Book reveals Kansas serial killer's plans for 11th victim

A new book says the BTK serial killer planned to kill an 11th victim by hanging her upside down in her Wichita, Kansas, home. It's a story police heard from Dennis Rader himself in 2005, but decided at the time to suppress to protect the woman.

The story was made public in "Confessions of a Serial Killer: The Untold Story of Dennis Rader, the BTK Killer," which has a scheduled release date of Sept. 6. The book was written by professor of forensic psychology Katherine Ramsland.

The author says lust and a desire for fame and power drove Rader to kill 10 people in Wichita from 1974 to 1991.

Rader's daughter, Kerri Rawson, told the Wichita Eagle ( ) her father cooperated on the book because he's proud of his murders.
