I am having a similar reaction with a different conclusion. I am uncomfortable with some of the insider gossip on this site. I wrote a post to that effect that was deleted, probably because it was directed at a specific poster. But I will say, in general, that the family has made it very clear that they want complete privacy. We should respect that and not post about the surviving family members.
I can agree about posting stuff about the family but on this site I haven't seen anything to that effect, it's mostly been sleuthing about the suspect or suspect(s). Sleuth is defined as to carry out a search or investigation in the manner of a detective & I thought that's what this site was about. I've seen some disturbing stuff from an individual about the family on another social media platform, but I think the MODS have done a good job making sure we are respectful of the family.
