Accessing Autopsy Report/Investigation Records?

My dad died a few months ago, and everything defaulted to his parents rather than to me.

I'm trying to access his autopsy report (if it's even available yet) and possible records the police may have from the night of his death. Any insight on how to access if I can? It happened in Georgia if that helps.

Additionally, and less importantly, what happens to the individual's personal items after an investigation?
