EDIT: I did also
I'm not too certain about that. I think as the outbreak started, Clem's dad probably got attacked by some "crazy" guy outside of the hotel. In this case, crazy = zombie (at least in the beginning) So, Clem's dad is almost assuredly a zombie or dead by now. The old man on the radio could be anybody, really. Maybe he was staying in the hotel - or working there.
On a side note, The Marshall House in Savannah is supposedly haunted, along with everything else in that town. Cool place!
