No sooner did I record an episode about the unsolved quadruple homicide at the University of Idaho, than I returned to my old home on the Palouse. I talk about what folks there told me about the murders, the national media and the investigation into the killings. It seems like everyone knows a little something about the case, but what no one can quite grasp is why they happened. And, as someone who grew up on the Palouse, it made me wonder -- are we culturally blind to evil? Is the idea that someone could kill just because they wanted to kill so foreign to us, that we can't see it or accept it?
