None of this may be true, but if any of these points are true, this is significant.
She says that a "source says investigators believe this was a burglary gone bad". Perhaps things were taken from the house that LE hasn't revealed? Money or jewelry missing? Wonder what is different now that makes LE say this? If, indeed, they really are thinking that this was a burglary gone bad.
And then she said that a source says that there's "widespread belief by investigators that NG could be alive". Doesn't give any reasons that they believe that NG could be alive but they may have compelling evidence that points to this. If this is true, I imagine we might hear more about this from LE.
If this source is accurate, these points are a very big deal and LE is possibly much further along in this investigation than would appear to the public.
I don't understand how "a burglary gone bad" could quickly pivot to the perpetrators taking NG from the house and without any planning, take her somewhere safe and keep her alive without NG seeing who they are.
