In 1978, KAKE-TV obtained special permission from the police to place a subliminal message in a report on the BTK Killer in an effort to get the killer to turn himself in.

The subliminal message said “Now call the chief”, as well as picturing a pair of glasses lying upside down, as seen at the murder scene of Nancy Fox. Police hoped that seeing the glasses might stir up the remorse¬†of the BTK.

The attempt was unsuccessful.
