Skamania County, Washington passed a law regarding Bigfoot in 1969 declaring that "any willful, wanton slaying of such creatures shall be deemed a felony" subject to substantial fine and/or imprisonment. The fact that this legislation was passed on April 1 did not escape notice, but County Commissioner Conrad Lundy said that "this is not an April Fool's Day joke ... there is reason to believe such an animal exists." Hunter and Dahinden mention their own "speculation that Skamania County authorities had their ears tuned much more to the music of a publicity bandwagon than to any song of distress" for Bigfoot. Notwithstanding, the ordinance was amended in 1984 to preclude an insanity defense and to consider such a killing homicide if the creature was proven by the coroner to be humanoid.
