If my employer closes while I'm on leave, what are my rights?

Worked a county job for 24 years. 1 year away from retiring and collecting my pension when I went on leave because of a sexual harassment suit that I filed that was handled inappropriately by my HR department (which is another issue) In the meantime, my employer was sold to a private company. I have not heard anything from employer since I went on leave exactly a year ago today. My pension is frozen, I wasn't" labeled" as anything.....not out on worker's comp or disability or even fired. Unable to collect unemployment because of the worker's comp money I've been waiting on. No income coming in at all. Feel as if I'm getting the run around because of the harassment case. Can't get answers or even contact me old employer because it no longer exists. Thoughts??
