Dennis Rader is an American convicted serial killer better known by the name BTK. He murdered 10 people in and around Wichita, Kansas, between 1974 and 1991 while presenting himself to his family and community as an ordinary husband, father, employee and church leader.
For decades, Rader avoided identification while sending disturbing communications to police and news organizations. His desire for attention eventually contributed to his capture. Investigators traced information on a floppy disk to his church and then used familial DNA evidence to strengthen the case against him.
Rader was arrested on February 25, 2005. He pleaded guilty to 10 counts of first-degree murder and received 10 consecutive life sentences. As of September 2026, he is 81 years old, still alive and imprisoned at El Dorado Correctional Facility in Kansas.
This article explains Rader’s early life, family, known crimes, arrest and current situation. It also separates his 10 confirmed murders from later claims connecting him to unresolved cases.

Early Life and Childhood
Dennis Lynn Rader was born on March 9, 1945, in Pittsburg, Kansas. He grew up in Wichita and was the oldest of four sons born to William Elvin Rader and Dorothea Mae Rader.
Accounts describe an outwardly ordinary Midwestern upbringing involving fishing and scouting. Rader later claimed that his violent fantasies began when he was young, but many childhood details come from his own statements. No single childhood experience can responsibly be presented as the cause of his crimes.
Dennis Rader Education
Rader graduated from Wichita Heights High School in 1963. He briefly attended Kansas Wesleyan University, but he left before completing a degree.
After his military service, he continued his education. He studied at Butler County Community College and later attended Wichita State University. In 1979, he earned a bachelor’s degree in administration of justice.
The degree became a striking part of his story because he studied criminal justice while secretly committing crimes. There is no evidence that the university or his classmates knew about them.
Dennis Rader Nationality, Ethnicity and Religion
Rader is an American citizen and is generally described as a white American. He spent most of his life in Kansas, especially in the Wichita and Park City areas.
Religion was a visible part of his public identity. He was raised in the Lutheran faith and later became active at Christ Lutheran Church. At the time of his arrest, he was serving as president of the church council.
His church involvement strengthened the respectable public image that concealed his criminal life. There is no evidence that the church or its members knew about his actions.
Dennis Rader Age, Height and Physical Appearance
Rader turned 81 years old on March 9, 2026. Public records and news photographs provide a general picture of his appearance, but commonly repeated height and weight figures are not always supported by accessible official records.
| Feature | Information |
|---|---|
| Age | 81 years old in 2026 |
| Hair | Brown when younger; grey or white in later life |
| Eyes | Brown |
| Build | Average build during his working years |
| Current mobility | Reportedly uses a wheelchair, according to his daughter |
| Height | Frequently reported online, but not consistently verified |
Reports about Rader using a wheelchair come largely from Kerri Rawson’s description of prison visits. His complete medical history is private, so claims about specific diseases or a terminal condition should not be presented as fact without confirmation from prison authorities.
Military Service in the United States Air Force
Rader joined the United States Air Force in 1966. He served on active duty until 1970 and reportedly reached the rank of staff sergeant. His service included time outside the continental United States.
After leaving active service, he returned to Kansas. His military background contributed to the disciplined image he presented to employers and neighbors, but no verified evidence connects his service to his crimes.
Dennis Rader Career and Employment History
Rader held several ordinary jobs during the years in which he committed his known crimes. He worked briefly for the Coleman Company and later joined ADT Security Services in 1974.
At ADT, Rader installed and serviced security systems, giving him knowledge of home alarms. This does not prove that every part of his criminal activity was connected to his employment.
He left ADT in the late 1980s. In 1991, he began working for Park City, Kansas, as a compliance officer. The job included enforcing local rules covering property maintenance, animals and other municipal matters. Some residents later remembered him as unusually strict or controlling in that role.
Rader also volunteered as a Cub Scout leader and became active in his Lutheran church. These positions helped create the appearance of a responsible community member.
The Double Life of a Family Man and Church Leader
To his family, Rader appeared to be a working husband and father who attended church and joined community activities. At the same time, he secretly stalked people, committed murders and kept records connected to his crimes. The available evidence does not show that Paula Dietz, Brian Rader or Kerri Rawson knowingly helped conceal them.
