BTK Killer = Bind Torture Kill:
"Police in Wichita say they're now certain that a poem sent to a TV station in 1979 was written by the serial killer known only as BTK. Now, they're appealing for help from anyone who might have more information.
The initials BTK were used on letters claiming responsibility for eight Wichita deaths between 1974 and 1986. The killer went silent before sending more letters this year.
Police called a news conference today to discuss a poem sent to TV station KAKE in June 1979. Investigators believe the poem is tied to a burglary at a home where BTK's intended victim failed to show up at the expected hour.
The TV station received a photocopy of the poem, which is called ?Oh Anna, Why Didn't You Appear?? Police now hope to hear from someone who might have seen the original writing."
