Pittsburggirl while I agree with your statement about Jacyee Dugard and her stepfather not being responsible is correct however I do not recall him ever being accused as a matter of fact I beleive he gave chase on a bicycle but was unable to catch up with the car as well the abduction was witnessed by fellow classmates and he was quickly cleared as a suspect, the actions of Ron Cummings and Misty Cummings Croslin and Casey Anthony are completely diffrent from those of Dugards step father, as far as I know Duggard's step father cooperated with LE, while none of these players have. Duggard's stepfather gave useful information such as a discription of the car and those responsible, while these players have continiously tried to foil the efferts of LE as well as volunteers to the point of making threats...... My point is that it is unfair to compare these two cases to Jaycees case.
As far as the statement of pure speculation, you are also correct, because at this point we have nothing else. There are not any hard facts in Haleighs case, and honestly there aren't many hard core facts in Caylees case, and that alone is a comparison. The facts as known in Caylees case are... Caylee was last in the care of CA. CA did not report her missing for 31 days, for 31 days CA partied and acted as though nothing was wrong, once the fact of Caylee being missing was known CA lied and those around her lied....... In Haleigh's case she was last known in the care of Misty, Misty did not report her missing until Ron came home, Since her disappearance Misty and Ron have partied and acted as if nothing is wrong, and when ever confronted with the facts they lie and those around them lie, SO take it as you will... The comparison's are obvious to me. Just sayin