Why Was Dennis Rader Called the BTK Killer?
Rader created the name BTK himself. The initials referred to the phrase “bind, torture, kill.” He used the name in communications claiming responsibility for murders and demanding public attention.
The nickname became famous through media coverage, but it was part of Rader’s effort to create a frightening public identity. Responsible coverage should therefore name the victims and avoid making his chosen label more important than their lives.
When Did Dennis Rader Crimes Begin?
Rader’s first confirmed murders occurred on January 15, 1974, when four members of the Otero family were killed in their home in Wichita, Kansas. The victims were Joseph Otero Sr., Julie Otero, Joseph Otero Jr. and Josephine Otero.
He committed another murder in April 1974 and later killed people in 1977, 1985, 1986 and 1991. His last confirmed victim was Dolores Davis, who was killed in January 1991.
Years sometimes passed between confirmed murders. His later descriptions of stalking and planning should be treated carefully because he repeatedly sought attention and control over the public story.
Dennis Rader Confirmed Victims
Rader pleaded guilty to murdering 10 people. The following table keeps the focus on their identities without repeating unnecessary graphic details.
| Victim | Date or year | Location |
|---|---|---|
| Joseph Otero Sr. | January 15, 1974 | Wichita, Kansas |
| Julie Otero | January 15, 1974 | Wichita, Kansas |
| Joseph Otero Jr. | January 15, 1974 | Wichita, Kansas |
| Josephine Otero | January 15, 1974 | Wichita, Kansas |
| Kathryn Bright | April 4, 1974 | Wichita, Kansas |
| Shirley Vian | March 17, 1977 | Wichita, Kansas |
| Nancy Fox | December 8, 1977 | Wichita, Kansas |
| Marine Hedge | April 1985 | Park City, Kansas |
| Vicki Wegerle | September 16, 1986 | Wichita, Kansas |
| Dolores Davis | January 19, 1991 | Near Park City, Kansas |
Rader was convicted only for these 10 murders. Claims that he killed additional people remain unproven unless supported by charges, forensic evidence or an official law-enforcement conclusion.

How Dennis Rader Communicated with Police and the Media
Rader repeatedly contacted law enforcement and media organizations. His communications included letters, poems and packages containing information connected to the crimes. He appeared frustrated when his actions did not receive the level of public attention he wanted.
These contacts helped connect several murders and showed his desire to control the investigation’s public narrative. After a long silence, he resumed communicating in 2004, creating the trail that eventually led investigators to him.
Why Did Dennis Rader Stop for Several Years?
Rader’s last confirmed murder occurred in 1991, but he was not arrested until 2005. He claimed that work, family responsibilities and reduced opportunity affected his behavior. Because those explanations came from Rader himself, the accurate conclusion is simply that no later murder has been confirmed.
How Was Dennis Rader Caught?
Rader was caught through a combination of digital evidence, surveillance, investigation and DNA analysis. The most famous clue came from a floppy disk he sent to a local television station in February 2005.
Before sending it, Rader had asked whether information on a disk could be traced. Police communicated that it would be safe, but investigators were able to recover metadata after receiving it.
The metadata connected the disk to Christ Lutheran Church and contained the name Dennis. Investigators searched the church’s public information, identified Dennis Rader as the council president and began examining his background.
They also reviewed surveillance recordings associated with package locations and investigated a vehicle resembling one Rader drove. Each clue helped narrow the inquiry until police had enough evidence to act.
The Floppy Disk Mistake That Revealed His Identity
The disk did not solve the case by itself, but it gave investigators a specific identity to examine. Its metadata connected a document to the church and a user named Dennis. By reappearing and sending digital material, Rader created investigative opportunities that had not existed during his silence.
How DNA Evidence Helped Confirm the Case
Once investigators focused on Rader, they needed stronger evidence connecting him to the murders. Authorities learned that his daughter, Kerri Rawson, had previously received medical care at Kansas State University.
