On August 21, 1971, Pinell, George Jackson, and several other inmates attempted to escape from San Quentin. Three inmates and three guards were killed in the attempt.
Pinell was killed by another prisoner during a riot.
Noted: Warren G. Harding apparently did father a child with his mistress, Nan Britton.
Also noted: VonTrey Clark was allegedly offering $5,000 for the murder of Samantha Dean. (Previously.)
My great and good friend Joe D. and I have had past discussions about death at the Grand Canyon and at Yosemite (although I can’t find them now). In that light, this is interesting: “Forget bears: Here’s what really kills people at national parks”.
Short version: if you do die at a national park, it will probably be a drowning or a car crash. But statistically, the odds are low that you will die at a national park.
