Abandoned Property

Can you take an item from a abandoned house?

We purchased a home last October. When we moved in, we noticed the previous owners had left some property (sports memorabelia) in the home. The sellers left no forwarding address with us, so we mailed a letter to them at our address thinking maybe they forwarded their mail; they hadn't. We notified our realtor the week we moved in. We have searched the white pages online, but have not been able to find a telephone number or address for the sellers. It has been nearly ten months and we have not heard from anyone about the property. What do we need to do to legally claim the property as ours so we can give it away or sell it? I don't want to get rid of it and then have them show up and want it back, potentially putting us in a position where we would have to pay them for property they left behind nearly a year ago. The abandoned property laws I found in Oregon don't seem to cover this situation. Please let me know what the legal remedy would be to claim this property as ours.

I bought some acreage in the county a year ago. The deed is free and clear. There are no leases or other liens on the property. The property had some unlocked sheds with junk items in them and some other pipes, batteries, tires, etc., lying about the yard. I removed some of this stuff I considered trash and now an individual is threatening to file theft charges for my disposing of these items. This individual is not the person I purchased the property from and has nothing to do with the property to my knowledge. I never heard of him until a few weeks ago. Are the items left on the property by someone else, having no lease or rental agreement, and not on the deed as a lien holder, unmentioned at all until his phone call last week, considered my property or someone else?

A friend recently moved all of her belongings to my residence and then suddenly decided to move to Tennessee. She has been gone for 3 weeks and I have not heard from her. How do I go about getting her things out of here ASAP?

If an auto has been stored on private property for a number of years, is it possible to sell the auto without a title? The owner of the auto has not interest in it.
