Watched it on Netflix months ago as well as watching additional social media footage on youtube and further reading about the case.
The social media stuff was absolutely cringe and the MLM stuff was even worse, and from what I saw, I personally think Shanann was a self centered narcassist and a pretty neglectful parent who looked at her children as pawns. Of couse we don't have enough information to tell, but I wouldn't be surprised if she had Munchausen syndrome by proxy, some of her interactions with her daughters that she posted on social media were truly bizarre.
I don't understand why people are so confused as to why Chris killed her, they were up shit creek financially and she seemed insufferable to be around, especially with the camera constantly being out, and it was clear the reason he killed his daughters was because he didnt want to be paying child support payments. Obviously, it's not the answer and he simply should have just left and not looked back if he wanted nothing to do with them. The thing that I can't get my head around is how in the hell he thought he would ever get away with this... I suppose he wasnt thinking, the majority of murders/disappearances are committed by someone(s) who knew the victim in some way, the fact that he thought he wouldn't be the main suspect and somehow thought that he would get away with it is truly disturbing, I would dare say he was a massive narcassist himself and a psychopath to some degree.
I resonate more with the daughters than I do Shanann. People romanticize murder victims, not all of them were great people just because they were killed, I remember there was a woman murdered on Norfolk Island a few years back and by all accounts she was an absolutely horrible person, doesn't excuse her being murdered obviously, but it might explain why she was murdered.
I think the most important thing to take from this is that some people just shouldnt have had kids, these two shouldnt have had kids, plain and simple.
