As it turns out, local law enforcement hadn't contacted him. That was today.
I replied to his Friday email saying they'd ship Friday or Saturday today to ask about tracking.
Edit to add:
He has at least two business' - the other one is Velocity Engineering. I don't think they make the parts, either. I think it's his design firm, where they may build a prototype or two. He lists himself as owner/lead designer there

Again, nice stuff.
