buying probate - no heirs, owned by public administrator - IL

[Kevin Danikowski]

In cook county illinois I found a property in foreclosure which has no heirs, and thus was given to the public administrator. Further, this property is in pre-foreclosure (~12 months) but has a decent amount of equity. I would like to know how to purchase the property. 

I have contacted the probate office but it's been a week and they haven't gotten back. Should I go out of my way to try to find the public administrators direct contact? Is it even possible to purchase this before it goes to auction in some future date? thanks!
