Anyone know how old all three kids were? The parents didn't make a "mistake," they made an "on purpose." (They intentionally left her alone, right?) Of course they didn't INTEND for her to be kidnapped, but a lot of other bad stuff could've happened too. I wouldn't leave my kids alone even if the location was safe from intruders, simply because youngsters can HAVE ACCIDENTS and need immediate parental attention.

Basicially, if the girl is found she ought to be taken away from these silly parents and given to parents who care!