With legal authorization, investigators obtained access to a stored medical sample and compared its genetic profile with DNA evidence from the Vicki Wegerle crime scene. The comparison indicated that the person who left the crime-scene evidence was closely related to Rawson.
This was familial DNA evidence rather than a direct sample initially taken from Rader. Investigators later obtained additional evidence after his arrest. Rawson did not know in advance that her old medical sample was being used in the investigation.
The use of Rawson’s sample later became part of wider discussions about medical privacy and police access to stored biological material.
Dennis Rader’s Arrest and Confession
Police arrested Rader near his home in Park City, Kansas, on February 25, 2005. The arrest shocked his family, church and community because his public life appeared far removed from the person police had pursued for decades.
Investigators questioned him, and he eventually admitted that he was BTK. Police searches recovered records, photographs and objects documenting his planning. Charged with 10 counts of first-degree murder, he initially pleaded not guilty but later admitted responsibility in court.
Trial, Guilty Plea and Sentencing
On June 27, 2005, Rader pleaded guilty to all 10 charges. On August 18, 2005, a judge sentenced him to 10 consecutive life terms, requiring at least 175 years before parole eligibility. Victims’ relatives also addressed the court and explained the continuing damage to their families.
Why Was Dennis Rader Not Sentenced to Death?
Rader did not receive the death penalty because his murders occurred before the applicable law allowed that punishment. Kansas reinstated capital punishment in 1994, three years after his final confirmed murder. The law could not be applied retroactively, so consecutive life sentences were the strongest available punishment.
Where Is Dennis Rader Now?
As of September 2026, Dennis Rader remains imprisoned at El Dorado Correctional Facility in Butler County, Kansas. He is serving 10 consecutive life sentences.
Public reporting says he is held under restricted conditions and separated from the general prison population. His housing and privileges can change, but his sentence makes release during his lifetime effectively impossible.
Is Dennis Rader Still Alive in 2026?
Yes, Dennis Rader is still alive as of September 2026. He is 81 years old and remains in Kansas state custody.
No authoritative announcement has reported his death. Online rumors should not be treated as confirmation, especially when they do not cite the Kansas Department of Corrections, a court, a family representative or a reliable news organization.
Because his age and health make this a recurring search question, any published article should include a visible “last verified” date. That makes it easier to update the page promptly if his status changes.
Dennis Rader’s Health and Life in Prison
Detailed official medical records are not public. In 2023, his daughter described him as frail, shorter than he had once appeared and using a wheelchair when she visited him.
Those observations suggest age-related physical decline but do not confirm a particular disease or terminal diagnosis. Reports say he remains separated from other prisoners and has received limited privileges, although prison rules can change.
Who Was Dennis Rader’s Wife, Paula Dietz?
Paula Dietz is Rader’s former wife. The two married on May 22, 1971, and had two children together. Dietz reportedly worked as a bookkeeper and participated in her family’s church life.
Their marriage lasted approximately 34 years, during which Rader committed all 10 confirmed murders. Investigators did not accuse Dietz of participating in or knowingly concealing them.
Did Paula Dietz Know About Her Husband’s Crimes?
There is no credible evidence that Paula Dietz knew Dennis Rader was the BTK Killer before his arrest. No criminal charge was filed against her, and authorities have not publicly identified her as an accomplice.
Hindsight can make confusing events seem like obvious warnings, but it does not prove Dietz understood them. She and her children experienced their own trauma when Rader’s identity became public.
Dennis Rader and Paula Dietz’s Divorce
Dietz filed for divorce after Rader’s arrest and guilty plea. In July 2005, a Kansas judge granted an emergency divorce and waived the standard waiting period because of the effect the situation was having on her health.
Rader did not contest the filing. Reports state that he signed over the family’s property and his retirement benefits to Dietz.
She later moved away and maintained a private life. Reliable information about her current home, health and relationships is limited.
Dennis Rader’s Children: Brian Rader and Kerri Rawson
Rader and Dietz had two children: Brian Rader, born in 1975, and Kerri Rawson, born in 1978.
| Child | Known information |
|---|---|
| Brian Rader | The older child; has largely remained outside public life. |
| Kerri Rawson | Author, speaker and advocate who has discussed the effect of discovering her father’s crimes. |
Brian has chosen privacy, while Kerri has spoken publicly about trauma, faith and families affected by violent offenders. Neither child knew about their father’s crimes before his arrest.
