I saw this on the news today.
While the guy was in his late 80s and had known health problems, there's still some fishy stuff. Like how he died several hours after being transferred to a new location. Why is some sickly prisoner in his late 80s even being moved?
The whole thing seems suspicious. Not that I'm complaining; the guy allegedly murdered at least a dozen people.
