Personal Property After and Foreclosure Auction

[Andrew B.]

We purchased a foreclosure from the county auction 3 months ago and the person being foreclosed on left all his possesions in the property. We posted the door and tried to call him, with no response and now he has appeared out of nowhere wanting to know where his stuff is. He's claims to have been out the country for years! He stopped paying his mortgage and hoa dues 2 years ago ( with me having to pay the hoa fees of 14k) on top of the auction fee, which i had budgeted on doing anyway after we took title. 

We put his stuff in storage for the past 2 months which is more than most would do, but had to get rid of it in the end as its not my responsibly to keep it indefinitely. 

Does anyone have any advice on his rights after leaving it of more than 90 days and my rights to have got  rid of it? My attorney is away and was hoping someone on BP might be able to shed some light on the topic before i actually return their call.

TIA
