That's the alias of Dennis Rader, who gave himself the name BTK (it stood for "bind, torture, kill"). He was a serial killer who was active from 1974 to 1991, murdering 10 people (he wasn't caught until 2005). This was 1979, right in the heart of his rampage, and Rader stalked Anna Williams for months. Finally, while she was out, he broke in, cut the phone lines, picked out a few souvenirs to take home for his collection and waited.
And waited. And waited.
When Williams got home, she found that her house had been broken into, and that her phones were dead. She looked through the house to find ... there was no one there.
Rader had gotten tired of waiting and just left.
