Post California Tax Deed Auction Question

[Raymond C.]

Hi,

I recently won a property/land in a county in California with a mobile home on it.

I live about 3 hours away and when I went last Friday to visit the property, the PG&E (electricity meter) was still on and I heard a phone ring inside the house. The window blinds were all closed. I couldn't confirm if it's occupied, but I talked to two neighbors and they said the elderly owner died in 2015, but the sister visited the property a few times after, but not recently. Before I left, I put a note on the door indicating there's a new owner and left my number. By the looks of the outside landscaping and minor defects of the house, it does seem like it has been unoccupied... I'm just waiting until the county records my name on the deed and I will go and visit the property again to secure it. 

But my question is, IF someone is actually occupying the mobile home, can I change the locks and the electricity over to my name, essentially locking out that person who will be technically "squatting" since the actual owner died awhile ago and I as the new owner don't have any contract/ lease/ rental agreement arrangements with? Will I be violating the law in terms of wrongfully evicting if that's the case? 

Conversely, if no one is occupying the mobile home, but the previous deceased owner's stuff is there, and her sister just locked the doors and visits once in awhile, can I just toss the deceased owner's things away? How would one go about securing the property legally? Thank you in advance for any insights.
