To be fair, Melanie believed this was an inevitable death (as we all have), but they just happened to know the timeframe ahead of time through revelation. She did not think (one could argue naively) they were plotting and orchestrating these deaths. So, they weren't "discussing murder", they were talking about the future where "calamities" would occur.
I recently listened to a class given by one of these speakers. It was held in an LDS Church building classroom. I presume by the acoustics and other things, probably the RS room or something of similar (Medium) size. At least 5-10 different voices were heard asking questions, gathering up their things, etc. and I assume others who did not speak. One woman asked when she could arrange for the speaker to be in St George, UT. She said she had "at least 30 people" who would like to hear him speak and several others chimed in with assent.
They openly spoke about portals, becoming translated beings, and FEMA setting up essentially Satan's deceptive version of white tent cities, which meant they were essentially concentration camps.
I was appalled. This is apparently much more prevalent than many members of the LDS community realize, and I do think it's possibly entirely in the ID/UT/AZ corridor (which i don't live in, which is why I think this shocked me so much? I've had zero exposure to this before this case). Disturbing enough that I am reaching out to my UT family members to sound the alarm--make sure they and their children are aware and prepared to think critically about these things and proactively quash.

ETA: this was not on par with the conferences we've heard about. This was a (I think Sunday) evening meeting of hyper-local folks.
