How to track down somebody's heir

[Tyler McGill]

BP community,

I have a house in my neighborhood that has been condemned for months now and is starting to have some significant problems. I am also interested in possibly buying it as a BRRRR. I don't think I've ever seen anyone actually living there, and my neighbors tell me the original owner passed away and his son-in-law inherited it.

Bottom line is that the HOA and the city have "fined" the owner multiple times, and apparently sent multiple letters to the property listed as the owners. However, after all of that correspondence, they have never heard anything back.

Is there some part of the legal system that can help me track down who might have inherited this property?  If not, how would you proceed with tracking down the title holder?

Thanks!
