We don't know that this is a kidnapping yet. Not at all. (most LE analysts have recently chimed in with this).I wouldn't say there isn't anything to suggest family. It has been said, even on this forum, that random kidnappings are extremely rare. They often involve people close - and since NG wouldnt have business associates, a scorned lover, and any other non-familial person that makes sense - to look at family or in-laws is reasonable.
It is just as likely that this was a murder and the body was disposed. It right now is technically a missing persons. And the ransom can be an opportunistic scam not related to the initial event that made NG disappear.
We as the public actually have very little information on all these aspects thus far (and I keep seeing people repeating conflicting reports or misinformation). edit- but yes, to look at the family is very reasonable.
