Hello, everyone. I'm new to the forums, so I hope you don't mind my butting in with a few comments and questions.
Firstly, I just wanted to make an observation about people wondering how one person managed to keep the three girls quiet and under control. I just wanted to point out that Hart did manage to kidnap two young women. If two adults can be controlled, isn't it likely that three young girls could be even more easily controlled? The fact that one scream was heard suggests to me the scenario that the killer surprised the children, someone screamed, but he quickly got them quiet. At night, with a weapon, I don't think it would be difficult to scare children into doing what you wanted. I don't think this is proof that there must have been more than one person.
Secondly, I have a question about the footprints. One was a boot and one was a tennis shoe, correct? Which was inside and which was outside? Another question, do we know if they were bound before or after they were killed? My understanding is that there was tape over the mouths of at least two? Wouldn't it be likely that they were bound before being killed? That could account for no one hearing them screaming during the attack. Also, if Milner was treated differently than the other girls, do we know who was killed first? That could give us some clues.
I'm undecided about what I think right now, regarding the number of killers and whether Hart was involved or not. I'm still reading up on everything, but I have a theory.
