WICHITA, Kan. —  Excerpts from BTK communications sent to Wichita media outlets in the 1970s. All spelling and grammatical errors are as written:

"I'm sorry this happen to society. They are the ones who suffer the most. It hard to control myself, You probably call me 'psychotic with sexual perversion hang-up'. Where this monster enter my brain I will never know. But, it here to stay. How does one cure himself? If you ask for help, that you have killed four people, they will laugh or hit the panic button and call the cops."

"How many do I have to kill before I get my name in the paper or some national attention?"

— Excerpt of letter sent to KAKE-TV in 1978.

"What is this taht I can see,

Cold icy hands taking hold of me,

For Death has come, you all can see.

Hell has open it,s gate to trick me.

Oh! Death, Oh! Death, can't you spare

me, over for another year!

I'll stuff your jaws till you can't talk

I'll blind your leg's till you can't walk

I'll tie your hands till you can't make a

stand.

And finally I'll close your eyes so you

can't see

I'll bring sexual death unto you for me.

B.T.K."
