For 31 years, the BTK serial killer toyed with Wichita, Kan., sending macabre clues and puzzles to police and media about the 10 people he murdered to fulfill his sexual fantasies.
Yet it was the murderer's surprising naivete that ultimately led to his capture, said Sedgwick County, Kan., District Attorney Nola Foulston, the lead prosecutor of BTK killer Dennis Rader.
"We then got a piece of information that will go down in history as one of the Darwin Awards," Foulston told the crowd yesterday, referring to an award for people who do stupid things.
Inside one cereal box, Rader left a note asking police whether he could send them a diskette without its being traced to his computer. He asked police to place a classified ad in the local newspaper that said, "It'll be OK, Rex" and left a P.O. Box number and code number.
(Undercover police had a tough time convincing the newspaper to run the ad, Foulston said. Sales representatives thought it was advertising prostitution, and refused to accept it from an undercover female police officer. It was published only after an undercover male officer submitted it.)
In all, Rader talked to police for more than 32 hours, describing in disturbing and photographic detail all 10 slayings, Foulston said. He enjoyed the slayings so much that he got aroused just describing them to investigators, she said.
When he learned police would obtain a search warrant for his house, he drew a map of it and told where he kept mementos from each victim, including jewelry and underwear.
Investigators asked Rader whether anything happened in his childhood that could explain his behavior, Foulston said.
Rader said that as a boy, he watched his grandparents strangle chickens at their farm. He soon began killing animals.
By age 29, he started killing people. Rader never raped or sodomized any of his victims; his deviant pleasures came from watching them die, Foulston said.
