The most logical suspect is someone that knew the boys. A stranger, IMO, could not subdue them. A stranger attack usually requires compliance, and, based on the information given, I don't think these boys would have just sat there. These boys were not that weak. Stevie Branch was frequently beaten by his father and he usually carried a knife; in other words, he wasn't a wimp. The person that murdered them knew that they could be a handful. I think that if anyone other than an authority figure or someone who they previously feared tried to attack them they WOULD have stood up for themselves. They would have screamed, would have tried to run away or make a scene. The person(s) that killed them knew their weaknesses, IMO. Also, the theory that someone that knew them murdered them is supported by the fact that ALL THREE of them were murdered. If it was a stranger and he had just murdered one of the boys, he probably wouldn't go through the trouble of killing ALL THREE unless they KNEW HIM. The suspect already knew that if he killed one he would have to kill all three because they must have known him already. Even if they had seen a strangers face, they are only 8 years old. Any logical person would just let them go once reaching the intended target. It just doesn't make sense that all three would be murdered unless they knew the actual killer. This was a personal crime, IMO. I also believe that this was not premeditated and I say this because the killer happened to use objects at his disposal...the boys' shoelaces were used to tie them up, most likely the weapon of choice was a blunt object on the ground...he used things that were just lying around. IF it were premeditated, I think we would have seen duct tape, rope...more evidence that this was an organized criminal, more evidence that this was planned. The killer was smart and resourceful but I don't think he was very organized. I think he just used what he had and he happened to be incredibly lucky in that regard. All of this is my opinion of course...
