So this is their last thread. About ~20 days after "might CTB tonight", looks like they had made an attempt at partial hanging, which failed.
After that, they were considering N.
There was talk of compromise with parents with thumbsup.
1-2 examples and their own example would remove their current desire for CTB.
Which was screenwriting.
After that, there's nothing more.
So there are many possibilities, I'll list, might be upsetting to read.
1. Repeat hanging was success, self-ban by investigators/family, reasonable
2. Family discovered evidence of attempts/interrupted attempt, self-ban by family, reasonable
3. Compromise success, self-ban, without non-lethal goodbye post, reasonable
4. Obtained N or another method, any kind of self-ban, maybe went through it or not, without goodbye post, reasonable I guess. They sound young, they mention school and no money, so it depends a little on whether they can even afford N.
etc, and I cannot say with certainty which is the most likely outcome from last thread, it leaned towards recovery, kinda, but effective attempt/s in recent past means high risk of ctb too.
We'll probably never know for sure, unless he reappears.
