Using google I usually end with results in cell death. I found some layman articles, but that does not help. My main interest is the brain part.
I believe William Bass has written on this, probably in the Journal of Forensic Sciences, but no specific articles come to mind. I'd start by looking for his articles, then probably with a variety of search terms using a filter for that journal. It's not open access, so you'll need to use a library or institution that has a subscription.
