Robert Beattie, a Wichita lawyer, is the author of the nonfiction book Nightmare in Wichita. It is about BTK, a serial killer in Wichita, Kansas who created the name BTK after his modus operandi, "Bind Them, Torture Them, Kill Them". Dennis Rader started sending out letters to media again after hearing about the book. Right before he was going to publish it, Dennis Rader was arrested then convicted as the BTK Killer, a.k.a. the BTK strangler, and Beattie quickly wrote an epilogue. Rader murdered 10 people in the Wichita area between 1974 and 1991 but evaded law enforcement until 2005. Beattie is also known for interviewing serial killer Charles Manson for a class project as a professor at Newman University in Wichita, which stirred controversy and brought media attention to him. Language of Evil is about a murder in Douglas County, Kansas. Beattie ran unsuccessfully for the office of Kansas Secretary of State in 2006. He testified against the use of polygraph.
