I wonder if the firearms were delivered to him using his mother's UPS rented mailbox, or if he had rented his own UPS mailbox there so that the firearms could be delivered to him there.
Unless he had an FFl, he would not be able to receive the weapons at home ( a few exceptions may apply for very antique weapons / collectibles).
Rather, the transfer process would have apparently been:
- Crimo purchased at least one weapon from an out of state vendor.
- In purchasing the weapon, Crimo gives the vendor a local FLL holder's address (in this case, a local gun store- apparently a large one). The vendor then ships the weapon there.
- Crimo goes into pick it up and pays the FFL holder's transfer fee. This transfer fee covers the mandatory background check. The fee can range from pretty nominal to relatively high depending on the individual gun shop etc. Some seem to seek out large numbers of transfers. Others are the exact opposite and don't encourage it price wise.
The paperwork regarding the background check and weapon are then stored by the receiving FFL holder. Being responsible for the background check and associated paperwork might make the receiving FFL holder the technical seller, but he is really a broker.
- If the purchaser passes the background check, they can leave with the weapon. If they do not, they cannot take possession of the weapon. Instead, it is probably returned to the vendor who takes any return postage and re-stocking fees (probably hefty) out of the refund.
