Passenger's side rear tire found nailed by screw!

Just found the passenger's side rear tire had a screw nailed on it around 6PM after work.

The screw look familiar. It is same type of screw that made flat tire on my wife's Honda CRV.

I recall that I went to 18780 Tilson Ave. Cupertino, CA to pick up mail from mail box around noon. So, the nailed issue maybe happened from there. Just can't think of any where that may have such screw. I should ask tire repair technician to keep the screw as evidence tomorrow.
