"Devil Mom." Oh dear god, "Devil Mom." So much that even Steve ended up breaking down after giving the aforementioned "mother" the calling out she deserves.
Similarly, "Jailed for Life," about the mother, now in prison for life for her complete obliviousness as to what happened to her child, of a four year old boy who'd been burned, scalded, beaten, and killed, because his mother's boyfriend thought he was a homosexual. We repeat; he thought a four year old was gay, so he tortured and killed him.
