After watching show about it , i see a key element in the case where there wasn't much talk about the mother and the baby being found . I suspect that the killer has ties with the mother and knew her well. Think all the other killings were random at most but to kill a mother and then kill the baby and dump it so far away seems that it was a personal matter. I say it how could he get a baby like that unless he knew her. No prostitute would take there baby with them . And not many have there kids anymore for what they do for a living. So they should look into her and the child there is something about it that stands out from the others and may help solve a lot.... Let's hope they are caught soon....
