Lost/Stolen Airpods but I know the location!

The story is complicated, and i'm not really sure what to do or how I can get them back but here is the breakdown:

The day before reading week I had an exam in STC at 8:30 PM that finished at 10:00 PM, stupidly I left my airpods on a seat before exiting the exam hall but I quickly realized right after the exam. I checked everywhere I was but could not find them. Throughout reading week, the airpods have been at someones house in Kitchner. I have their exact address but since its so far, my plan was to snipe them when they came back to campus. Yesterday, they came to the STC around 10:00 PM. I went around the entire building asking literally everyone and telling people I knew the address of the person who found them. I think I encountered someone who actually had them because the airpods have been in the STC since but are nowhere to be found. They probably got spooked when I told them I was tracking it and ditched it in the STC. I feel as if i've looked everywhere, and the sound/precise location is not working. I still have their address so hypothetically i could go to their house and ask them where they are in the STC but it would be an annoying 1 hour bus ride to their house. I have a Theory that it's one of the janitors that took it because timewise it would allign with their shifts. And also which student is driving to the STC at 10:00 P.M, TWICE!!! I talked to all of the janitors and they all seemed very nice and concerned. This is why i'm not 100% convinced its one of them.

Guys I genuinely don't know what to do. Its pissing me off that I know my pods are somewhere in the STC but still missing

If anyone lives near Franklin street in kitchner and is bored, let me know and I can provide you with an exact address.

Ive done almost everything I could've done besides going to their house, lmk if yall have any ideas though.

Thanks
