Did Burke have special needs? (I'm totally new to posting about this case and do not know details enough to comment nor pretend to know most of any of the details more than what I learned back when it was fresh and on the news). I ask because I've worked closely with many many kids on the spectrum and "control of feces" e.g. smearing, holding, hiding it and keeping it, using it, etc. This is not necessarily always to do with "Serious stress" nor abuse. This is a fairly common issue, especially with those in that old group from the DSM called PDD (pervasive development disorder) If he did, this could account for many items in this case, though he was only 9 the social appropriateness, understanding and social capabilities could possibly account for a lot...especially since his younger sister often appeared much more mature than her actual years.
