Owner dead, how to get in touch ?

[Malcolm Darensbourg]

I've been looking for a lot of ways to search for houses outside of the MLS. I came across a house on the sheriff sale that they'll be auctioning off soon. I got the homeowners name from the assessor's office, but there's one problem. He commuted suicide a year ago after he tried to kill his wife. What would be the best way to get in touch with the wife and how would you go about getting this deal closed ? Any advice will be helpful.
