But why did the parents need to act in a way that it didn't give away to BR that something catastrophic happened? I also do not think at all that they acted that way. They must have been shocked and terrified of that situation and did not hide it. I also believe that Burke himself too was shocked and they all showed it, not hided it. I believe there was panic and terror in all of them. I never said that they tried to hide anything from Burke. They did not need to. And neither did Burke.
If it was an "accident" that happened - he just meant to hit her, not kill her. He saw her falling down to the ground after the blow and was scared that it happened. He must have been shocked and terrified himself too. Crying and panicking, trying to wake her up. He knew he hit her hard and told that to his parents after they came to the scene.
They never suppressed any of their emotions at that time. Why would they? It was an awful and unimaginable scene. Why would Patsy, John or any of them scream in this situation? It is possible.
I'm just saying that Burke, as a 9-year old, could have also thought differently - not immediately believing that yes now she must be dead, but thinking that maybe she is just unconscious at his parents will come and wake her up. I see that happening in a 9-year old's mind. Even I, as a parent, when I would come to a scene when my child has fallen down to the ground and my other child says that he hit her - I would not first assume the worst, that now she definitely is dead - I would also think that she is unconscious/ in a coma, or anything but dead. I do not think any parent who was not there when the blow to the head occurs, to see and witness the severity of the situation, would come to the scene and just assume that the child is dead. Not even if there was visible blood on the scene, witch there was not. There has to be something that makes you believe that your child is dead - you can not find her pulse , see a pool of blood or not feel her breathing.
I do not believe any mind games happened. Why should there have been? It was an scene of an accident. Parents did not witness the accident but heard from Burke what had happened and he explained it to them the way it did happened - he hit her hard on the head. They were all in shock - crying, screaming, yelling, saying sorry, asking questions, trying to wake her and etc - it is all possible. Burke told them that he hit her on the head and I see Patsy and/or John feeling her head with their fingers (as a parent would look for a bump) and by touching finding/feeling the fracture beneath her scull, understanding the severity of the situation for the first time - now they know that this is not just a hit on a head with an unconscious child, but rather a brain dead child who would never be herself again. The breathing must have been so shallow that they, in their panic, were not detecting it. The pulse must have been so weak that they could not feel it. Now they assume that their child is dead.
They send Burke away because he is panicking and crying, asking questions like "will she be ok?". They see that he needs to be consoled himself but as they are dealing with JB they are not able to deal with Burke, so they send him away and do not tell him that "you killed your sister" - why would they say that to their child? They loved JB and Burke. Burke went to bed without knowing if JB would wake up or not. And if his parents tell him that everything was fine and JB woke up later, a child believes his parents...
Anyway, I feel like my theory that I presented here is not seen as possible by many. I was hoping that by after all those years thinking about it writing it down here would help see things from another point of view, but I feel that maybe it does not serve this purpose. I'm not stating this all as the truth of what happened - it is just my theory and opinion that I see very possible. I do not want to defend it or explain why I think so over and over again...
