When it came to Beth though, her RAD was quite severe. In fact, the doctors felt the need to document her condition and her adoptive parents agreed. The interviews, which were later on published, show a 6-year old Beth talking about her plans to kill her family with the knives she took from the kitchen. And considering the fact that she was speaking in a completely apathetic manner, the interview footage was both shocking and incredibly disturbing. Beth bared her every thought, and most of them were as distressing as the next.
