Reading the story of the Colt family, made me remember the story from Austria several years ago where the father had kidnapped his own daughter, I believe she was 16 at the time, he had kept her in the basement dungeon he built in the family home, he fathered several children with his daughter, then his wife raised the children. I don't believe the wife had any idea what her husband was doing, these children would show up on the doorstep with a note from the daughter saying she couldn't care for them.
When thinking that maybe they lived very remotely, the popular Dora items makes me discount this.
When thinking of the dumpsite, I think that the person wanted the remains found, they could have taken and scattered the bones all over the place, with the vastness they could have thrown a bone here and a bone there, yet they choose to leave them intact not far off the road.
The older gentleman, was he walking proudly with his head up, did he have his head down, was he walking with a hurried pace, was he casually strolling, did he appear to be nervous, did he have a normal gait, did he limp, did his clothes appear to be dated or were they more recent fashion. I have wondered if this older gentleman could also be a victim of abuse, if he has a mental handicap of some varying degree, he could be of a very compliant nature. I just can't see a rational older gentleman walking down the road carrying the remains of a child, like it's normal.
I wonder when they will get the DNA profile back of this little angel,
