Don’t think I witnessed your event, but I unfortunately viewed a similar event in a Southern California RV park a few years ago. Sadly it occurred in a RV pad just two spots over from mine. The oder permeated the park for several days. I departed earlier than planned due to the smell.Fortunately, he had a good sense of humor - but not so good that he didn't swear me to secrecy as a condition of getting me back home from the trip we were on together... LOL I'm sure he was kidding. Well, mostly sure. But I never did tell the story until after he passed!
No clue - never even heard of that happening...
