You would find all their stories on the internet. But the most well known case is Etan Patz and paulf's comment has the highlighted Etan in it. It is very well written and will give you all you need to know about the case. Although I am sure there are little bits and pieces on line that may add more to the story. No they were not in CPS. Etan was kidnapped on his way to school. Yes Jennifer is alive. Pedro Hernandez is sitting in jail and he has a mental condition. I would not be surprised if HIS family lied about him also. There is so much mystery to this whole story, you should really look into it.
