You are correct about Nevada law. See the detailed explanation regarding "relocation" cases here.
You can contact the police to ask, but they will probably tell you this is a "civil matter" if you do not believe the child is in imminent risk of harm, and in the company of his primary custodian, and refer you back to family court, where you should file a motion demanding the child's immediate return and, depending on the facts and history, consider requesting a change in primary physical custody based on the move (a recent amendment to the statutes makes such motions a bit easier to bring). If you are uncertain, you should consult with a family law specialist experienced in relocation and custody cases.
