Dennis Rader was most proud of the murder he dubbed "Project Fox Hunt."
Nancy Jo Fox, 25, was smart, hard working, and had a good sense of humor. She worked days full-time as a secretary for a construction business, and nights at a jewelry store.
When Rader noticed her going into her home he marked her as his next potential victim. He stalked her for a long period of time. He obtained her name from her mailbox, he found out where she worked, and showed up there.
As always once he knew enough about a person to feel comfortable, he would select a date and time to carry out his attack.
On December 8, 1977, he parked two or three blocks away from her home. He knocked at the door, when nobody answered he cut the phone lines before breaking in to wait for her in the kitchen.
" ... what I call a perfect -- a perfect hit. Although she gave me a lot of verbal static, she cooperated, she didn’t fight me."
"I had complete control of her, that’s why it was one of the more -- more enjoyable kills, as I call them."
Rader told her he had to tie her up for sex due to a sexual problem. She called his fantasies "ridiculous." She tried to hurt him by clawing at his testicles, but in his high it aroused him more.
They talked and smoked a cigarette as he searched her purse. She said she wanted to get it over and asked to use the bathroom. He told her to be undressed when she came out; when she did he slapped his handcuffs on her.
He laid her on the bed to tie up her feet. On top of her he used his belt to strangle her. When she was almost dead, he let up so she could gasp for another breath.
"I had her come back and I whispered in her ear a little bit. I told her I was BTK, I was a bad guy. And then she really squirmed and then -- I pulled -- put the pressure down on it."
He did not have sexual relations with her. As she died, he masturbated.
Rader took a few personal items and cleaned house.
When he called the Emergency Communications Department to take credit for the death of Nancy Jo, who he referred to as his "seventh victim," his voice was recorded on the automatic taping system. The call was tracked to a phone booth but the caller only spoke for seconds.
"Yes. You will find a homicide at 843 South Pershing. Nancy Fox."
Attempts to get him repeat his statement were interrupted by a telephone operator, still on the line, repeating the address.
The caller said, "That is correct," before disconnecting.
He spoke 15 words during a three-second span of a seven second recording. The audio quality of the call, taped at a slow speed, so was poor it was not released to the public until August 1979. The tape was sent to the Washington DC, FBI laboratory but it was too brief and distorted by background noise to make a comparison voiceprint.
Nancy Fox, was found dead on Dec. 9, 1977.
"Fox went the way I wanted it."
It was reported that Rader was "sexually charged" by the court testimony about the murder. Rader wrote two poems about Nancy.
One of the clues he sent out was a dark haired doll with makeup, its arms were bound behind by pantyhose and the head was covered with a plastic bag. Next to it was a copy of Nancy's driver’s license.
At the sentencing, Nancy's sister Beverly Plapp said, " ... On the day he dies, Nancy and all of his victims will be waiting with God and watching him as he burns in hell."
Rader believed Nancy would be his primary mistress in the afterlife.
