Can't find owner of abandoned property

[Account Closed]

I was driving for dollars in Indianapolis, Indiana and found an abandoned property I searched the address on my local assessor site ( http://maps.indy.gov/AssessorPropertyCards/  )

only to find out the website hasn't been updated. 

The website says the owner still lives in the property I searched which is incorrect.

My question is how do I find and contact the owner if the address is the same as the abandoned property? 

Any local investors know what I could do in this situation?

Any help would be much appreciated thanks!
