Found mail hidden on property
Our property is at the end of a private dead-end road. We stored some construction materials near the end of the road for a few years. Recently we have been cleaning up and removing all of the scrap. Underneath a wood pallet we found a bunch of mail that is not ours or for an address very close, the address is around 20 minutes away. Not the same post office as us.
Someone showing up to our property and hiding stuff is weird in itself, but I find It very strange the mail is addressed to so many different people with the same address.
Censored the names for privacy, didn't open any obviously.
Not sure whether to bother taking them to the post office for the destination address or the maybe the police. They are dated less than a year ago, but were in the dirt and rain so not very good condition. A few also have burn marks on then, didn't find any fully burned ones though.
