Double-posting to say, I wonder whether this caving accident could have been a trigger in terms of giving an idea to someone who wanted to get rid of Susan.
It was all over the news, as was the idea of "sealing" the cave with the body inside. Only a hermit in Utah could have missed this story.
This particular cave was sealed on Dec. 3. However, it is in the west desert, west of Utah Lake, according to what I can find online. And according to other websites, there are a lot of other caves in the area.
I wonder whether a perp:
- saw the news and got an idea about how to "seal up" a body
- went out to the area on the news to investigate and find perhaps another cave, including finding that metal grates cover some caves and would need to be opened
- or might even have tried to put a body in this cave to be sealed. When the news announced it would be done within 2 weeks, they had to act fast. But the cave was sealed in just a few days, so an alternate cave with a metal grate had to be found
