Tax delinquent property, but owner is deceased

[Niqque Waters]

Hello! I’m currently interested in a property that is delinquent on taxes $722. I believe that’s a year or two behind. Tax collector office confirmed its delinquent, but not in the tax sale yet and that I should contact owner for outright sale ( not knowing they’re deceased). Should I contact next of kin? Children? Probate? Quit claim deed?What would be the best way (investors perspective) to go about in attempt to redeem?/gain ownership? 

Thanks
