2Hope ~ See Bessie's excellent posting of the law regarding kidnapping, specifically I-a - if a person knowingly takes, entices, detains or conceals a child or causes the child to be taken, enticed, detained or concealed, "with the intent to detain or conceal such child from a parent, guardian, or other person having lawful physical custody "
That person is guilty of kidnapping. That person's guilt has nothing to do with what the minor child wanted. So for a person to feed her, house her, clothe her and conceal her from Law enforcement it's a crime. This is why it is so important to get the word out - there can be no question, in this case that Abby is internationally known and there is no reasonable excuse to conceal her from Law Enforcement Especially if they believed she was in danger and thought they were protecting her.
By the way you did not have the intent to take, detain, or conceal since no one was looking for them. But yes, always let LE and CPS professionals intervene. If the child is in danger, they are the people charged with that child's best interest, IMO
