"Dialogue between the parents and the infant" does sound like he expects at least some people to have seen DeOrr alive, though.
Alive when though? Obviously throughout his life. I wish this had been clarified by SB- in the last month? Week? Year? I wonder if there was a stressful event that occurred at some point during Deorrs little life that could have triggered treatment of him that would have been observed as unusual by bystanders or family?
