The BTK killer was Dennis Rader, a Kansas man who used “BTK” to describe his crimes. He pleaded guilty to ten murders committed between 1974 and 1991 and received ten consecutive life terms. His case returned to public view when he resumed communicating with police and media in 2004; a diskette he sent eventually helped investigators identify him.
What does “BTK” mean?
Rader chose the name BTK, an acronym the FBI expands as “Bind them, Torture them, and Kill them.” The FBI’s 2008 case summary identifies ten victims. The name was Rader’s own label, not a clinical description of him or an explanation of the crimes.
What crimes did Dennis Rader plead guilty to?
The Kansas murders established in court took place from 1974 through 1991. Rader pleaded guilty to ten murders in Sedgwick County District Court in Wichita. His June 27, 2005 plea hearing included accounts of the crimes before Judge Greg Waller; the transcript was reproduced by The Smoking Gun.
In that testimony, Rader used the term “trolling stage” for what he said was a period of seeking potential victims before focusing on and stalking a person. That was his description of his own actions, not a general or independently validated framework.

How was the BTK killer caught?
Rader communicated with police and media during the years after the crimes began, then stopped. He re-emerged in 2004, prompting a task force led by Wichita police with the Kansas Bureau of Investigation, the FBI and other agencies. The FBI also describes support from its Behavioral Analysis Unit, including a proactive media strategy.
The FBI’s 2008 account says investigators received eleven communications during the eleven-month 2004–2005 investigation. The final communication included a computer diskette containing information that eventually identified Rader. The eleven-communication figure applies to that investigation, not to all of Rader’s communications over the years.

Authorities have considered whether Rader might be connected to cases beyond the ten Kansas murders, but suspicion is not proof or a conviction. In a 2023 Associated Press report, sheriff’s officials described Rader as a “prime suspect” in the 1976 disappearance of Cynthia Kinney, last seen in Pawhuska, Oklahoma. Oklahoma District Attorney Mike Fisher said there was insufficient evidence to charge Rader and requested a formal investigation by the Oklahoma State Bureau of Investigation. That report does not establish what happened to Kinney or whether Rader was involved; it records the prosecutor’s position at that time, not a current status update.
