Possession of a property

[Steve A Spann]

I wondered what anyone thinks about possession of a property. I bought this house at a Pennsylvania upset tax sale and there was the prior owner living in the property. He wouldnt get out so I took to the magistrate and the case was delayed because he 302'd himself when he found out i was taking him to the magistrate. He was in the mental ward at the local hospital for 2 weeks and then returned but has since left the property and im not sure where he is now. If hes not currently living there do i still need to fight for possession?  thank you
