The cop showed up at their door step on 3 occasions during the week with the warning that the dog would be destroyed if it continued to attack the mentally handicapped woman in the neighborhood. After 3 attacks and no effort to keep the dog under control, the deputy was dispatched to kill the dog. It wasn't an "out of the blue" surprise. The action took place after multiple warnings and pursuant to Idaho law for dealing with vicious dogs.
Sorry, but I made my statement as to what the article stated. Nothing in the article about showing up 3 times and such.
