So I recently saw The Buzzard’s Roost Cave Accident video on YT....

I go on a binge for these cave diving tragedies and this particular one, on multiple youtube channels, the narrator ominously states "the methods to remove Bill's body could not have been used on a living person." There are obvious implications to this, but I wanted to know exactly what happened? It's unlikely Reddit would allow explicit detail to be posted on a forum, so if anyone knows, DM me. If I get a DM with an explanation, you can message here and I'll respond under with a message letting anyone know what I learned.

Also if anyone has a PG-13 explanation, that's welcome here as well, in the comments.
