Property Owner Deceased for 4 years, Still owner of record

[Graham McBain]

There is a property in my area where the owner passed away 4+ years ago but her name is still on the assessors website. The family still lives on the property but according to the assessor none of them are on the title.

How do I find out the story on this place, specifically if it's in probate &OR where I should send me offer/marketing.
