Here's a summary I posted in /r/TrueCrimeDiscussion about the case. He has since deleted his account, which I completely understand.

Basically, this guy was seeking help for his crumbling marriage on reddit, people were encouraging him to file for divorce, he finally did...and the worst possible thing happened. She murdered their kids.

Well, I found out about the reddit connection later on, but it happened in my area, so I heard about it on facebook first. I don't know them personally, but I live close enough that I was seeing the "go fund me's" on my wall. I thought it was odd that there was more than one. I think one was set up by his employer, and that makes sense. Then one was set up by the husband's family to pay for funeral expenses. But then another one was popping up that was set up by her family also claiming to pay for funeral expenses. I thought it was weird that both sides of the family were both setting up go fund me's to pay for the funeral--why didn't they go in on one together? I didn't say anything because it's obviously a sensitive subject.

Anyway, the husband/redditor later posted in legal advice that his in-laws set up a go-fund-me were claiming they were paying for the funeral, but it was really going to her legal bills. It got shut down not long after. Such a heartbreaking situation. :-(
