I will be the first to admit I am very surprised. Especially the father , during media interviews he always blurted out his answers in a straightforward manner , I did not sense deception or rehearsed answers.
Having said that , we should err on the side of caution in regards to inconsistent stories , inconsistent statements or deception by the parents , they could very well be trying to cover up other (inappropriate) things they may have been doing around that timeline (drugs) (not watching the child properly)
It would not be the first time that hiding what you were actually doing implicated you in something you were not doing. David Milgaard is a perfect example. A nurse had been murdered , he was in the vicinity , he was the only stranger in the peaceful little town , he had a record , he used drugs and alcohol , he was deceptive in all his police interviews, his story kept changing , he was found guilty and spent 23 years in jail.
He was innocent. DNA cleared him . Why were his statements deceptive ? Why did his timelines fail to reconcile ? Because he had been busy doing break-ins , and drugs , and drinking , and he lied left and right about his whereabouts .... he never took the nurse-murder questioning seriously because he knew he did not do it .... but by the time he told police the truth they had stopped believing anything he said . So did the jury.
Sorry for the ramble. Deception may be for other reasons , and we should keep that in mind. Thank you. If the parents did something to DeOrr , other than maybe accidental , I will eat my hat , and my shoes , and some humble pie.
