Apple Watch around 211st 83 Ave?

I had a lady come to my door today morning saying she lost her Apple Watch yesterday and the app is pinging at my house. I told her I don’t have her watch, feel free to look in the area outside my house. Says she has already done that and she hasn’t even walked in this area so obviously someone found the watch and has it in this house. That she should probably call the cops. I also checked with my tenant, they didn’t have it either. She was on call with someone who kept saying they are obviously lying. Also insisted if the Apple app is showing this place, it has to be here. I could not even reason with her that this might be an approximate location and you could ask the houses nearby. So anyway did anyone in this area find a watch? Also did you come across something like this? Scam or not, if she comes again I will call the cops to sort this out.
