I've thought of that angle also. Who would know that information? Could it be someone no one would suspect, but living in or working at that complex who often observed and listened to what was going on with the family and "friends?"
If it is, who? A neighbor, a maintenance person, friend of a friend?
I've thought about what kind of sicko this pedophile is and ruling out mafiosa type activity and a horrendous act that says...I'll show you...here are a few of the things I've come up with. All conjecture - I'm sure everyone can see traits in this animal that are worth investigating. If Nevaeh was sexually assaulted, I'm going with the idea there was one pedophile. Pedophiles, as far as I know, do not ever work in pairs. Sharing the prey that has brought them so many pleasurable fantasies isn't what they do.
Conjectures:
1. What does encasing your victim in cement mean? This is highly unusual for a pedophile who usually throws his prey (object) aside as garbage to be eaten by parasites and bugs and lost forever. Could this be his intense need for control over his victim. Put the little thing in cement and she'll stay there forever - no more chasing and fighting for control of her. Can you imagine how cowardly he must be to go to such extremes to control a 5yo? (this is conjecture)
2. He encased Nevaeh in cement for ultimate, endless control, so why was he so sloppy with the cement work? My guess - This slug is not attentive to detail and probably has not been his entire life. He screws up over and over - just can't seem to get it right. Tough place to be for a control freak isn't it? (conjecture)
3. Nevaeh was placed in a beautiful spot - tranquil, near the river's edge, and underneath trees. Hardly did this low-life place her there so she would be in lovely resting place. NO, he did it for him, it's all about him. Perhaps, HE enjoys the tranquility and beauty of it all. Maybe this low-life doesn't have the chance to be outdoors much, or if he does, it's not in a peaceful, quiet environment. So that's where he places his catch of the day..just to remind him of his wonderful work and what a peaceful world it is out there.
4. Even though he placed her in a spot HE thought was tranquil and beautiful, he also placed her in an area that attracts other people with an affinity for the outdoors. A place that was sure to have traffic - a place where she was sure to be found. This may tell us he likes to pat himself on the back for a 'job well done'. He likes all the attention he's receiving from newspapers, having the town on edge, and being hunted by all. He seems to enjoy the deception and fame of it all.
Whoever and whatever this freak is - he is twisted and dangerous. Maybe he works in Nevaeh's school, or is a person doing ground work in an apartment complex, or a maintenance man who loves the outdoors. Or maybe he none of those things...One things for sure - he's twisted.
