Rader had pleaded guilty on June 27, 2005. Mendoza diagnosed Rader with narcissistic, obsessive-compulsive and antisocial personality disorders: he observed that Rader has a grandiose sense of self, a belief that he is "special" and therefore entitled to special treatment; a pathological need for attention and admiration; a preoccupation with maintaining rigid order and structure; and a complete lack of empathy.

The videotape of Mendoza's interview ended up being used on NBC's Dateline. NBC claimed Rader knew the interview might be televised, but this was false according to the Sedgwick County Sheriff's Office. Rader mentioned the interview during his sentencing statement. On October 25, 2005, the Kansas attorney general filed a petition to sue Mendoza and Tali Waters, co-owners of Cambridge Forensic Consultants LLC, for breach of contract, claiming that they intended to benefit financially from the use of information obtained through involvement in Rader's defense. On May 10, 2007, Mendoza settled the case for US$30,000 with no admission of wrongdoing.
