Criminal Minds Episode 8.05 The Good Earth

Finding a link between four men who went missing proves difficult for the BAU, who travel to rural Oregon in pursuit of their latest case. While all four of the men were health conscious, nothing else seems to connect them. When the latest victim's body turns up dead in the river and the other three men's cars are found, however, the pieces start to come together. We soon learn that the UnSub is a delusional woman who lives on an organic farm, and she's convinced that the only way she can save herself and her daughter is to use the bodies of her victims as human fertilizer.
