The student is signing for the package, I bet the dealers reuse fake ID or reuse the same airbnb places. Now do controlled delivery next time those addresses with patterns have packages and merely threaten the student into cooperation or follow them for second controlled delivery and bust entire crew for conspiracy to traffic which is a decade in jail at least, especially interstate trafficking. This is a weak criminal scheme made weaker by taunting the police by telling a journalist about your scheme, now they have to bust you to save face.

If your threat model is "DEA busts darknet seller" they'd get a big stack of delivery addresses where drugs have been sent.

If a bunch of those addresses turned out to be AirBnB they could subpoena the details of who paid for the leases. Especially if their orders were large enough to indicate they were selling the stuff on.
