To clarify my post a few pages back:
I realize it is illegal in most places to communicate sexually with a minor. I just feel that if Nicole didn't have proof they met in person (telling her young friends they did is not proof), her age is set at 18 on Social Media, and David is 18, it could look like he was looking for a girl around his age. I just honestly don't believe that law enforcement would have taken it that serious if Nicole was not harmed, especially if they looked at her social media accounts where David met her and saw the age lie and all the older guys. LE would have told her parents to keep an eye on her like they did in another case I followed. LE had to track this guy down online. I don't think they'd have gotten warrants or used those resources if she was alive and well. Look at how serious everyone took it when her friend at school tried to tell and get her help?
Like I said, David could clearly see these men and how they talk to Nicole, and yet she never retaliated against them. She was caught talking to older men and judging from the timing, most likely David, on her phone saying lord knows what (her Dad said it was bad) and what happened? She lost her phone privileges for a short period of time. No one went after David or any of the other guys. If he was so worried he could have cut contact right then and if the parents still somehow confronted him later he could have said he didn't know her age but when he found out she got in trouble and why, he cut things off. This wasn't all that complicated to get out of at all.
And honestly, David knew what he was doing. Nicole didn't have a real name for him, he met her near her home the time they met according to her, so she didn't know where he lived either.
She was smitten with him. I don't believe that he couldn't have come up with some story about why he wouldn't be able to see her for a while, it would have only taken a few sweet words. Then he could have drifted off until she found a new "boyfriend".
Then there is the BIGGEST reason I have for not believing he only killed her because she was going to tell. If this guy thought he covered his tracks well enough to get away with murder, he must have felt he covered his tracks well enough for the relationship with Nicole. He used the same methods and mode of communication to set up both the relationship and the murder. Well, all that plus the 3 extra weeks he gave her to possibly tell.
I firmly believe that if this was about fear of getting caught and being humiliated publicly and having his life ruined, he'd have done this deed all by himself. There was no need for a second person.
This is all just my opinion and I respect and enjoy reading others, I am no expert on law or psychology so my view could be completely wrong in the end. Lord knows, that has happened often enough!
My opinion would definitely change if Nicole turned out to be pregnant as some have speculated, but for some reason I really don't think she was chosen for sex. I feel she was chosen because they thought it would be easy to lure her out and to kill her.
