Hi I am another newbie from SA. Firstly, croup would have made it near impossible for CR to scream out. My son used to suffer from it, and I have also had it in the past. The poor darling never had a hope of screaming for help
That makes the alleged killer even more cruel; he would have known that. Such an opportunist!
Much like it was always apparent to me that it was someone close to the family as they knew exactly when the brother of the family was returning home. This crime IMHO was completely planned, if not days before, then at least in the hours before. It was not a spur of the moment thing, and I think he took a weapon with him.