Who Is Dennis Rader’s Daughter, Kerri Rawson?
Kerri Rawson is an author and advocate who learned about her father’s arrest from an FBI agent in 2005. The news forced her to reconsider almost every childhood memory and caused significant emotional distress.
In 2019, she published A Serial Killer’s Daughter: My Story of Faith, Love, and Overcoming and later wrote Breaking Free. She has also helped investigators interpret her father’s writings. In 2023, she visited him in prison seeking information that might help families connected to unresolved cases. The 2025 Netflix documentary My Father, the BTK Killer presents the case largely through her experience.
Was Dennis Rader Connected to Other Unsolved Cases?
In August 2023, the Osage County Sheriff’s Office searched the site of Rader’s former home while reviewing the 1976 disappearance of Cynthia Dawn Kinney from Pawhuska, Oklahoma. Officials recovered items for examination and described him as a prime suspect. However, Rader has not been charged, and no court has found him responsible. An Oklahoma cold-case organization said in October 2025 that no verified evidence proved he committed a homicide in Oklahoma.
The correct wording is that he has been investigated as a possible suspect, not that he has been confirmed as Kinney’s killer.
Why Dennis Rader Was Ruled Out of the Shawna Beth Garber Case
Rader was publicly discussed in connection with Shawna Beth Garber, whose body was found in Missouri in 1990. Investigators later said witness information pointed to another man, Talfey Reeves, and considered the case resolved in 2024. This is why suspected connections must never be written as established facts.
Dennis Rader in Books, Documentaries and Television
Rader’s crimes have been covered in numerous books, documentaries, podcasts and fictional productions. Notable works include:
- Confession of a Serial Killer by Katherine Ramsland
- A Serial Killer’s Daughter by Kerri Rawson
- Breaking Free by Kerri Rawson
- BTK: Confession of a Serial Killer
- My Father, the BTK Killer
- The podcast series Monster: BTK
The Netflix drama Mindhunter includes a character inspired by Rader, often called the “ADT Serviceman.” It is a dramatized series, so its scenes should not be used as factual evidence.
My Father, the BTK Killer Netflix Documentary
Released in October 2025, My Father, the BTK Killer focuses on Kerri Rawson’s experience of discovering her father’s identity and living with the consequences.
The documentary uses interviews, family material and case history, with particular attention to the trauma carried by Rawson and others. Viewers should still distinguish documentary storytelling and personal memory from official court records.
Dennis Rader’s Net Worth
There is no trustworthy public estimate of Dennis Rader’s current net worth. Websites that attach a precise figure to his name generally do not provide tax records, court filings or other evidence supporting the number.
Before his arrest, Rader earned ordinary employment income and lived with his family in Park City. After his arrest, he reportedly transferred property and retirement benefits to Paula Dietz as part of their separation.
He has spent more than two decades in prison and is not known to maintain a conventional public career or business. It is more accurate to state that his finances are undocumented than to publish an invented net-worth estimate.

Conclusion
Dennis Rader maintained the appearance of an ordinary community member while secretly committing 10 murders in Kansas between 1974 and 1991. His decision to resume communicating with police and the media ultimately exposed him. A floppy disk pointed investigators toward his church, and familial DNA helped confirm that they had identified the right suspect.
He pleaded guilty in 2005 and received 10 consecutive life sentences. As of September 2026, he remains alive at El Dorado Correctional Facility with no realistic possibility of release.
The case continues to attract attention through documentaries, books and unresolved-case investigations. However, responsible coverage must distinguish Rader’s confirmed crimes from speculation, protect the privacy of uninvolved relatives and remember the 10 people whose lives were taken: Joseph Otero Sr., Julie Otero, Joseph Otero Jr., Josephine Otero, Kathryn Bright, Shirley Vian, Nancy Fox, Marine Hedge, Vicki Wegerle and Dolores Davis.
