My thoughts exactly. The whole story just doesn't make sense.
These are people whose whole LIVES don't make sense to "normal" people, I'd say. It's a chaotic situation, possibly with certain elements which I am sure you can intuit (let's say closeness) . . . and not one in which a child would flourish. Distanced, distancing language . . poor little Shaylyn and what happened to her, and what she might be experiencing and feeling IF she was abducted . . . seems to mean nothing to them.
