That effing SUCKS !
Sorry to hear it-

I would contact the Packers and report it, it would double suck if somebody else got ripped off tomorrow.

There's also a 0.1 % chance somebody turned em in to Lost & Found because they thought your family accidentally left em behind. ???

Aren't there are cameras and security everywhere at TC, maybe they picked up something on film ?
Especially since you have photos of the units and know where you were sitting.

Good luck, I'm cheering for a Happy Ending 🙏
