It will be an interesting investigation around this case. The bodies were found about 20 miles from the lake where they were abducted, so it seems to be a local crime. I still have a feeling that the parents' criminal/drug pasts may come into play in regard to motive for this awful event. I hope what they did as adults didn't cause this to happen to the girls.
In my opinion it's just WRONG for a parent to outlive a child regardless if the reason for the premature death. Both our kids are alive and well so I can only imagine how hard it would be to lose a child.
Its so sad and makes me more angry if the investigation shows that it was because of the parents' drug histories. What a load of guilt on their consciences, and hopefully there would be some legal recourse.
