I've thought off and on many times.. maybe it's my imagination, because I haven't studied other cases to see for sure.. but it seems to me that in missing child cases, there seems to pretty much always be someone who saw SOMETHING, even if it may have seemed insignificant at the time. There is a case here that is terrible.. a girl disappeared after school about 50-some years ago, never to be seen again. ... and that case is still mostly unsolved (police seem to believe they know who took her and killed her, and he is dead, and was never charged).. I so hope that this case is not 20 years or 50 years. In the case above, police discovered one of the girl's shoes on a roadway, and someone saw her talking after school to a man in a car, and the car was described. Even in that highly unusual C case recently, didn't someone see something, a vehicle I think? Just in my head, I feel like there's always something (or the child ends up being found quicker than not, alive or dead).. but in this case there is absolutely nothing. imo.
